前言

本标准是对JB/T7934—95《胀紧联结套型式与基本尺寸》的修订。

本标准与JB/T7934—95相比，主要技术内容变化如下：

——增加了Z6~Z2015种型式；

——取消了附录A的表A5~表A9；

——采用按轮毂材质屈服极限计算轮毂外径公式；

——将附录B改为附录C，附录C为Z1型胀紧联结套的联结设计要点。

本标准自实施之日起代替JB/T7934—95。

本标准的附录A、附录B和附录C都是提示的附录。

本标准由冶金设备标准化技术委员会提出并归口。

本标准起草单位：中国第二重型机械集团公司、德阳二重基础件厂。

本标准主要起草人：赵秉厚、赵保宇、赵光发。

本标准于1986年2月首次发布。
