Description
Summary:Textures have obvious anti-friction and anti-wear effects, but effective textures often have complex and asymmetric characteristics. Because of the texture’s directional lubrication effect and fluid diode effect, different oil flow directions influence the friction reduction effect of asymmetric texture. Simulations and test methods are used to characterize these effects, and the friction coefficient and wear amount are used as evaluation methods to determine the optimal oil flow direction of asymmetric textures. The results show that an appropriate oil flow direction can significantly change the texture’s friction-reducing ability. The friction reduction efficiency of the texture is highest when the angle between the oil flow direction and the inflow edge of the texture is 60°–90°. When the angle between the oil flow direction and the inflow edge of the texture is 0°–30°, the texture’s anti-friction effect and efficiency are weakened.
