在Y37和Y38滚齿机上加工斜齿轮或大质数齿轮时,需要计算挂轮。这个工作即使是利用对数挂轮表,仍然非常繁琐。我们从《齿轮工手册》“比值挂轮表使用说明”中,受到启发,摸索了一套利用袖珍电子计算器计算挂轮的方法,不需要任何挂轮表,也能方便地算出挂轮表。它的原理:如果有一个真分数U/V与给定的小数N,只有很小的误差ε,即U/V-N=ε,将该式移项得:V-N=U-Vε; 这个式子表明对给定小数N(挂轮速比)乘以整数倍V之后,可以得
When machining helical gears or large prime gears on Y37 and Y38 gear hobbing machines, it is necessary to calculate the sprocket. This work is even more tedious even with the logarithmic wheel table. We from the “Gear Manual” “linked to watch the use of instructions,” inspired by, explored a set of pocket calculator using pocket calculator method, do not need any hanging round table, but also can easily calculate the hanging round table . Its principle: If there is a true fraction U / V with a given fraction N, only a small error ε, that is, U / VN = ε, the formula is: VN = U-Vε; This formula shows For a given decimal N (wheel speed ratio) multiplied by an integer multiple V, can be obtained
