摘　　要：本文通过实际案例,说明活塞杆与活塞的连接处由于预紧力过大,会导致活塞杆与活塞连接的部分提前发生疲劳失效,针对该情况,本文提供了三种活塞杆与活塞连接的结构形式,并说明其安装方法。In this paper,through the actual case shows that because of the excessive pre--tightening force at the connection of piston rod and piston,it will cause this part fatigue failure earlier. In view of this situation, this paper provides three kinds of structures of the connection between pisien rod and the piston,and explains its installation method.

关 键 词：活塞杆 活塞 预紧力 疲劳失效
