Research On Auto Main Reducing Gearbox Tester

Main reducing gearbox is a key part of the auto driving axle and the auto driving system. Its main function is to increase the input torque and decrease the speed of rotation, and its assembly precision will directly influence or decide the precision of the driving axle. Quality of main reducing gearbox influences automobile quality. And auto testing is the important method to ensure auto performance, improve auto mass and enhance competition. The paper will research structure and technology of main reducing gearbox tester.Firstly, the paper introduces the actuality of auto industry and the system of auto. Then the paper researches structure of main reducing gearbox and standard of main reducing gearbox testing technology. The tester test no-load resistance moment, rotational speed and power, differential behavior of main reducing gearbox to judge quality of main reducing gearbox. The tester is capable of testing six breed main reducing gearbox. The paper introduce main reducing gearbox tester from machine part, air-powered part, control part.The control part of system is based on machine part to make system automatic tester. So structure of the machine part should be in reason and be accord of capability. The machine part includes clamp part and transmission part. The clamp part is the place of fixing work piece. So intensity of the clamp part must meet requested intensity of testing. The paper analyses intensity of the clamp part by Finite Element Method.
