How to Carry a Gearbox for a Trimmer?

The trimmer gearbox is the module that is needed for torque. The device includes one or more gears that rotate at high speed. The mechanism of this equipment is called a demultiplier, because it provides the conversion of the angular speed of rotation of the output shaft to its lower speed.

Manufacturers equip lawn mowers with gears that convert the low angular velocity of the input shaft to the output speed, which is higher. The engine with low power allows you to achieve the highest number of revolutions of the trimmer knife. The name of this option is the multiplier. A gasoline-powered trimmer is capable of flawlessly performing work related to lawn mowing and weed removal. The unit needs proper care, which involves the replacement of lubricants.

Types of gears and lubricants

Gearboxes according to the type of transmission are divided into the following varieties:

  1. Wave.
  2. Cylindrical.
  3. Planetary.
  4. Worm gears.
  5. Spiroid.
  6. Conical.
  7. Combined.

The main elements of cylindrical mechanisms are gear cylinders. Lawn mowers are very often equipped with modules of this type, worm types of gearboxes, etc. Are installed on trimmers. The transfer to them is carried out by means of a working screw. Planetary types of gears are distinguished by the coaxial arrangement of the shafts, while the bevel gears are crossed.

The gear transmission is able to work effectively only if there are no mechanical damage to the unit. For the device to function properly, normal temperature conditions must be created. Even the smallest distortions or overheating can cause jamming of the elements of the mechanism. This can lead to a stop of the trimmer, malfunction of the mechanism and serious consequences of its use, requiring repair of the unit parts.

Provide the necessary care for the equipment allows lubricants for gear trimmers, the types of which depend on their consistency:

Semi-liquid lubricants are characterized by the presence of a colloidal system containing various additives and additives. Grease is suitable for helical and gear transmission, so it is a universal option. The initial state of solid suspensions is ductile.

The grease of the gearbox of the lawn mowers is provided with a special composition specifically for gearboxes. Most lubricants are semi-fluid systems. When choosing the necessary lubricant, it is necessary to take into account the temperature regime for which the mixture is intended.

Gas trimmer reducer

The trimmer on gasoline can work qualitatively in any weather conditions. Electric models of lawn mowers are not able to meet the requirements of the owners of personal plots in this regard. Gasoline trimmers are characterized by increased power, which is associated with the possibility of processing large areas. Devices on gasoline sometimes also fail, which can happen for various reasons. Most often due to errors in the maintenance of the device.

For petrol trimmers, it is very important to periodically clean the fuel tank and change the oils. To increase the life of the electric trimmer, regular maintenance of various parts of the mechanism is carried out. Maintenance of equipment items should not take a lot of time, since it consists in the procedure of lubricating the rubbing parts before cleaning the filter.

Trim Grease Properties

In the production process of trimmer grease, special substances are used that meet environmental standards. After use, they are able to decompose in the environment without harm. Since the consistency of the composition has a level of increased viscosity, when heated, a decrease in lubricity in density occurs. This provides reliable protection of elements at maximum temperatures.

The productivity and duration of the trimmer is determined by the level of modern maintenance. Carrying out standard device care operations includes activities that are reduced to lubricating the gearbox and cleaning the air filter.

The filter cleaning process involves:

  • Removing the casing and removing the element;
  • Washing the casing with gasoline and drying;
  • Cleaning the filter insertion site from dust and oil.

After performing the above steps, it is necessary to ensure that the rod does not rotate in the sleeve. Then they go on to lubricate the gearbox, for which some gardeners use solid oil. This will require:

  1. Unscrew the plug.
  2. Fill the lubricant into the container.

To ensure long-term use of garden equipment allows special grease for the gearbox. Well-known manufacturers of trimmers, including Champion, Stihl, Makita, Husqvarna, produce their own products for the care of gardening equipment, which eliminates the possible problems associated with the search and selection of suitable lubricants.

The lubricant must be changed in the gearbox with a frequency of 50 hours of operation of the unit as a whole. To find out more accurate data for a particular model, you can see its technical passport. Care is necessary for the trimmer shaft, so it should be cleaned and greased liberally immediately after purchase.

How to lubricate the gearbox

Before the first start of the trimmer, a number of sequential actions are performed:

  1. Inspect the gearbox.
  2. Prepare the correct fuel mixture.

The implementation of these actions is recommended not only for new devices, but also in the preparation of old units for the next season after storage. If grease is available in small quantities or is absent, this leads to increased friction of the gear part of the gearbox. Since it should work at fairly high speeds, the gearbox must be checked regularly before starting the petrol trimmer.

If the gears overheat, this leads to the mowing gear reducer malfunctioning. To prevent this, start and break-in trimmer start with inspection and lubrication of the bevel gear. To fill the oil in the gearbox of the gas spit before starting it:

  1. Remove the screw that is located on the bend of the gear housing.
  2. Extrude Litol grease in an amount of 1-2 ml.
  3. Tighten the screw.

Grease is added to the gearbox of the gas trimmer every 8-10 hours of operation of the unit.

For this, a special technological hole is provided in the housing. Inspect the module for lubrication both before the first and each subsequent use of the equipment.

Conclusion

You can purchase a special composition for the gearbox in the form of tubes having a long feed spout, the diameter of which must match the size of the hole. This is not always the case, as models from different manufacturers differ in their diameter of the hole.

In this case, summer residents should prefer the use of a medical syringe, which is convenient in that it allows you to accurately measure a portion of the mixture.
