Crawler excavator is a widely used construction machinery. Its transmission device is composed of Hydraulic motor And planetary gear reducer Travel motor 。

According to the actual inspection and maintenance experience of the excavator, it is found that the joint of the motor output shaft and the seal of the framework oil seal is particularly easy to wear. Drive hydraulic motor After the wear reaches a certain degree, the oil in the hydraulic motor and reducer will flow in tandem. Since there are many oil dirt and impurities in the planetary reducer, the oil in tandem will pollute the plunger motor and damage the hydraulic motor.

However, the output shaft of the hydraulic motor of the crawler excavator currently used in the market is of a single structure, Hydraulic motor manufacturer The entire output shaft must be replaced.
