How can the reducer gear avoid friction during operation?

Most gear reducers in construction machinery do not run at high speed, but intermittently. When stopping the oil film, it is impossible to form an oil film, which is in dry friction state. During the normal operation of gear, it is difficult to form hydrodynamic lubrication or elastohydrodynamic lubrication due to the low linear speed of gear of reducer motor. Therefore, under normal conditions, the polar molecules adsorbed on the lubricating oil are separated and the composition layer is relatively firm.

When the reducer gear mesh in the sliding area, the gear face bears fluctuating Hertz stress, and on the other hand, it also bears sliding friction in the opposite direction of the sliding speed. The friction size changes constantly. Under their joint action, this process destroys the existence of the oil film and has a great impact on the surface condition of the reducer gear.
