一、盆角齿轮啮合不良的响声盆角齿轮(盆形齿轮和主动齿轮)齿面接触位置不对或齿面啃伤会发出一种不均匀的“哽哽哽”的响声(类似在车床上切削较大的钢件时吃刀量过大而发出的声音),发生这种响声的车速:载货汽车一般在40～50km/h;进口小型汽车多在60km/h。盆角齿轮的异响与其所承受的负荷关系很大,重车爬坡时响声变大,而车辆滑行时一般不响。产生异响的原因有:(1)盆角齿轮齿面接触位置调整不当或齿侧间隙过小,使齿轮有发啃现象。因此在调整盆角齿轮时首先要保证正确的啮合印迹,在此前提下调整齿侧间隙;(2)拆装后桥时改变了盆角齿轮原齿面接触位置。例如有1台伏尔加轿车大修前后桥无异响,拆检时未标记角齿调整垫位置,
First, the poor angle of the gear box gear meshing Badge gear (pot-shaped gear and pinion gear) tooth surface contact position or tooth surface bite will send a non-uniform “哽 哽 哽 ” sound (similar to the lathe On the larger steel cutting large amount of food to eat the amount of the issue of the sound), the speed of this noise: the general cargo truck 40 ~ 50km / h; more small cars imported at 60km / h. The abnormal noise of the corner gear has a great relation with the load that it bears on. When the heavy vehicle climbs, the sound becomes louder, and the vehicle generally does not sound when it slides. Abnormal sound generated due to: (1) angle corner gear tooth surface contact or improper adjustment of the tooth gap is too small, the gear has hair eating phenomenon. Therefore, when adjusting the angle of the corner gear, we must first ensure that the correct meshing imprints, adjust the tooth-side clearance under this premise; (2) When the rear axle is disassembled and changed, the contact position of the original tooth surface of the corner gear is changed. For example, a Volga car overhaul before and after the bridge no abnormal sound, not marked when the demolition tooth angle adjustment pad position,
