Abstract

The present invention discloses a high-temperature environment high-speed train wheel axle wearing simulation box. Fans, a pressure shaft, a pressure plate and a gear box are located at the internal portion of the box body; the fans are located at two sides of the box body and configured to perform heating of the internal portion of the box body, a fan heating mode can ensure the uniform temperature in the box body and can have a drying effect; the pressure plate is connected with the pressure shaft and is located above the gear box; the pressure shaft is connected with an external force applying device and configured to apply pressure to the wheel axle to be measured, and the external force applying device is connected with the pressure shaft, the pressure shaft and the pressure plate areemployed to apply pressure to the wheel axle to be measured to simulate the load of the wheel axle in the actual operation process; and the gear box drives the wheel axle to be measured to rotate soas to simulate the operation of the wheel axle. The simulation box provided by the embodiment of the invention is simple in structure, can simulate the extreme high-temperature weather and the actualcondition that the parts of the wheel axle are worn and can determine the optimal selection materials of the parts so as to improve the operation efficiency of the high-speed train and reduce the maintenance cost.

Description

technical field [0001] The invention relates to a wheel shaft wear simulation device, in particular to a high-speed train wheel shaft wear simulation box in a high-heat environment. Background technique [0002] In different regions, the running environment of trains is complex. In some extreme environments, such as high-cold dry environment, high-heat dry environment, high-heat and humid environment, etc., parts of various parts of the train need to be able to withstand different climatic environments. In related technologies, the driving areas of domestic high-speed trains hardly involve the above-mentioned extreme environments, and it is impossible to determine whether the parts used in existing trains can operate normally under extreme conditions. Contents of the invention [0003] In view of this, the embodiment of the present invention provides an experimental device for simulating extreme environment and wear degree of raw materials used in train parts. [0004] I...
