在机床传动和汽车后桥差速系统中,以及其他机械制造中,直齿圆锥齿轮,由于能传递相交轴之间的扭矩而获得了广泛的应用。随着社会主义建设事业的飞跃发展,锥齿磨削、精密锻造,粉末冶金等新工艺新技术的大量采用,对直齿圆锥齿轮的精度和互换性都提出了更高的要求。但是,由于目前锥齿轮的测试设备较少,难于满足生产上的需要,因此,我们对直齿圆锥齿轮齿向误差的测试方法进行了探索。直齿圆锥齿轮的齿向误差,是评定直齿圆锥齿轮接触精度的重要单项指标之一。在生产过程中,能否正确测量和控制齿向误差,对于提高产品质量具有十分重要的意义。下面将介绍一种直齿圆锥齿 Spur bevel gears are widely used due to their ability to transmit torque between intersecting axes in machine tool drives and rear axle differential systems, as well as in other machine building applications. With the rapid development of socialist construction, the adoption of new technologies such as bevel gear grinding, precision forging, and powder metallurgy has brought a higher demand on the accuracy and interchangeability of spur bevel gears. However, due to the current bevel gear test equipment is less difficult to meet production needs, therefore, we test the tooth straightness of the bevel gear tooth error test. Tooth gear bevel gear error, is to assess the accuracy of straight bevel gear contact an important single indicator. In the production process, the ability to correctly measure and control the tooth error, for improving product quality is of great significance. Here’s a straight bevel tooth
