摘　　要：针对1580精轧F7机架辊新品上机试车启动力矩大、运行过程中存在冲击负荷损坏传动轴联轴器、负荷突变使电动机发热烧坏等问题,对机架辊传动轴进行了改造,同时对轴承座内部装配进行精度改良,降低机架辊的启动力矩,减小运转过程产生的摩擦力,优化机架辊更换后的位置精度,从而提高机架辊的运行稳定性,延长使用寿命,获得了良好的应用效果。The stand roll of bayuquan 1580 finishing mill is located at the exit of the mill,its transmission shaft is directly conected with the motor through the archway.Its structure design is compact,the working space is narrow and the working environment is bad.It is difficult to carry out routine spot check and maintenance,poor stability and frequent accidents.The coaxiality deviation between the motor and the roller table is large,which is difficult to be aligned,resulting in the failure of the anchor bolt and the fracture of the motor spindle.The gap between the rotating parts of the frame roller is smallthe starting torque of the motor is small,and the starting torque of the roller table during the maintenance and test run is large,which leads to the motor overload.Therefor,it is urgent to solve the running stability of the stand roller device completely.
