山东黄金集团金洲公司有1台2JTP-1200型矿井提升绞车,于1998年安装在主井-335 m中段,至今已连续运行10年。2008年6月设备巡检时发现绞车电机端联轴器有异常响声,停车后检查发现电机输出轴与联轴器间隙较大,且联轴器沿电机输出轴有圆周方向位移。 Shandong Gold Group Jinzhou Company has a 2JTP-1200 mine hoisting winch, which was installed in the middle section of the main shaft at 335 m in 1998 and has been in continuous operation for 10 years. In June 2008, when the equipment was inspected, it was found that there was an abnormal noise on the motor end coupling of the winch. After the parking check, the clearance between the motor output shaft and the coupling was found to be large, and the coupling was displaced circumferentially along the output shaft of the motor.
