Description

Technical Field

[0001] The utility model relates to the technical field of light rail locomotives, in particular to a wear resistance detection device for gear box castings of light rail locomotives. Background Technique

[0002] A light rail locomotive is a type of urban rail transit line system and is also the most rapidly developing rail transit form in the world today. The locomotive weight and passenger capacity of the light rail are smaller than those of ordinary trains, so it is called "light rail". Urban light rail has the advantages of large transportation capacity, high speed, low pollution, low energy consumption, punctual operation, and high safety. Urban light rail, together with subway, urban railway and other rail transit forms, constitutes the urban rapid rail transit system.

[0003] Among them, for the gear box castings of light rail locomotives, after the design and sample processing are completed, relevant technical parameters need to be tested. The wear resistance can determine the service life of the castings, so the wear resistance is a relatively important parameter. At present, for the wear resistance experiment, mechanical extrusion is required under two different materials, and then one material is made to perform continuous circular motion. Since the frictional force is directly proportional to both the friction coefficient and the normal pressure, the mechanical extrusion directly affects the magnitude of the frictional force, thereby affecting the accuracy of the experimental data. At the same time, the continuous circular motion is different from the reciprocating friction in the actual situation, so it will lead to the distortion of the wear resistance test.
