我矿JD-40型调度绞车的小行垦齿轮架键槽易损坏,修理时拆装轴头处的轴用弹性挡圈比较困难.为此我们设计了简易轴用弹性挡圈装配装置(见图1).小行星齿轮架2装在主轴1上,主轴轴头处需装限位挡圈7.把锥度套8用两根螺栓9固定在圆柱形轴头上,同时旋紧螺母5,然后在锥度套8的圆锥处套上挡圈7和压套6,旋紧螺母4,挡圈便沿着锥面滑行,直径逐渐胀大、瞬间卡入挡圈槽中.锥度套大端的四孔深度h等于挡圈槽至轴端面的距离l,压套6内腔的长度大于锥度套8的长度.此方法装配迅速,效果很好.
I mine JD-40-type scheduling winch small reclamation gear rack keyway easily damaged, the shaft head at the time of disassembly and assembly of the elastic ring is more difficult.To this end, we designed a simple shaft retaining ring assembly device (see Figure 1) The planetary gear carrier 2 mounted on the spindle 1, the spindle shaft head to be installed limit retaining ring 7. The taper sleeve 8 with two bolts 9 is fixed to the cylindrical shaft, while tightening the nut 5, and then The conical sleeve taper sleeve set 7 and the pressure sleeve 6, tighten the nut 4, the ring along the taper slide, the diameter gradually swollen, snapped snap ring groove. Taper four large end of the hole Depth h is equal to the distance from the ring groove to the shaft end face l, the length of the inner cavity of the pressure sleeve 6 is greater than the length of the taper sleeve 8. This method is quick to assemble and works well.
