The company has developed a test equipment for rotating bending fatigue of train axles, which consists of: an electric spindle controlled by the data acquisition and control system is installed on the base, and the electric spindle is connected with the spring collet through the coupling and the axle box filled with cooling oil; The spring collet holds the axle of the axle sample; There are speed sensors and revolution sensors beside the coupling; The wheel of the axle sample is in contact with the driven wheel below, the shaft of the driven wheel is installed on the driven wheel support, and the guide sleeve of the driven wheel support is sleeved on the guide post of the sensor base; The threaded hole of the pressure sensor of the sensor base is connected with the adjusting column, the upper end of the adjusting column is in contact with the lower surface of the bottom plate of the driven wheel support, and the middle of the adjusting column is provided with a self-locking threaded ring. The test equipment can easily simulate the rotary bending fatigue damage of train axles under complex alternating loads, so as to improve the fatigue damage resistance of axles, better protect axles, and provide more reliable and accurate test basis.
