根据实践调查和有关资料表明,齿轮变速箱的寿命主要取决于转换齿轮的寿命,而齿端磨损是转换齿轮失效的主要原因。本文仅就如何减小齿端磨损量提出两种途径,一是改变齿端几何形状,二是提高氰化层的含氮量,从而利用齿端几何形状的吻合性和提高材质的耐磨性,来求得转换齿轮端部磨损量的减小。 According to the practical investigation and the relevant data, it shows that the life of the gearbox depends mainly on the life of the changeover gear, while the wear on the tooth end is the main reason for the failure of the changeover gear. This article only on how to reduce the tooth end wear put forward two ways, one is to change the tooth end geometry, the second is to raise the nitrogen content of the cyanide layer, so as to take advantage of the tooth end geometry fit and improve the material wear resistance , To find the conversion gear end wear reduction.
