热轧粗轧机万向接轴故障分析与改进

Failure Analysis and Improvement on the Universal Joint Shaft of Hot Rolling Roughing Mill

针对天铁热轧生产线粗轧机主传动万向接轴存在的接轴晃动大,平衡支架晃动,十字包频繁损坏等故障,通过改造十字万向节扁头孔,定期测量并更换工作辊和支撑辊衬板窗口尺寸,定期检修轧机平衡系统,改进轴承润滑制度等措施,消除了各种故障,延长了万向接轴的使用寿命,降低了生产成本,保证了设备的正常运行。

Aiming at the failure of the big swing of joint shaft,the moving of balance bracket and the frequent damage of cross package at main drive universal joint shaft of Tiantie hot rolling production line roughing mill,measures were taken of modifying the flat head hole of cross universal joint,periodically measuring and exchanging the liner window size of work roll and back up roll,periodically inspecting mill balancing system and improving bearing lubrication system to eliminate all kinds of fault,prolong the service life of universal joint shaft,reduce production cost and ensure the normal operation of the equipment.
