Cavitation and slip performance analysis of dynamically loaded sleeve bearing

The generalized Reynolds equation of dynamically loaded sleeve bearing is established based on mass conservation boundary condition and wall-slip effect. The cavitation migration and flow velocity of spiral oil wedge bearing for different times are computed, using the finite difference method by solving the Reynolds equation of four slip states with cavitation effect. The results show that the cavitation area with cavitation effect and wall slip decreases compared to the cavitation area without regard to cavitation effect and wall slip. As time goes, the slip location at the surface of axis and sleeve moves generally along the rotation direction of axis, and the region of slip changes.
