一、概述在汽车行业中,成批和大量生产精度较高的齿轮,对铣出或插出的未淬硬齿轮采用剃齿工艺进行加工,能使齿轮的齿距、截形、分圆偏心和齿的形状得到较高的精度。剃齿后的齿轮精度能达到新标准5～6级,加工表面光洁度能达到7～9级。在剃齿过程中,因剃齿刀和齿轮的啮合,截形上每点产生相对滑移,这种相对滑移速度,就是剃齿时起括削作用的切削速度。由于剃齿刀齿侧面有许多小槽,槽与齿面的交线就是切削刃,被加工齿轮沿着它
First, an overview In the automotive industry, mass and mass production of high precision gear, the milling or unplugged gear hardened gear processing, gear pitch, truncation, eccentricity And tooth shape get higher accuracy. After gear shaving gear accuracy can reach the new standard of 5 to 6, the processing surface finish can reach 7 to 9. In the shaving process, due to the engagement of the shaving cutter and the gear, the relative slip occurs at each point of the truncation. This relative slip speed is the cutting speed of the shaving cutter. As the tooth shaving side of the face there are many small grooves, groove and tooth surface intersection is the cutting edge, the gear is processed along it
