现行的苏联双圆弧齿轮标准中,还没有不等移距变位传动方面的内容。本文提供一种简易可行的双圆弧齿轮不等移距变位几何尺寸的计算方法。计算的关键是如何确定变位系数。设两圆弧齿轮变位时分度圆分离大小为Δa_w,则Δa_w=x_∑m,其中 x_∑为两齿轮变位系数之和(即 x_∑=x_1+x_2),m 为法面模数。首先根据工作条件和传动的用途选定压力角。对于一般减速器来说,α的许用范围为9°～12°。
The current Soviet double-arc gear standard, there is no range of variable displacement transmission aspects. This article provides a simple and feasible method of calculating the geometrical dimensions of double-circular arc gear ranging from displacement to displacement. The key to the calculation is how to determine the coefficient of variation. When two arc gears are displaced, the size of the separation circle is Δa_w, then Δa_w = x_Σm, where x_Σ is the sum of the displacement coefficients of the two gears (ie x_Σ = x_1 + x_2), and m is the plane modulus. First, select the pressure angle according to the working conditions and the purpose of the transmission. For a typical reducer, the allowable range of α is 9 ° ~ 12 °.
