Abstract

Spherical plain bearings have the characteristics of self-adjusting and self-lubrication, they are widely used in defense, engineering and other fields. However, the spherical plain bearings are easy to fail in the process of work, and reasonable design seems to be very important. In order to save cost and reduce risk, the mechanical properties of spherical plain bearing are studied in the design process. According to a certain type of self-lubricating spherical plain bearings material properties, structure dimensions, working load and boundary conditions, the finite element model is established by using finite element method (FEM), then the finite element simulation analysis is carried out, the distribution of stress and deformation of spherical plain bearing is obtained, and the influence of grid division on the finite element results is analyzed. The results show that the maximum stress value occurs at a certain position in the outer ring and the maximum deformation occurs in contact position of the bearing line. Moreover, the simulation results are more practical and helpful to the design of bearing. The rationality of bearing design is verified by experiment, which provides a basis for bearing manufacturing enterprises..
