High-speed train axle box bearing dynamic test equipment

Abstract

The invention discloses high-speed train axle box bearing dynamic test equipment which comprises a rack and a mounting seat. Two connecting seats are arranged on the bottom surface of the rack, vibration loaders are respectively arranged on the two connecting seats in a swinging manner, and the output ends of the vibration loaders are arranged along the height direction. The mounting seat is rotatably connected with the output ends of the vibration loaders through hinges. The rack is provided with a test bench in the circumferential direction of the mounting seat. The mounting seat is rotatably provided with a rotating main shaft, and mounting grooves used for mounting a high-speed train axle box are formed in the two ends of the rotating main shaft. The test bench is provided with a driving motor, An axial loader is further arranged between the mounting seat and the test bench. Cushioning frames used for being connected with the high-speed train axle box are arranged at the positions, corresponding to the mounting grooves, of the two ends of the rotating main shaft, and the cushioning frames are connected with the rack through cushioning springs. The equipment can effectively simulate the actual working condition of a high-speed train axle box bearing, effectively detect the related use parameters of the axle box bearing, and improve the detection accuracy.

Description

technical field [0001] The invention relates to the technical field of bearing detection, in particular to dynamic testing equipment for high-speed rail axle box bearings. Background technique [0002] At present, many high-speed rail axle box bearing tests are carried out by static loading, and no environmental factors are added. This has caused many products to pass the test in the test stage, but the products cannot meet the requirements when they are actually loaded into the car. The high-speed rail is subjected to different load conditions when entering and leaving the station, high-speed straight, curves, branch roads, entering and leaving the warehouse, and the external environment changes greatly during the operation of the high-speed rail. These are not considered by traditional tests. At present, there is also a lack of devices to verify the performance indicators and service life of the axle box bearings under actual working conditions, and there is also a lack o...

AI Technical Summary

Problems solved by technology

At present, there is also a lack of devices to verify the performance indicators and service life of the axle box bearings under actual working conditions, and there is also a lack of testing equipment to verify whether the bearings can reach the specified service life under actual working conditions or enhanced working conditions. At the same time There is also no relevant detection equipment for the temperature change of the bearing during operation and the influence of different greases on the use of the axle box bearing
