“…The coefficient of friction decreases with the decrease of roughness, and the coefficient of friction also decreases with the increase of electrical contact resistance. Since the boundary film formed by lubricating oil has a great influence on reducing the friction coefficient, Kato et al [2][3] also used theoretical models and experimental methods to study the dependence of the load and boundary film on the friction coefficient. Tonazzi et al [4] proposed that grease can protect the bearing contact surface, and the plastic deformation under the steel ball surface is the main reason of bearing damage under high radial load and oscillating motion.…”

To transfer more power and use it in a heavy load environment, the contact surface between the ball and the track must bear great stress. The temperature always rises due to friction, which is more likely to cause problems of material deformation and fatigue failure. As a result, it will be a key technology to maintain a certain lubricating effect of the transmission components under the environment of heavy load and temperature rise. Through the analysis of friction coefficient and electrical contact resistance, the greases are used to test the lubricating effect of the transmission elements under the heavy load condition. The results will be helpful for the industry to use heavy load greases as a reference.
