Tungsten Disulfide Used in Connecting Rod Lubrication

With good lubricating performance and excellent extreme pressure resistance, tungsten disulfide is an ideal material for connecting rod lubrication. This kind of material works stably under the condition of high temperature and heavy load. It can prolong the service life of connecting rod effectively.

Connecting rod is a functional part connecting the piston and the crankshaft. It consists of three parts: the connecting rod little end, the connecting rod big end and the connecting rod body. Among them, the connecting little end is connected with the piston through the piston pin, and the connecting rod big end is connected with the connecting rod journal of the crankshaft.

Connecting rod transmits the gas pressure which the piston bears to the crankshaft, transforming the reciprocating motion of the piston into the rotating motion of the crankshaft. It is an essential part in the automobile engine.

During the operation of the engine, connecting rod is subjected to alternating loads such as compression and tension. It works under the condition of high temperature, high pressure and heavy load. Therefore, it is prone to deformation and wear. In serious cases, the connecting rod body or the connecting rod bolt may be broken, which leads to the scrap of the engine.

As a kind of lubricating material with excellent performance, tungsten disulfide can be used for connecting rod lubrication, effectively improving the service life of the part. It has the following performance

1. Good lubricating performance.

Tungsten disulfide has low friction coefficient, which is only 0.03.

2. Excellent high temperature and extreme pressure resistance.

Tungsten disulfide works stably under the condition of high temperature, high pressure and heavy load, which is the working environment of connecting rod.

3. Wear resistance.

Tungsten disulfide can form a dense protective film of tungsten trioxide at high temperature. It can reduce the wear effectively.

4. Corrosion resistance.

Tungsten disulfide can provide maximum corrosion protection for connecting rod.
