摘　　要：热连轧生产线同类窜辊装置中均存在窜辊缸活塞杆与调心头脱开的现象,通过对窜辊装置中窜辊缸活塞杆与调心头的联接方式进行改造,由螺纹联接改为过盈联接后,解决了这一问题,本文详细介绍了活塞杆与调心头过盈联接的理论计算及热装工艺。As for the same kind of roll shifting mechanisms of hot continuous rolling production line, all the piston rods of the roll shifting cylinder might disconnect from the center adjusting head during the service. The solution to this problem is that interference fit connection is used instead of thread connection for the connection method of the roll shifting cylinder piston rod and center adjusting head. Theoretical calculation of the interference fit connection and shrink fit assembly process have been described in detail.

关 键 词：窜辊缸活塞杆 调心头 过盈量 热装工艺
