齿轮是机械设备中的重要传动零件,随着机械工业的发展对齿轮精度等参数的要求也越来越严格,对齿轮测量的要求也不断提高,作为一种形状复杂、误差种类比较多的机械零件,齿轮的测量一直是机械测量的难点。国内能对大型齿轮测量的仪器还不多,所以开发一种简单易行的测量方案就十分迫切。 Gear is an important driving part in machinery and equipment. With the development of the machinery industry, the requirements on the parameters such as gear accuracy are becoming more and more stringent, and the requirements for gear measurement are continuously increasing. As a kind of machinery with complicated shapes and many types of errors Parts, gear measurement has always been a mechanical measurement difficulties. Domestic large-scale gear measurement equipment is not enough, so the development of a simple and easy measurement program is very urgent.
