Analysis of Failure Effect of Cage Thickness on Spherical Roller Bearings

Abstract

Spherical roller bearings are important parts of high-frequency crushers. Using the finite element analysis software to carry on the transient dynamics analysis to the bearing obtains the bearing deformation, the pressure and so on characteristis. Then, by contrasting and analysising, it is found that under pure radial load, radial load and axial load mixed force, influence of cage thickness on bearing performance. The results show that the thickness of the cage has little effect on the deformation of the bearing under pure radial load. Under the combined action of the radial load and the axial load, the radial deformation of the bearing decreases compared with the pure radial load. The deformation of the cage under the mixed load is increased than that under the radial load.
