Tooth Surface Deviation Measurement of Spiral Bevel Gear Based on Equidistant Surface Theory

齿面加工误差检测是螺旋锥齿轮制造过程中的关键环节。针对螺旋锥齿轮齿面难以检测的问题,分析了等距曲面理论及其在齿面检测数据处理过程中的应用方法。基于等距曲面理论,确定了齿轮测量中心的理论运动轨迹,获取了实际加工齿面的真实误差,同时,也为一维测头在锥齿轮检测中的推广应用提供了支持。

The tooth surface deviation measurement is a key process in the manufacturing. Aiming at the difficulty in measurement of spiral bevel gear,the equidistant surface theory and its applications to tooth surface measurement and data processing were analyzed. Based on the equidistant surface principle,the theoretical trajectory coordinates of gear measuring center were determined,and the real deviation of the actual tooth surface was obtained. Also,it would provide supports for promoting the application of the one-dimensional probe to bevel gear measurement.
