The invention discloses a train traction motor bearing life testing machine. On the basis of conventionally using a temperature sensor to obtain real-time temperature data corresponding to a test bearing in use, a vibration sensor capable of acquiring real-time vibration data of the test bearing is added, so two different types of real-time data can be used to jointly characterize the fault characteristic data corresponding to the test bearing under different faults, and at the same time, the trend of fault characteristic data changes under different fault degrees in a whole fault period can be detected, more accurate fault characteristic data with higher discrimination can be obtained to be subsequent fault criterion of the existence of a same fault. At the same time, in order to simulatean actual use scenario more real, two ends of a transmission shaft are arranged with two tested bearings, and the testing efficiency and simulation truth under a special use scenario can be significantly improved. 本申请公开了种列车牵
