Study on Tribological Characteristics of Textured Surface under Convergent Oil Film Gap

Under the condition of convergence, a textured non-parallel 2D slider bearing model was established, and tribological properties surface under convergence gap were numerically studied with load-carrying capacity as an indicator. Firstly, whether ratio parameter can accurately characterize joint effects film thickness difference oil on verified, non-textured studied, respectively. The results show that efficiency improving structure first increases then decreases increase thickness. In case large difference, texture will reduce capacity. addition, depth, width, sliding velocity are also studied. particular, optimal width to maximize exists.
