Tungsten Disulfide for Crankshaft Lubrication

Tungsten disulfide with good lubricating performance works stably under the condition of high temperature, high speed and heavy load, which is the working environment of crankshaft. Therefore, tungsten disulfide is an ideal material for crankshaft lubrication.

Crankshaft is the most important part of the engine. It bears the force from the connecting rod and drives the other parts, by turning the force into torque. The force condition of crankshaft is very complex. It is not only affected by the centrifugal force of rotating mass, but also by the joint action of the cyclically-changing gas force and reciprocating inertia force. Crankshaft withstands the bending and torsional cyclic loading.

To ensure the reliable operation, crankshaft should have enough intensity and strong. And the journal surface should be wear-resistant. Moreover, the lubrication of crankshaft is extremely essential.

Good lubrication of crankshaft not only reduces the wear, but also smooths the operation between crankshaft and other parts. It is very important for the long-term stable driving of the car. In order to get good lubrication effect, appropriate lubricating material is the key.

As a new kind of solid lubricating material, tungsten disulfide has many good properties, such as good lubricating performance, excellent high temperature resistance and good extreme pressure resistance. And corrosion resistance is also an important performance of this kind of material. Under the condition of high speed, high temperature and heavy load, which is the working environment of crankshaft, tungsten disulfide can still provide good lubrication for crankshaft. When it is applied in the crankshaft lubrication, it can reduce the wear on crankshaft surface to the greatest extent and prolong the service life of the crankshaft effectively, which makes the driving process of vehicles smoother. Therefore, tungsten disulfide has high application value in crankshaft lubrication that it can provide high-quality lubrication for the part.
