减速器在制造过程中，由于箱体加工误差，齿轮加工误差，热处理变形以及装配综合误差等，在有些情况下造成齿面接触率偏低，降低了减速器的使用寿命。为了消除各类误差，提高齿面接触率，改善齿面粗糙度，除在加工方面采取一定措施外，在装配方面可采取研齿的方法。1．研齿前的 Reducer in the manufacturing process, due to the box processing error, gear machining error, heat treatment deformation and assembly of the integrated error, in some cases caused by low contact rate of the tooth surface, reducing the service life of reducer. In order to eliminate all kinds of errors, improve the contact rate of the tooth surface and improve the tooth surface roughness, in addition to take some measures in the processing, the assembly can take the method of grinding teeth. 1. Before grinding teeth
