Gear box test bench

Abstract

The invention provides a gear box test bench, relates to the field of rail transit, and the test bench is used for testing a to-be-tested mechanism, and the to-be-tested mechanism comprises a gear boxwhich comprises an input end and an output end; a shaft component which is arranged at the input end or the output end. The gear box test bench includes a support mechanism supported at both ends ofthe shaft member, at least one of the both ends of the shaft member being supported by the support mechanism so as to be supported on an end surface of the at least one of the both ends. According tothe gear box test bench provided by the invention, at least one of the two ends of the shaft component is supported by the supporting mechanism in a manner of being supported on the end surface of theat least one, so that compared with a bearing support in the prior art, the supporting manner has higher mounting and dismounting speed, higher test efficiency. Due to the fact that the gear box testbench is supported on the end face of the shaft component, the shaft component cannot be scratched in the mounting and dismounting process, and the quality of the to-be-tested mechanism is ensured.

Description

technical field [0001] The application relates to the field of rail transit, in particular to a gearbox test stand. Background technique [0002] In order to ensure product quality, gearboxes such as rail transit gearboxes need to undergo routine tests before leaving the factory. The existing rail transit gearboxes are usually assembled with the axles before leaving the factory. For this kind of products, such as image 3 As shown, the existing test bench usually uses double bearing supports to support the axle, and the drive motor is connected to the input shaft through the flange to carry out tests at various speeds. For the cooperation between the bearing and the axle, please refer to Figure 4 . [0003] Therefore, the existing test bench needs to install the bearing to the test gearbox axle before the test, and remove it after the test. This results in the assembly and disassembly of the bearings taking a certain amount of time, and can easily cause scratches on the a...

AI Technical Summary

Problems solved by technology

This leads to the assembly and disassembly of bearings taking a certain amount of time, and if the operation is not done properly, it is easy to cause scratches on the axle

In addition, the aforementioned test bench needs to connect the motor to the input of the test gearbox for each test, and only one product can be tested at a time, which also leads to low test efficiency
