圆柱滚子轴承青铜保持架加工工艺改进

摘要

针对圆柱滚子轴承青铜保持架兜孔侧梁处锁口采用滚压成形时出现微裂纹的问题，通过试验，分析保持架机加工对工件表面冷作硬化的影响，以及去应力退火对工件硬度、塑性成形性能的改善作用，确定增加去应力退火工序可以保证保持架锁口的加工质量。%Aiming at the problem of microcracking in the side of the pocket lock hole of the bronze cage of cylindrical roller bearings in roll forming,the effect of the cage machining on the cold hardening of the workpiece surface,and the effect of stress relief annealing on the hardness and forming performance are analyzed by experiments,and stress relief annealing is implemented to guarantee the processing quality of the cage lock hole.
