精度较高的齿轮,一般都须进行热处理。热处理后欲使齿输保持较高精度,采用珩磨较磨齿或研齿法有很多优点。由于珩磨轮的切削速度比研齿时的滑动速度高得多,齿面可获得很高光洁度,生产效率亦高。又由于渐开线啮合时的相对滑动与珩磨轮传递给齿轮的切削压力交变的结果,珩磨后齿顶处 High precision gear, generally have to be heat treatment. After heat treatment to make the teeth lose high accuracy, the use of honing grinding or grinding method has many advantages. Due to the honing wheel cutting speed than the tooth when the sliding speed is much higher, tooth surface can get very high finish, the production efficiency is also high. As a result of the relative sliding of involute engagement and the cutting pressure transmitted to the gear by the honing wheels,
