Abstract: Because of that the permanent magnetic bearing (PMB) has the advantage of no wear, low cost and simple structure, the industrial design concept of PMB has been put forward in this paper. Radial and axial permanent magnetic levitation technology has been studied, and the aforementioned design is done based on these two kinds of technologies. During the experiments on the mechanical characteristics of PMBs, the capacity and stiffness of the bearings are researched.

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.
