The needle roller bearing cage is a crucial element in maintaining the needle’s normal operation. The quality of the cage is strongly related to the needle roller bearing’s performance and live.
This research focuses on the cage models provided by the manufacturers. By using the finite element method with the computer aided engineering software, ANSYS, one can analyze the static stress of the cage structure. The analysis method consistent with the actual tensile experiments conducted by the manufacturers, and such analysis is used as an evaluation basis for further study. This research concentrates the meshing manners, level, displacement, and the stress distribution behavior of the cage, and provides a series of analysis method to break down the issues and understand the design of the cage structure. After a finite element analysis, the problem can be solved by the element size level 0.45 mm, and obtain a better in accuracy value. When the element performs even more delegate meshing in maximum stress value region, the result is as expected, an even better inaccuracy value.
