前言

本标准非等效采用ISO2982–1∶1995《滚动轴承附件锥形衬套》。标准中补充了国际标准中没

有的技术条件。

本标准是对JB/T7919.1—95《滚动轴承附件退卸套外形尺寸》和JB/T7919.7—95《滚动轴承

附件锥形衬套、锁紧螺母和锁紧垫圈技术条件》的修订。

本标准与JB/T7919.1—95、JB/T7919.7—95相比，主要作了以下修订：

——将JB/T7919.1的尺寸与JB/T7919.7相关内容的技术条件合并；

——扩大了锥度1∶12的退卸衬套AH30、AH31、AH32系列尺寸范围，增加了AH39系列及锥度

1∶3的AH240、AH241系列；

——部分型号的退卸衬套螺纹尺寸改变，其代号也随之改变；

——补充了扩大的尺寸段的公差。

本标准自实施之日起代替JB/T7919.1—95、JB/T7919.7—95（部分）。

本标准的附录A是标准的附录。

本标准由全国滚动轴承标准化技术委员会提出并归口。

本标准起草单位：洛阳轴承研究所。

本标准主要起草人：李飞雪、陈原、郭宝霞。
