我们在民品生产中,经常遇到短齿渐开线齿轮加工问题。由于批量小,专门定制滚刀不经济。我们利用旧标准滚刀进行修磨,解决了这种齿轮的加工。大家知道,用齿轮滚刀滚切轮齿时,被切齿轮的齿根高及径向间隙是由滚刀齿顶高保证的,故我们可以根据被切齿轮的实际齿根高和径向间隙来修磨齿轮滚刀。计算步骤如下: 1按图纸要求,计算所加工齿轮的齿根高即h_f=(d-d_f)/2 式中h_f——齿根高 d——分度圆直径 d_f——齿根圆直径
In the production of civilian products, we often encounter short tooth involute gear processing problems. Due to the small batch, specially customized hob uneconomical. We use the old standard hob grinding to solve this gear processing. As we all know, with the gear hobbing cut gear, the cut gear tooth root height and radial clearance is guaranteed by the hob tooth top, so we can cut the gear according to the actual root height and radial clearance Sharpen gear hobs. Calculation steps are as follows: 1 according to the drawing requirements, calculate the gear tooth root height that is h_f = (d-d_f) / 2 Where h_f - tooth root height d - diameter of the dividing circle d_f - root circle diameter
