Ring Strength Analysis of Driving Wheel Bearing Based on Ultimate Strength Design Methods

摘要

According to the "Ultimate strength design methods" of rolling bearing and from the whole strength of ring, the paper has analyzed the relationship between ring deformation and strength. It is shown that the local deformation of ring is the main factors affecting the collar strength. Programmed Matlab procedures, the minimum limit of ring thickness of the driving wheel bearing is studied, and a reasonable explanation of outer-ring fracture is given.
