Abstract

A large number of cracks were found in the gear box of high speed train in practical applications. According to the line test, the weak position was got and the reason of cracks was researched. The influence of the different vibration source on the weak part was studied by means of vibration spectrum analysis. The vibration transfer characteristics of 4 kinds of gear box are studied and the vibration transfer law was analysed. The results show that: the gearbox vibration is mainly influenced by the vibration of the axle box, the vibration of the motor and the gear meshing vibration. The low frequency vibration of the gear box is mainly from the axle box vibration, and the high frequency vibration is mainly influenced by the gear meshing vibration.
