Problems solved by technology

[0002] In order to increase the operating speed and improve the quality of high-speed operation, some railway high-speed trains adopt the motor body suspension method, and use the bevel gearbox to increase the torque generated by the motor and directly transmit it to the wheel set to generate traction. The working conditions of the gearbox are harsh.

specific Embodiment approach

[0010] The specific implementation is: taking the tested gearbox 3 as the core, first arrange the pinion shafts of the tested gearbox 3 and the companion gearbox 13 face to face, and pass the torque meter 1 (part number 4), the coupling and the bearing seat Two (item number 14) connect the pinion shafts of the two; the two symmetrical output shafts of the connecting gearbox 8 are respectively connected to the two large gear shafts of the conical gearbox used in the test, and the large gear shaft of the tested gearbox is connected to The output shaft of the gearbox is connected to the bearing seat, another torque meter 2 (key 5), coupling 1 (key 6) and hydraulic torque loader 7 in turn, and test the large gear shaft of the gear box with the connecting gear box The output shafts are connected with the bearing seat, the cardan shaft 12 and the coupling three (part number 11) in sequence; the two torque meters connected to the shaft ends of the large and small gears of the tested ge...

Abstract

Provided is a universal bevel gear case mechanically-closed test stand. If any one of motor type, operation speed and gear diameter are different, the type or transmission ratio of a gear case is also different, and the universal bevel gear case mechanically-closed test stand can adapt to bevel gear cases different in gear module and transmission ratio. The universal bevel gear case mechanically-closed test stand consists of two completely-identical bevel gear cases for testing, one connecting cylindrical gear case centro-symmetric completely, one hydraulic torque loader, one drive motor, two torque meters, bearing seats, a coupler, a shaft, a universal shaft and the like, wherein the bevel gear cases include one tested gear case and one assistant gear case. The universal bevel gear case mechanically-closed test stand has the advantages of other mechanically-closed loading test stands, meanwhile can automatically adapt to testing of the bevel gear cases different in gear module and transmission ratio and has the advantages of being simple and convenient to use, safe and reliable.

Description

Technical field [0001] The design of the invention is a universal mechanical closed test bench for bevel gearboxes. On railway locomotives and high-speed trains, the gearbox increases the torque generated by the motor and directly transmits it to the wheelset, which results in poor working conditions. In order to verify whether the gearbox reaches the design goal, it is necessary to verify its reliability, and to accumulate experience for future design and development, it is necessary to test the new gearbox that is trial-produced. This new structure successfully solves the test problem of the bevel gearbox mechanical closed test bench with any gear modulus and transmission ratio, and has the characteristics of simple structure, safety and reliability. Background technique [0002] In order to increase the running speed and improve the high-speed running quality, some railway high-speed trains adopt the motor body suspension method, and the torque generated by the motor is direc...
