从现有几种齿轮加工书籍所提供的滚齿切入长度计算式来看,各种计算式均不一致,计算结果也不相同,有些计算值与实际值相差较大。为能正确计算定额工时和合理设计夹具垫的高度,滚齿时的切入长度应作较正确的理论计算,不能简单沿用原有的一些计算式。现根据滚齿时滚刀刀齿的切削作用过程,推导了斜齿轮滚齿切入长度计算式,供有关技术人员参考,
From the existing gear processing books provided hobbing cut length calculation formula, the various calculations are inconsistent, the calculated results are not the same, some of the calculated value and the actual value of the larger difference. In order to correctly calculate the fixed working hours and the height of the designed jig mat, the cutting length during hobbing should be compared with the correct theoretical calculation, and the original calculation formulas can not be simply used. According to the cutter hobbing tooth hobbing process, the helical gear hobbing incision length calculation formula is derived for the reference of the relevant technical personnel,
