摘　　要：分析带牙口满装滚针轴承结构和影响装配高的主要因素,结合生产实践,在内圈热处理后增加牙口硬车工序,实例分析表明,工艺改进有效保证了该类轴承的装配高,提高了装配合格率。The structure of full complement needle roller bearings with spigot and main factors affecting assembly height are analyzed. Combining with production practice, the hard turning process for spigot is increased after heat treatment of inner rings. The actual example analysis shows that the process improvement effectively ensures the assembly height of bearings, and the qualification rate of assembly is improved.
