Unit design features

The tiller’s device is a self-propelled car on two wheels, equipped with an engine removed from a VP-150M scooter. The reason for choosing this particular engine was that it has such a constructive solution, thanks to which forced cooling of the cylinder head with air is carried out.

Such a motor from a scooter is capable of operating at the lowest speeds at fairly high loads.

For the construction of the tiller, the master used control cables, engine mounts, and also a double arc of the frame, handle and chain taken from the scooter. The rest of the construction details were manufactured

Separately, the designer made a U-shaped frame welded from pipes and a wheel axle turned on a lathe. He also made 3 homemade hinges for the main and control rods. They will be used as connecting elements between the tiller itself, its rudder and the plow.

A steel pipe is attached to the frame of the unit by welding, ending with an axle, which is necessary to tension the cables going to the engine gearbox. The tension itself is carried out by means of an oscillating rocker arm, the gear lever of which is a welded piece of steel pipe.

The pitch of the chains used to create the device is 12.7 mm and 15.9 mm. The number of teeth in the sprockets: output shaft. 11, output shaft. 20 and 60, travel axle. 40.

We build a tiller according to the instructions from Arkhipov

What can you generally build on your own?

The factory-made tiller market offers customers a fairly wide range of products for every taste. However, the for such agricultural machinery are far from being able to be mastered by many. Therefore, in the gardens in rural areas, you can often find a homemade tiller, which, in terms of operational parameters, is not nearly inferior to the factory analogue.

Craftsmen most often use parts of old motorcycles and scrap metal when creating universal designs.

Outdated motorcycle models often serve as the basis for the manufacture of various homemade products and small-scale mechanization tools useful in the household.

Since homemade tillers are often created from improvised old materials, the Druzhba saw motor, which is well-known to many, is often used as the engine of the unit.

On the basis of homemade tillers, craftsmen create tools no less important in agriculture, for example: plows, as well as hillers for hilling corn or potatoes

One of these masters is the inventor Valentin Arkhipov, who is the author of the manufacture of a number of useful devices and the construction of all kinds of household equipment.

A talented designer has created a multifunctional device with which you can not only plow and harrow the land, but also plant, huddle tuberous crops, as well as harvest and rake the tops

Therefore, when thinking over how to make a tiller with your own hands, it is better to opt for this proven and successfully applied option. Any person can handle a simple and easy-to-use agricultural unit.

What is this design good for??

There are more than a dozen analogs of such a model, but in comparison with them, the original Tiller model of the Kaluga master has a number of indisputable advantages.

  • Swivel connection. Most of these models have a rigid connection, which makes it difficult to maneuver the machine and thus makes it difficult to work with it. The details of this agricultural unit are connected by means of hinges. This makes it possible to change the direction of movement during work, if necessary, without removing the plow from the furrow.
  • Offset of the axis to the direction of travel. Many owners, when cultivating the soil using a tiller, faced such a difficulty that in the process of moving forward under the influence of soil resistance, the unit is pulled to the side. A lot of effort should be made to align the furrow. To compensate for such a skid, the foreman positioned the plow axis at a slight angle towards the direction of travel. When plowing, the structure is slightly turned to the left. The desired position can always be adjusted with the three link pivots.
  • The level of the set plowing depth. If in other models the plowing depth is maintained by lowering or raising the plow, then when working with this tiller it is done automatically. Regulation is carried out by changing the angle of the plow in relation to the furrow. The structure is equipped with a field board, which acts as a lifting force when burying the plow. If, on the contrary, a ploughshare appears above the surface of the earth, then its angle of attack instantly increases, under the action of which it again plunges into the ground to a given depth.

We make a tiller with our own hands using the example of a design from Valentin Arkhipov

It is not an easy task to process a plot with a large area, where a significant part of the territory is set aside for a vegetable garden, using only improvised tools. Loosening, digging, and weeding the garden by hand take a lot of time and effort. It’s good when there is an opportunity to purchase a tiller, which will become an indispensable assistant on the site. But to facilitate the work on the ground, you can also make a tiller with your own hands.

Step-by-step device assembly technology

The assembly of the structure begins with the arrangement of the running shaft. To do this, a housing with bearings is attached to it, an asterisk is welded on and overrunning clutches are mounted, which will perform the function of a differential during operation. After that, the structure is equipped with wheels and a frame. A telescopic rod, plow and steering wheel are installed on the fixed frame.

The main elements of the travel shaft: 1. shaft, 2. sprocket, 3. cover, 4. bearing housing, 5. support platform, 6. bearing No. 308, 7. overrunning clutch housing, 8. dog axle, 9. dog, 10. ratchet, 11. bearing No. 307, 12. washers, 13. wheel, 14. pawl spring

The agricultural tiller is equipped with special wheels, which, unlike rubber analogs, are able to provide better grip.

These metal wheels are not clogged with earth. When in contact with the ground, they do not compact it, but rather loosen it

To connect the frame of the unit with the engine mount and the frame of the scooter itself, two arcuate pipes are used. Between them there is a place for placing a fuel tank.

To equip the engine, a bracket is used, ending with a steel axle with a length of 150 mm. The bracket is welded cantilever to the U-shaped frame of the structure. A motor with a suspension is suspended on the axle itself. The assembled structure is connected to the arched arches of the frame. Only after that the secondary shaft is mounted, the control cables are pulled and the chains are tensioned.

The main elements of the control unit: 1. connecting axle, 2. strip, 3. pipe, 4. handles

Connecting elements of the structure: 1. main rod, 2. control rod

How can you upgrade a homemade tiller?

Arkhipov’s tiller is multifunctional. It can be used as a plow, or as a cultivator. To do this, it is sufficient to replace the detachable parts for the plow with parts with the cultivator blades removed. the tiller will deepen the furrows into the ground as it advances and place potato tubers in them. To plow the tubers, you just need to install the dumps in place and walk the unit between the planted rows.

Sprouted plants can be huddled according to the same principle. You can learn more about how to independently design a hiller for a tiller from the material: https://diz-cafe.com/tech/okuchnik-svoimi-rukami.html

The agricultural unit is also convenient for harvesting. Using different plows, you can change the working width. The unit is also good in that it is able to collect missed potatoes and the tops of plants left after harvesting. For these purposes, it is equipped with a rake or harrow.

The universal design can be used not only for agricultural work. In winter, it is successfully used to remove snow. A faithful assistant is also useful for cleaning the paths of the local area. By installing a roller with a round brush and an additional sprocket on the tiller, the owner will make it easier for himself to work on clearing sidewalks.

Dependence of the minitractor on the gearbox

the tiller is designed to facilitate the labor of landowners. In order for it to work properly and reliably, plowing the ground, removing leaves and dry grass, planting, it is necessary to have a sufficient supply of power and speeds. To learn how to reverse on a tiller, you need to familiarize yourself with its structure and tasks assigned to it.

The reduction reversing unit is called a creeper. They are equipped with all modern gasoline or diesel-powered air-cooled units. This addition allows the agricultural machine to work safely under increased loads, such as digging potatoes, cultivating heavy soil, plowing. With this creeper unit, it becomes possible to increase power and eliminate wheelset slip.

You need to choose the power depending on the size of the area of ​​the site:

  • 5 h.p. from 6 to 10 acres;
  • 6 h.p. no more than 30 acres;
  • 7 h.p. up to 50 acres;

For larger plots, a power exceeding 7 hp is chosen. The installation diagram includes a gearbox for a minitractor, it is fixed on the drive shaft, where there is a gearbox next to one side, and a clutch assembly on the other. It is represented by gears that are meshed with a gear train. The reversible gearbox provides a set of required speeds. If you decide to make it yourself, then it must be reliable and withstand the load in difficult areas.

You can simply borrow this unit from another device. a motorcycle or mini tractor. It is important to take into account the gear ratios. The reverse gear on the tiller has a ratio of 1: 4.62. Compliance with these values ​​guarantees the normal operation of the unit: improved driving and traction performance and relieving the drive gearbox.

Reversible gearbox manufacturing

If you want to build a node at your own discretion, then you cannot do without a borrowed case. Outside the factory conditions, it is impossible to make it yourself. Cast iron or aluminum alloy is used as a material. The body is produced on special equipment. To make a reversible gearbox at home, you need to start with the case. If it was not possible to pick it up from other mechanisms, then it can be built from a gas pipe with thick walls with an outer diameter of 2.73 cm. Internal components: axles, gears. They must withstand the loads that a homemade reverse gearbox will be subjected to. Regarding oil seals, bearings, fuses, it is recommended to choose them based on the design.

A homemade reverse unit can actually be assembled from the elements that make up the main gear on a used GAZ-69 car. Hubs, bushings for reverse, sprockets, stem, fork are machined from metal. Steel 45 is suitable for this. Finished parts must be hardened. You should be very careful with the manufacture of cams on the hubs, as well as reversing bushings, since they will be subjected to increased dynamic loads. The drive and driven gears must be isolated from each other by a gasket, the thickness of which can be adjusted to the degree of their pressing.

How to make a reverse gearbox with your own hands

The reverse gear is included in the main part of the tiller. the drive. The durability of the tiller depends on its reliability. The task of such a gearbox is to preserve and maintain the performance of the machine in difficult conditions.

How to properly assemble a gearbox

Diagrams for switching the direction of movement of an agricultural machine are as follows:

  • The drive sprocket located on the main shaft transmits the torque to the bevel gear, which is the leading.
  • 2 driven bevel gears are mounted on a splined shank. One of them, which is meshed with a reversing bushing with a slot on the main shaft, starts to rotate. In this way, the transmission goes either to the differential or to the wheels of the machine.
  • The reversing device stem is equipped with a fork. It throws the direction change bushing to the right in one direction, or to the left in the other direction, or to neutral. This is how commands that change the direction of movement are carried out.
  • Homemade reversible gearbox controlled by a stem lever.

A self-made step-down unit will be considered of high quality if the following factors were taken into account in its manufacture:

  • rated power;
  • permissible boundary temperature under extreme conditions;
  • rotational speed;
  • permissible loads on axles and parts;
  • the value of the angle of the gearbox;
  • torque value;
  • type of lubricant for rubbing parts;
  • frequency of work.

If you improperly operate the gearbox for a mini tractor, then it may fail. This may be due to the following reasons:

  • excessive load causes a large release of heat, this leads to overheating of the shaft and transmitting parts, teeth breakage is possible, shocks will be heard in the chassis, uncontrollability will appear in reducing the speed;
  • wrong choice of gear ratio;
  • neglect of current repairs, which includes a preliminary inspection of the engine and major components.

Thus, since the tiller has a certain range of speeds, it is therefore important that when switching them, all nodes remain operational.

A self-made gearbox provides an increase in power with a sharp drop in speed to a minimum value.

The lowering unit must necessarily complement the design of the machine, since it is used to cultivate the land, remove snow, leaves, grass, various materials.

The main elements of the bevel gear

The components of the bevel gear are: generator housing, flanged bearing, rotor shaft, steel washer, steel flange, bevel drive gear, bevel gear housing, steel key, pinion shaft bearings (2 pcs), driven pinion shaft, bearing steel housing pinion shaft, pulley mount, V-belt pulley, flange mount.

Homemade bevel gear for tiller

The tiller gearbox can be made by yourself. To do this, you will need to calculate the rated power (Pn); Pn = Pe (hp) xFS, as a result of which the correct type of angle is determined for the bevel gear. Torque and RPM are also calculated.

You also need to determine the operating conditions of a home-made gearbox for a tiller, which includes: radial and axial loads on the shaft ends, minimum and maximum temperatures, determination of environmental conditions, intermittent or non-intermittent operating cycle, type of lubricant.

After determining the technical parameters, you can start assembling the bevel gear.
To do this, select the bevel gearbox housing.

For example, you can use a factory one, from a Ural or Dnepr motorcycle. Then, based on the diameter of the gearbox housing, we make the gear shaft bearing housing from steel. Here we use an appropriately sized drill and a vernier caliper. Then, in accordance with the intended dimensions, we select the gear shaft bearings (2 pcs).

Install a steel flange on the back of the gearbox. It will have a steel washer and a flange bearing inside. Using a few screws, attach the steel flange to the generator body. Before that, we select the driven pinion shaft, steel key and pinion gear. All units are connected to the transmission mechanism and the shaft of the rotary generator. The V-belt drive pulley is located on the transmission mechanism and is attached to the driven gear shaft with a nut and a spring washer.
To assemble a homemade bevel gear, you will need the following tools: a caliper and a ruler, a straight and Phillips screwdriver, metal drills, metal files and files, wire cutters and pliers, rubber gaskets, a vice and a hammer.

tiller with gear reducer

To understand what a gear reducer is, consider the structure of the transmission. It transfers torque from the engine to the wheels, and changes the speed and direction of the tiller. The transmission consists of a gearbox, differential, gearbox and clutch. Transmission units are gear, chain, belt or combine one or the other.
The gear transmission consists of bevel and spur gears (gear reducer). It is used on some models of cars and heavy tillers. The figure shows the gear transmission of the Tiller “Ugra” NMB-1, where a gear reducer is used.

tiller with gear reducer and reduction gear for tiller

A reduction gear for a tiller, a creeper in the common people, is installed on modern diesel and gasoline air-cooled tillers. Thanks to this, the user can use the tiller on especially heavy soils for plowing and digging out potatoes. Reduction gear helps with wheel slip when its own power is not enough.

Do-it-yourself reduction gear for the tiller

One of the most important elements of a tiller is the drive. If you need to purchase a gearbox for a tiller, then you should know that the service life of the entire unit will depend on its reliability. A gearbox for a tiller, (made by hand), is designed to convert and transmit the torque that it receives from mechanical transmissions and makes agricultural machinery work.

How to make a gearbox for a tiller with your own hands

There are several important differences between worm and chain gearboxes for a tiller: gear ratio, efficiency, number of shafts and gears, angular speeds and power.

Tiller angle gearbox

The angular gearbox is widely used in motorcycle technology: in the automotive industry, modified cultivators, industry. When installing an angular reduction gear on tillers, at high loads, more efficient work is achieved.

This type of gearbox is typically used to mate the motor to a chain-sized transmission. The angular gearbox for the tiller is made from available samples, similar to those installed on Dnepr or Ural motorcycles. Then you will need to modify the gearbox.

What are the gearboxes for tiller

Non-collapsible gearboxes are usually installed on cheap tillers. The design of such a unit is not particularly reliable. It also has a short service life. In addition, it is impossible to carry out repairs or disassembly-assembly. In the manufacture of such units, low-quality metal and non-cased parts are used. In order to understand why it is impossible to use the gearbox for a long time, you need to familiarize yourself with its diagram.

It is customary to install collapsible gearboxes on expensive tillers. Thanks to this, you can disassemble the tiller gearbox and carry out maintenance. Repairs the tiller gearbox to increase service life, if high-quality spare parts are used when replacing defective elements.

It is imperative that you regularly diagnose the gearbox in order to repair the required unit in time. Regular lubrication of the gearbox must also be carried out, which will allow the unit to be used for much longer.
Most often, a tiller gearbox is used to convert a high angular velocity to a low one. The input shaft shows a high speed and the output shaft shows a low speed.

In order to avoid unexpected breakdowns, it is necessary to carry out regular maintenance in order to successfully operate the agricultural machine. If the change in angular speed occurs in steps, the gearbox is called a gearbox, if the change occurs continuously, it is called a variator.

How to make a gearbox for a tiller with your own hands

There are several important differences between worm and chain gearboxes for a tiller: gear ratio, efficiency, number of shafts and gears, angular speeds and power.

What it is?

First you need to figure out what a gearbox is. It is a mechanism that ensures the movement of the cultivator. The tiller gearbox converts torque into driving force. The device is sometimes called a transducer. The service life of the tillers depends on it, therefore it is very important to pay attention to the quality of the parts when choosing.

The dimensions of the gearbox depend on the dimensions of the mechanized motor vehicles.

Angular

One of the most efficient and reliable gearboxes. Therefore, it is used to equip production machines and equipment operating under heavy loads. This type of converter is also actively used in the automotive industry.

The angular gearbox provides the connection between the engine and the transmission, which is designed for chain transmission. Please note that the magnitude of the load will depend on the quality of lubricants and temperature conditions.

Chain

The name is due to the design of the gearbox, which is based on a chain as a transmission element. In one device, it can be more than one. The movement is provided by asterisks, small. leading, large. driven. The principle is similar to that of a system on a bicycle. Performance and reliability are highly dependent on the quality of the materials used to manufacture the main driving parts.

Among the negative points, the need for regular maintenance should be highlighted: chain tightening, lubrication. Unlike a belt drive, the chain drive prevents slipping and lasts longer.

Equipment

The converter can be collapsible and non-collapsible. As a rule, budget modifications of tillers are equipped with the last option. Their difference is in less expensive parts that cannot be replaced. In the event of a breakdown, you will have to change the entire gearbox. Manufacturers determine the service life of such models from one to two seasons, no more, provided that the device is used correctly.

expensive equipment is equipped with a collapsible gearbox, which can be repaired by replacing failed components. Therefore, the service life increases significantly.

The following items are included in the package of the converter.

  • Housing. Depending on the type of gearbox, it can be collapsible or not.
  • Rotor shaft that provides torque.
  • Gears of different sizes.
  • Chain or belt depending on the type of gearbox.
  • With a chain drive, movement is carried out using sprockets. toothed discs.
  • With a belt drive, the mechanism is equipped with pulleys on which the belt is put on.
  • Bearings. Since all parts rotate, it is necessary to reduce friction and allow the elements to rotate freely. The bearing is designed to cope with this task.

All parts are inside the case. In addition to the standard set of accessories, elements for lubricating bearings can be added inside the device, for example, an oil pump or a cooling device.

Depending on the type of transmission used in the gearbox, converters are divided into several types. Different devices are used in mechanisms of different fields of activity.

One of the main parts of the tiller engine is the gearbox. If you understand its structure and own the elementary skills of a locksmith, then this block can be built independently.

Gear

Gear reducers are most often used in heavy equipment engines. The transmission consists of a gearbox, differentials and governor, gears and belts. The design of the device is simple.

The gear transmission contains bevel or spur gears. Due to the fact that several of them can be placed on one shaft at once, the dimensions of the converter are reduced.

Inside the gearbox, the gears work in pairs, so the ratio of the number of teeth on the driving and driven parts should be observed. Since freedom of rotating elements is required, the gear reducer requires regular lubrication and oil.

Among the advantages, one can also highlight the noiselessness of the engine on the specified type of gearbox.

Downward

The task of the reduction gear is to reduce the number of revolutions, while increasing the power. This is achieved by using a gear system. As a rule, modern converters of this type are equipped with an air cooling system.

Motors based on them are reliable, multifunctional and can withstand significant loads. Therefore, they are installed on tillers used for work on heavy soils.

tiller with gear reducer and reduction gear for tiller

Tillers with modern characteristics are quite acceptable for installing a reduction gearbox. After all, they are equipped with special air cooling.

Even heavy soil when plowing potatoes is not terrible for a machine with such a unit. You can provide fast wheel slip, and other additional features.

Do-it-yourself reduction gear for the tiller

The most important part of the tiller is the drive. He is the main of all the elements presented in the tiller. Therefore, when it becomes necessary to buy a gearbox, all its further work, and even the functionality of the tiller depends on the quality.

A gearbox for a tiller is a certain type of device capable of transmitting, appropriately converting torque, for which mechanical transmissions are conductors. Accordingly, agricultural machinery will work more productively.

Angle reducer for tiller

In the automotive industry, bevel gears are often used. Effective work is achieved by installing such a unit.

This type of gearbox is needed to ensure the docking of the transmission with the engine itself. You can take a ready-made gearbox by simply modifying it.

tiller with gear reducer

The gear reducer is easy enough to understand if you look at its transmission. It is the transmitter between the wheels and the engine. The direction in the tiller is changing.

The gearbox, together with the clutch, is called the transmission. In heavy tillers it is often used.

Homemade bevel gear for tiller

In principle, the gearbox does not have a very intricate structure; it is quite possible to assemble it yourself. First, do the correct calculation in nominal power (Pn); Pn = Pe (hp) xFS. This will allow you to make a choice in favor of the correct angle to be determined for the bevel gear. According to this principle, not only the number of possible revolutions per minute will be calculated, but also the calculation of the torque.

A self-made gearbox needs to determine the conditions for its operation. Among them there are radial loads, or axial ones, which are present at the shafts, at their ends. Its operation will be optimal if the temperature, type of lubricant is correctly selected.

After completing all the above steps, you can proceed to the assembly. The case can be selected from the factory. The diameter of the housing will tell you what the bearing housing will be for the shaft. To help a caliper and a good quality drill. Next, we take two bearings under the shaft itself.

It is important to install the steel flange on the front of the gearbox. Accordingly, inside: bearing, necessarily flanged and washer. The flange is attached to the generator itself using screws. The steel key, together with the drive pinion and the driven pinion shaft, must be selected in advance. All units are connected to the rotary generator, which are connected to the transmission mechanism. It has a pulley that provides V-belt transmission. It should be secured to the driven shaft using a nut with a lock washer.

Tiller gearboxes what they are

When you have tillers available that are relatively cheap, they often have simplified gearboxes that are not collapsible.

In this case, the service life is significantly reduced. Any additional possibilities are excluded, including: repair, and, accordingly, assembly, replacement of parts, or disassembly, to check the condition of the unit.

This means that the material from which the gearbox itself is made is of very poor quality. Most of the parts presented in the assembly will not be cased. The gearbox diagram will allow you to present not only the principle of its operation, but also to determine the service life.

Expensive Tillers have gearboxes with a more complex structure, the possibility of further assembly and disassembly. Maintenance can be carried out by correcting any malfunctions in the gearbox. Repairs must be carried out in order to extend the service life of the operation. It is important to replace faults in parts with other, more expensive items. Gearbox lubrication also extends its useful life.

In most cases, the gearbox serves as a speed converter. That is, the angular velocity quickly and efficiently goes to low. The input shaft will show a high angular velocity, the output shaft will already be low.

Unforeseen breakdowns are prevented by constant and quality maintenance. With stepwise variation in speed, the reducer is called a conventional gearbox. In the case when it does not work in a stepwise system, it is called a variator.

How to make a gearbox for a tiller with your own hands

Reducers of two types, which are called: worm gear, as well as chain, have several small, but rather important differences. They are contained in characteristics that are inherent in two types, but gearboxes operate with different: efficiency, angular speed, number of gears, as well as shafts, ratio between gears.

The main structural elements of the bevel gear

The gearbox has several main elements, including: a flange, a housing from the generator itself, a pulley with a V-belt type of transmission, a steel washer, a pulley mount, a steel key, a rotor shaft, a flange mount, a flange bearing and others.

How to make a gearbox for a tiller with your own hands

There are several important differences between worm and chain gearboxes for a tiller: gear ratio, efficiency, number of shafts and gears, angular speeds and power.

What are the gearboxes for tiller

Non-collapsible gearboxes are usually installed on cheap tillers. The design of such a unit is not particularly reliable. It also has a short service life. In addition, it is impossible to carry out repairs or disassembly-assembly. In the manufacture of such units, low-quality metal and non-cased parts are used. In order to understand why it is impossible to use the gearbox for a long time, you need to familiarize yourself with its diagram.

It is customary to install collapsible gearboxes on expensive tillers. Thanks to this, you can disassemble the tiller gearbox and carry out maintenance. Repairs the tiller gearbox to increase service life, if high-quality spare parts are used when replacing defective elements.

It is imperative that you regularly diagnose the gearbox in order to repair the required unit in time. Regular lubrication of the gearbox must also be carried out, which will allow the unit to be used for much longer.
Most often, a tiller gearbox is used to convert a high angular velocity to a low one. The input shaft shows a high speed and the output shaft shows a low speed.

In order to avoid unexpected breakdowns, it is necessary to carry out regular maintenance in order to successfully operate the agricultural machine. If the change in angular speed occurs in steps, the gearbox is called a gearbox, if the change occurs continuously, it is called a variator.

Homemade bevel gear for tiller

The tiller gearbox can be made by yourself. To do this, you will need to calculate the rated power (Pn); Pn = Pe (hp) xFS, as a result of which the correct type of angle is determined for the bevel gear. Torque and RPM are also calculated.

You also need to determine the operating conditions of a home-made gearbox for a tiller, which includes: radial and axial loads on the shaft ends, minimum and maximum temperatures, determination of environmental conditions, intermittent or non-intermittent operating cycle, type of lubricant.

After determining the technical parameters, you can start assembling the bevel gear.
To do this, select the bevel gearbox housing.

For example, you can use a factory one, from a Ural or Dnepr motorcycle. Then, based on the diameter of the gearbox housing, we make the gear shaft bearing housing from steel. Here we use an appropriately sized drill and a vernier caliper. Then, in accordance with the intended dimensions, we select the gear shaft bearings (2 pcs).

Install a steel flange on the back of the gearbox. It will have a steel washer and a flange bearing inside. Using a few screws, attach the steel flange to the generator body. Before that, we select the driven pinion shaft, steel key and pinion gear. All units are connected to the transmission mechanism and the shaft of the rotary generator. The V-belt drive pulley is located on the transmission mechanism and is attached to the driven gear shaft with a nut and a spring washer.
To assemble a homemade bevel gear, you will need the following tools: a caliper and a ruler, a straight and Phillips screwdriver, metal drills, metal files and files, wire cutters and pliers, rubber gaskets, a vice and a hammer.

tiller with gear reducer and reduction gear for tiller

A reduction gear for a tiller, in common people a creeper, is installed on modern diesel and gasoline air-cooled tillers. Thanks to this, the user can use the tiller on especially heavy soils for plowing and digging out potatoes. Reduction gear helps with wheel slip when its own power is not enough.

tiller with gear reducer

To understand what a gear reducer is, consider the structure of the transmission. It transfers torque from the engine to the wheels, and changes the speed and direction of the tiller. The transmission consists of a gearbox, differential, gearbox and clutch. Transmission units are gear, chain, belt or combine one or the other.
The gear transmission consists of bevel and spur gears (gear reducer). It is used on some models of cars and heavy tillers. The figure shows the gear transmission of the Tiller “Ugra” NMB-1, where a gear reducer is used.
