一前言传统的蜗杆——齿轮减速器设计时,低速级传动比是按总传动的(0.03～0.06)倍数进行估算的,算法比较粗糙,且存在一定的盲目性。用此种方法分配传动比,一般不易得到质量最小的形体结构,有时还可能造成蜗轮与低速轴发生干涉的现象,为此,设计时常需反复试算、修正才能取得较为满意的结果。 A preface The traditional worm - gear reducer design, low-speed transmission ratio is based on the total transmission (0.03 ~ 0.06) multiples of estimates, the algorithm is rough, and there is a certain degree of blindness. In this way, the distribution of transmission ratio is generally not easy to get the least mass of the body structure, and sometimes may cause interference with the worm shaft and the low-speed axis, for which the design often need repeated trial and error to get more satisfactory results.
