Frictional Behavior of Cage Guide Surface with Micro Textures
摘要
This paper focuses on the research of the microscopic topological texture of the guiding surface of integral-cage rolling bearings. By machining various micro-textures on circular pin-discs made of PEEK material and strip-shaped samples, tribological tests are carried out using a multifunctional friction and wear testing machine. The friction coefficients under different rotational speeds are measured, and the surface morphology after wear is observed. Based on the Computational Fluid Dynamics (CFD) method, a three-dimensional flow field model of the micro-textures is established to analyze their flow field characteristics. The research results show that the tribological properties of micro-textures with different configurations vary under different working conditions, providing a theoretical basis and data support for the optimized design of the rolling bearing cage.
