在磨齿机工作中,齿形误差是比较复杂的,因为它的表现形式较其他误差更为多■同时,齿形精度又是影响齿轮传动平稳性■少齿轮噪声的一项重要质量指标。因此,■齿形误差的产生原因及其消除方法是修理和日常维护调整中经常碰到的问题。下面以 Y7131磨齿机磨齿齿形为例,说明齿形误差产生原因及其消除方法。一、磨削齿形误差的形成Y7131磨齿机是目前工厂最常用的一种齿轮精加工机床,它是按照齿轮与齿条啮合的原理进行磨削的。锥面砂轮代表“假想齿条”的一个齿,被磨齿轮是以磨削节圆(其直径为d_k)沿着“假想齿条”的节线作纯滚动,这就是磨
In the working of a gear grinding machine, the tooth profile error is more complicated because it has more manifestations than other errors. ■ At the same time, the profile accuracy is one of the important quality indicators that affects the gear stability. Therefore, ■ Causes of tooth-shaped errors and their elimination are problems often encountered in repairs and routine maintenance adjustments. The following to Y7131 gear grinding machine tooth as an example, indicating the cause of tooth-shaped error and its elimination method. First, the formation of grinding tooth error Y7131 gear grinding machine is currently the most commonly used plant a gear finishing machine, which is based on the principle of gear and rack meshing grinding. Conical grinding wheel represents a “hypothetical rack” a tooth, the grinding gear is grinding pitch circle (its diameter d_k) along the “imaginary rack” pitch line pure rolling, which is the mill
