Tungsten Disulfide Used in Automotive Gear Lubrication

Tungsten disulfide is a kind of lubricating material with high quality. It can be used in automotive gear lubrication to speed up the heat dissipation and reduce the wear on the gear surface. The lubrication treatment with tungsten disulfide is usually simple, which make the material an ideal choice for the automotive gear lubrication.

Spur gear and helical gear are two common types of automotive gear. They have advantages and disadvantages respectively, which is as follows:

1. Spur Gear

Advantages: High transmission efficiency. The meshing process of the gear is short.

Disadvantages: Poor transmission stability and large noise.

2. Helical Gear

Advantages: Good transmission stability, good bearing capacity and small noise. The long transmission of the gear is directly involved with these advantages.

Disadvantages: Complex structure. The gear is usually equipped with thrust bearing.

No matter which type the gear is, there are relative sliding and friction during the transmission process, which leads to the problems of wear on gear surface and the increasing of power consumption. If the gear becomes too worn, the operation of vehicle may be affected. In order to reduce the friction, appropriate lubricating material should be taken.

Tungsten disulfide is the preferred choice. This kind of material not only has good lubricating performance, but has excellent high temperature and extreme pressure performance. And excellent corrosion resistance is also an important performance of tungsten disulfide.

This kind of lubricating material is suitable for the condition of high temperature, high pressure and heavy load, which is the working environment of automotive gear. Morever, the lubrication treatment of tungsten disulfide is simple. The material can be directly applied on the gear surface to reduce the wear and speed up the heat dissipation. As tungsten disulfide can provide good and long-term lubrication, it is an ideal material for the lubrication of automotive gear.
