设备检修过程中，经常遇到轴承的拆卸问题，一般都采用轴承拉出器和紫铜棒撞击的方法。轴承拉出器用爪拉轴承的外环，通过滚动体把力传递给内环，把轴承从轴上拆卸下来。这种方法对轴承有一定的损伤，而且不适于轴承位置离轴端距离大的情况，用紫铜棒撞击轴承方法对轴承的损伤 Equipment maintenance process, often encounter the problem of bearing disassembly, the general method of using the bearing puller and copper rods hit. The outer ring of the claw bearing for the puller of the bearing is used to transmit the force to the inner ring through the rolling element and the bearing is detached from the shaft. This method has some damage to the bearings, but not suitable for bearing the position away from the end of a large distance from the case, the method of bearing a copper rod impact on the bearing damage
