Abstract

Provided is a cylindrical gearbox mechanical closed test bench suitable for any center distance. If any of a model of a motor, operation speed and a wheel diameter of a gearbox is different from that of another gear box, the models or transmission ratios of the gearboxes are different and accordingly center distances of the gearboxes are different; different connection gearboxes are needed in order to test the gearboxes with different cylindrical gear center distances. The mechanical closed test bench of the novel structure is composed of two cylindrical gearboxes, two connection cylindrical gearboxes, a hydraulic torque loader, a drive motor, two torque meter, a bearing block, a coupler, a shaft, a universal shaft and the like, wherein the two cylindrical gearboxes are completely the same and used for tests and include the tested gearbox and the accompanying tested gearbox, and the two connection cylindrical gearboxes are completely the same. The cylindrical gearbox mechanical closed test bench has advantages of other mechanical closed load test benches, can be suitable for any change of the center distance of the tested gearbox automatically, and has the advantages of being easy and convenient to use, safe and reliable.

Description

Technical field [0001] The design of the invention is a mechanical closed test bench for a cylindrical gear box adapting to any center distance. On railway locomotives and bullet trains, the gearbox increases the torque generated by the motor and directly transmits it to the wheel set, so the working conditions are poor. In order to check whether the gearbox meets the design goals, to verify its reliability, and to accumulate experience for future design and development, it is necessary to test the trial-produced new gearbox. This new structure successfully solves the problem of replacing different connecting gearboxes due to different gearbox models or changes in the center distance of the gears, and has the characteristics of simple structure, safety and reliability. Background technique [0002] Most railway locomotives and bullet trains use cylindrical gearboxes, which increase the torque generated by the motor and directly transmit it to the wheelset to generate tracti...
