24000CA型调心滚子轴承实体保持架的改进设计

Design Improvement on Solid Gage of 24000CA Spherical Roller Bearings

采用实体保持架的 2 40 0 0CA系列调心滚子轴承若按常规方法设计 ,会使保持架无法装入 ,轴承无法合套。采用不减小保持架外径 ,只在 1 80°的对称位置上部分削减保持架外径的方法 ,既可保证保持架的强度 ,又不易掉滚子。

For the 24000CA series spherical roller bearing with solid cage, the cage can not be fitted in bearing if adopting universal design method. The proper method is that the partial cage diameter is cut out on 180°symmetry position without reduing outer diameter of the cage, which ensure the cage strength and prevent the rollers to drop from bearing.
