二级圆柱齿轮减速器速比分配规律探讨

Speed Rate Distribution Rule of Two stepCylinder Speed reducer Gear

以便于润滑、等接触疲劳强度为前提，推导出二级圆柱齿轮速比分配方程。利用计算机作出高速级传动比随总传动比的变化关系，采用最小二乘法，拟合出传动比分配的简便公式。

Under the conditions of easy lubrication and similar fatigue strength,a formula which is used to distribute the speed rate of two step cylinder reducer gear is derived.The relation between high step speed rate change with the change of low step speed rate has been canculated,and a simple formula of speed rate distribution has been fitted out with least square principle.
