Influence of different oil flow directions on the friction performance of asymmetric structures in heavy load hydraulic friction pairs

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