你刊85年第1期《提高滚铣100齿以上质数圆柱齿轮的齿向精度》的分析中认为:“选用微齿数z时,其绝对值越小越好。”接着又谈到:“最好选择|z|=1/20～1/50,这是提高齿向精度最好的办法”。究竟如何选择z为好,我的看法如下,供大家参考: (1)从由于差动挂轮未能完全补偿z而引起的齿向误差∑δ_b 计算式来看,见原文式(2),(本文中的代号意义与原文同) ∑δ_b是与括号内的差值成正比的,因此差值越小,∑δ_b越小。而不是z的绝对值越小越好。 (2)现在要求∑δ_b→0,只要因为一般滚齿机中,K_(co)是差动定数为9π、或25、或105/4;
In your analysis of No. 1, Issue 85, “Improving the Tooth Orientation Accuracy of a Hobber with 100 or More Hobs,” the smaller the absolute value is, the better it is. “Then it goes on to say:” Good choice | z | = 1/20 ~ 1/50, which is the best way to improve the gear accuracy. " How to choose z as well, my opinion is as follows, for your reference: (1) from the differential due to the wheel can not fully compensate for z caused by the tooth orientation error δδ_b calculation formula, see the original style (2), (The meaning of the code in this article with the original text) Σδ_b is proportional to the difference between the parentheses, so the smaller the difference, Σδ_b smaller. Rather than the smaller the absolute value of z, the better. (2) It is now required that Σδ_b → 0, as long as the general setting of the hobbing machine is such that K_ (co) has a differential constant of 9π, or 25, or 105/4;
