为了计算2K-H型、3K型行星齿轮传动的速比,可采用一种“十字交叉图解法”,现介绍如下: 1、求2K-H型,单级式,负号机构(转化机构的速比为负值)行星齿轮传动的速比(图1)。已知:Z_1—太阳轮(主动);Z_2—行星齿轮;Z_3—太阳轮(固定);H—转臂 (从动)解:画一方块图(图2),下边为太阳轮的位置,上边为行星轮位置。负号机构则规定为“1+”。使用时对角线交叉相乘,并按静/动的写法,Z_3为
In order to calculate the speed ratio of 2K-H type and 3K type planetary gear transmission, a “cross-over diagram method” can be used, which is described as follows: 1. Seeking 2K-H type, single stage type, Speed ratio is negative) planetary gear ratio (Figure 1). Known: Z_1-sun gear (active) Z_2-planet gear Z_3-sun gear (fixed) H-boom (slave) Solution: Draw a block diagram (Figure 2) with the sun gear on the bottom, Above the planet wheel position. Negative agency is provided for “1 +”. Use diagonal cross multiplication, and according to static / dynamic wording, Z_3 is
