  How to disassemble the broken axle of the wheel of a mine electric locomotive   The maintenance of the broken motor axle is a tricky thing for most small and medium mines. Because the assembly of the axle and the shaft is an interference fit, it is difficult to disassemble and disassemble intact and maintain accuracy.   1. Disassembly of the axle The matching interference between the motor wheel shaft and the wheel shaft is large. If a large press is used to force the broken shaft remaining in the shaft to be forced out, it is easy to destroy the wheel shaft size. Moreover, small and medium-sized mine repair plants generally do not have large presses. . In order to facilitate the disassembly of the shaft without damaging the size of the wheel, and to ensure the accuracy and roughness of the wheel, drilling can be used. The specific operation is as follows: Use a drill bit with a price of 18-22~, drill three holes side by side along the diameter direction at the outer shaft end of the
