我厂J53—1000t双盘摩擦压力机,运行过程中发现螺杆与轮体间隙严重加大,6块切向键与轮体出现了很深的沟槽,使设备不能正常的运转。在讨论修复方案时,有两种意见:一是采用焊接方法,二是采用开口衬套法。焊接法因螺杆材料为35CrMo,焊接工艺性较复杂,加之本厂焊接条件差,故难以实现。为此,采用开口衬套法,衬套材料用45钢。修复前后结构见图示。
I plant J53-1000t double disc friction press, found during the operation of the screw and the wheel gap increased significantly, six tangential keys and the wheel appeared deep groove, the device can not operate normally. In discussing the repair program, there are two views: First, the use of welding methods, and second, the use of open bushing method. Welding method due to the screw material 35CrMo, welding process more complex, coupled with poor welding conditions factory, it is difficult to achieve. To this end, the use of open bushing method, the bushing material with 45 steel. Fix the structure before and after the icon.
