前言汽车后桥减速器是汽车传动系统中的主要总成之一,而齿轮又是减速器之基本组成部分,因此,进行后桥减速器齿轮的试验从而确定其工作可靠性和耐用性,就具有重要的实际意义。后桥减速器齿轮的试验一般的不外乎道路上的使用试验和室内的试验台试验两种。室内试验时,零件的工作情况虽然和实际使用情况不尽相同,但因其时间短、费用省、条件容易控制、数据比较准确而被广泛利用。本文将着重介绍在试验台上 Rear axle rear axle reducer is one of the main assembly of the car transmission system, and gear is an essential part of the reducer, therefore, after the gear reducer gear test to determine its reliability and durability, on Has important practical significance. Rear axle reducer gear test generally no more than the use of the road test and indoor test bench two. Indoor tests, the parts of the work although the actual use of different conditions, but because of its short time, cost provinces, conditions easy to control, the data is more accurate and widely used. This article will focus on the test bench
