Abstract: 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.

Abstract: According to the working requirement of large-scale cross roller slewing bearing used in special propeller, an optimal design model which includes objective function, optimization variables and constraints is established, and uses genetic toolbox of the Matlab software to solve the mathematical model. An example shows that the bearing’s life is improved significantly by the optimization. It indicates that the optimization design has some guidance significance in the design process of the slewing bearing.
