250B轴承环扩孔机改造初探

Preliminary discussion on transformation for 250B bearing ring rolling machine

经过对设备的滑动导轨、汽缸尺寸及结构、碾压宽度、传动轴结构等部分进行改造,使该设备的结构更加合理,加工范围增加,降低成本,故障率低,使用寿命延长。

Through the transformation of sliding guideway, cylinder size and structure, rolling width ,driveshaft structure and other parts of the equipment, it has become more rational and had a larger range of production so as to reduce the cost and error rate and extend its service life.
