有的东方红—60(75)拖拉机主离合器分离杆螺栓经常折断。究其折断原因,要从分离杆螺栓的作用谈起:当主离合器进行分离时,分离轴承通过分离杠杆的作用,使分离杆螺栓移动,螺栓拉动压盘,压缩12根主离合器弹簧。使压盘和从动盘摩擦片分开,从而使离合器分离。每次分离,压盘和压盘传动销都有相对摩 Some Dongfanghong-60 (75) tractor main clutch separation rod bolts often break. The reasons for the break, from the role of the separation rod to talk about: When the main clutch for separation, the separation of the role of the bearing lever through the separation lever to move the separation rod bolts, bolts pull the pressure plate, compressing the 12 main clutch spring. The platen and the driven disc friction plate are separated so that the clutch is disengaged. Each separation, pressure plate and pressure plate drive pin has relative friction
