目前,成型磨齿工艺在国内的高精度淬硬齿轮生产中应用甚少,究其原因主要关键是成型砂轮的修整。以住采用靠模修整,由于靠模制造难度大,精度差,成本高,调整时间长,所以只适用于成批生产。其实,成型磨齿具有展成磨齿所不及的优点,如能解决成型砂轮的修整技术,它就为广大工厂所采用。为此,今就两类磨齿工艺作一介绍。一、磨齿方法和分类根据齿轮渐开线的形成,磨齿
At present, the molding grinding tooth technology in the domestic production of high-precision hardened gear rarely used, the main reason is the formation of grinding wheel dressing. To live by the use of mold trimming, due to mold manufacturing difficult, poor accuracy, high cost, long adjustment time, it is only suitable for mass production. In fact, the formation of grinding teeth with less than the benefits of the development of grinding, as can solve the molding wheel dressing technology, it is used by the majority of factories. To this end, two types of grinding gear made an introduction. First, grinding methods and classification According to the involute gear formation, grinding teeth
