1、NGW型传动的配齿方法及齿数组合表对于一般动力传动用行星传动，不要求十分精确的传动比，在已知要求的传动比的情况下，可按以下步骤选配齿数①根据，按表行星轮数目与传动比范围中表选取行星轮数目Cs，通常选Cs＝3~4②根据齿轮强度及传动平稳性等要求确定太阳轮齿数zA③根据下列条件试凑Y值：(a)Y＝zA——传动比条件；(b)Y/Cs＝整数——装配条件；(c)Y应为偶数——同心条件。但当采用不等啮合角的角变位传动时，Y值也可以是奇数④计算内齿圈及行星轮齿数zB和zCzB＝Y-zA对非角变位传动对角变位齿轮传动式中，ΔzC为行星轮齿数减少

2、值，由角变位要求确定，可为整数，也可以为非整数，ΔzC＝0.5~2下表为NGW型行星齿轮传动的常用传动比，常用行星轮数对应的齿轮齿数组合表NGW型行星齿轮传动的齿数组合i＝2.8Cs＝3Cs＝4Cs＝5zAzCzBzAzCzBzAzCzB3213582.81253313592.78793213582.81254116732.78053715672.81083916712.82054317772.79074317772.79074317772.79074719852.80854619852.80854519842.82614920
