最近佳纸集团轻机公司接受了带岭造纸厂委托加工m_n=1.75mm斜齿轮的任务。我们没有m_n=1.75mm的滚刀,借刀不好借,买刀既费时又无资金,即便买回来利用率也不高。考虑到能否更改一下原设计,即把模数增大一点,齿数减少一些,保持速比、中心距不变的更改设计。实践证明,方法可行,效果良好(带岭造纸厂反映)。现介绍如下: Recently, Jiaogu Paper Light Company accepted the task entrusted by Lingling Paper Mill to process m_n = 1.75mm helical gears. We do not have m_n = 1.75mm hob, borrow bad borrow, buy a knife is both time-consuming and unfunded, even if the buy-back utilization is not high. Taking into account the ability to change the original design, that is, to increase the modulus a little, to reduce the number of teeth, to maintain the speed ratio, the center distance of the same change design. Practice has proved that the method is feasible, the effect is good (with Ridge paper mill). Now introduced as follows:
