摘　　要：本文所述推力调心滚子轴承是钢铁行业中较常用的一种止推轴承。原轴承采用常规结构,在使用过程中由于衬套硬度不足,开放式的保持架爪极易磨损变形、断裂,导致轴承失效。特设计一种新型保持架,取消衬套,保持架采用一座和一盖用螺钉联接起来的结构,这样安装和拆卸可靠,提高了生产效率。The thrust self-aligning roller bearing described in this article is mainly used as a thrust bearing in the steel industry.The original bearing adopts a conventional structure.During use,the hardness of the bushing is insufficient,and the open cage claw is prone to wear,deformation and fracture,leading to bearing failure.A new type of structure is specially designed,with the elimination of bushings and the use of one seat and one cover for the cage,which are connected with screws,ensuring reliable installation and disassembly,and improving production efficiency.
