由于剃齿法有一系列优点,它被广泛应用于齿轮精加工。但剃齿工艺本身,对如何稳定提高齿轮加工精度和剃齿光洁度等还存在着值得研究的问题。本文就如何既能提高剃齿生产效率又能提高剃齿光洁度的问题,进行了探讨。一、影响剃齿光洁度因素的分类从生产实践中可观察到,剃齿时影响齿面光洁度的因素大体上可以分为以下三类: (1)当剃齿刀与工件在一定的径向压力下无间隙紧密啮合时,由于轴向走刀和刀具旋转,在齿面上造成刀刃剃削轨迹,简称“走刀痕迹”。刀痕越粗,光洁度越差;刀痕越细、越密,光洁度越好。但剃齿的刀痕粗细与沿工件轴向走刀量的关系,
Due to a number of advantages of the shaving method, it is widely used in gear finishing. However, shaving process itself, there is still a problem worth studying how to improve the gear machining accuracy and shaving smoothness. In this paper, how to improve the shaving efficiency and improve the quality of shaved teeth is discussed. First, the classification of factors affecting shaving smoothness From the production practice can be observed, shaving tooth surface smoothing factors can be roughly divided into the following three categories: (1) When the shaving cutter and the workpiece in a certain radial pressure Under close-free gap-free engagement, due to the axial and tool rotation, resulting in the tooth surface shaving cutting path, referred to as “walking marks.” The thicker the mark, the worse the finish; the thinner the mark, the more dense, the better the finish. However, the thickness of the tooth shaving and cutting along the workpiece axial relationship between the amount,
