一、概述摆线齿轮常用于摆线针轮液压马达和摆线针轮减速器中,在这种机构中,摆线齿轮(转子)的制造精度不高,将严重地影响其运动平稳性、效率和寿命,因此,这种机构对摆线齿轮的制造精度要求很高,对其齿廓形状的检测就成为关键。由于摆线齿轮的齿廓形状为短幅外摆线的等距线,目前国内生产中仅检测其公法线长度是不够的,因为用这种方法实际上只检测了齿廓上两个特定点间的距离,而没有实现对齿廓形状的检测。虽然摆线齿轮的齿廓形状还可用 First, an overview Cycloidal gear is commonly used in cycloid gear motor and cycloid reducer, in which institutions, cycloid gear (rotor) manufacturing accuracy is not high, will seriously affect the smoothness of its movement, Efficiency and life expectancy, so the mechanism of cycloid gear manufacturing precision is very high, the detection of its profile shape has become the key. Due to the cycloidal gear tooth contour shape is short equatorial equatorial line, the current domestic production of only the detection of its normal length is not enough, because this method is actually used to detect only two specific tooth profile Between the distance, but did not achieve the detection of tooth profile shape. Although the cycloidal gear tooth profile shape is also available
