China Wholesale Single Row Bearing for Car and Machine Part

The load distribution of the roller along the contact line is given, which lays a theoretical foundation for calculating the fatigue life and structural parameters of the roller bearing clutch. The torsional stiffness of the roller bearing clutch is nonlinear, indicating that the system has complex nonlinear dynamic behavior. The natural frequency of the system in the engaged state is given, providing a theoretical basis for studying the resonance and the first critical speed of the system.

It is generally believed that rolling friction torque is related to contact surface roughness, elastic hysteresis, adhesion effects, and differential sliding. Matsuhara pointed out that when the roughness of the contact surface between two objects is at 1 μ Below m, there is almost no effect on the friction torque, so the effect of surface roughness can be ignored. It is believed that the rolling friction torque in overrunning clutches mainly comes from elastic hysteresis and adhesion effects, while the effects of micro sliding and plastic hysteresis are relatively small and can be ignored. Holling also has the same view, so only the power consumption caused by elastic hysteresis and adhesion effects is analyzed and studied, regardless of the impact of factors such as contact surface roughness and differential sliding.
