6级精度(JB179—83)以上硬齿面齿轮的精加工,目前常采用磨齿方法。磨齿又分为展成和成型磨齿两大类。成型磨齿效率高,并同样可达到高精度。成型磨齿法需要很好解决砂轮修整问题,为此我们制造了一种新的高效渐开线砂轮修整器。修整器结构及磨齿原理逼近渐开线磨齿法的基本原理,是用较小直径的基圆代替齿轮原来的理论直径基圆,将代用基圆所产生
6-level precision (JB179-83) above the hardened gear finishing, grinding methods are often used now. Grinding teeth is divided into the development and forming two types of grinding teeth. Forming grinding teeth high efficiency, and can achieve the same high precision. Forming grinding method needs to be very good to solve the wheel dressing problem, for which we have created a new high efficiency involute grinding wheel dresser. The basic principle of the dresser structure and grinding gear approaching the involute grinding method is to use the smaller diameter base circle instead of the original theoretical base diameter of the gear to generate the base circle
