Abstract

The invention provides a method and system for detecting the quality of the main and driven gears in the main reducer of the rear axle of an automobile. The method includes: determining the driving gear and the driven gear to be detected; Dye; Assemble the dye-coated driving gear and the driven gear to the final reducer, and control the rotation of the dye-coated driving gear and the driven gear, during the rotation, the dye-coated driving gear and the driven gear mesh with each other to cause the dye Deformation occurs to form imprints, which characterize the meshing contact surface of the main and passive gears; take pictures of the meshing contact surfaces of the main and passive gears to obtain the meshing contact surfaces of the main and passive gears, and compare the meshing contact surfaces of the main and passive gears with the pre-stored standard template Yes; when the meshing contact surface of the main driven gear is consistent with the standard template, it is determined that the quality of the driving gear and the driven gear is qualified. The invention ensures that the quality of the main gear is qualified and improves the NVH performance of the rear axle of the automobile.

Description

technical field [0001] The invention relates to the technical field of automobile parameter detection, and more specifically, relates to a method and system for detecting the quality of the main and driven gears in the final drive of the rear axle of the automobile. Background technique [0002] The NVH (Noise Vibration and Harshness, noise, vibration and harshness) test results of the car show that the car rear drive axle (hereinafter referred to as the car rear axle) is an important part of the car transmission system, and the NVH performance of the car rear axle is in the car It has a huge impact on vehicle noise and ride comfort when driving. Among them, the order noise generated by the meshing of the main gear (driving gear and passive gear) of the main reducer of the rear axle of the automobile is the most important noise source of the rear axle of the automobile. Generally, the higher the order noise of the final drive, the greater the overall noise and vibration of ...
