提高齿轮精度、减少齿轮噪声可采用磨齿、剃齿或珩齿几种方法。但是磨齿生产效率低,成本高,不适于大量生产;珩齿可提高齿面光洁度,但对提高齿形精度的作用较小,只有剃齿才是提高齿形精度的高效生产方法。齿轮的剃齿过去是在齿轮表面强化前进行,然而表面强化后(渗碳、碳氮共渗、高频)齿形往往会产生较大的变化而影响齿形精度,齿轮的噪声也较大,但把剃齿放在表面强化后进行却面临困难。
Improve gear accuracy, reduce gear noise can be used grinding, shaving or honing several ways. However, the grinding efficiency is low and the cost is high, which is not suitable for mass production. Honing can improve the tooth surface finish, but it has less effect on improving the tooth profile precision. Only the shaving is the efficient method to improve the tooth profile accuracy. Gear shaving used to be done before the gear surface was strengthened, however, the surface shape of the gear (carburizing, carbonitriding, high frequency) tooth shape tend to have a greater change and affect the tooth profile accuracy, the gear noise is also larger , But the shaving on the surface after strengthening it is facing difficulties.
