拆卸内燃机车轮对轴上轴承环和迷宫式密封圈是修理工作中的一项繁重操作,并有一系列特点。这与被拆零件的不同结构、过盈量以及为重新利用它们力求保持配合表面必需的质量和被拆零件材料的物理机械性能有关。迄今拆卸上述零件所采用的方法和设备在大多数情况下都不能保证满足这些要求。例如,很多企业为拆卸这些零件而采用的煤气喷嘴往往使被拆零件过热,并导致工作场地严重污染和烟雾。现有的各种感应拆卸器只用来拆卸一个零件。拆卸轴上一组压装零件时,每一个后拆零件都必须加热到比前拆 Removal of the wheel on the shaft of the bearing on the shaft and the labyrinth seal ring is a heavy repair operation, and a series of features. This is related to the different structures of disassembled parts, the amount of interference, and the re-use of them to maintain the necessary quality of the mating surfaces and the physical and mechanical properties of the disassembled parts. To date, the methods and equipment used to disassemble these parts have not, in most cases, guaranteed to meet these requirements. For example, the gas nozzles used by many businesses to disassemble these components often overheat disassembled parts and cause serious workplace pollution and smoke. The existing variety of inductive puller is only used to disassemble a part. When removing a set of press-fit parts on the shaft, each rear part must be heated to a front split
