在技改过程中,为了降低车床主轴的转速,,我们试制了一齿差皮带轮减速器,代替原皮带轮,经运转性能良好,传动比大、结构简单紧凑、体积小、制造容易。结构原理如图所示。在皮带轮2的支撑壁圆周上镗三个等分孔,装上三套行星齿轮3、13。当电机(n=1400转/分)经皮带传动使皮带轮2转动时(i=2:1, h_2=700转/分),行星轮轴4和皮带轮2同速转动,行星齿轮3(Z_3=20)和13(Z_13=19)分别绕固定太阳轮6(Z_e=60,m
In the process of technological innovation, in order to reduce the speed of the lathe spindle, we tried a tooth-difference pulley reducer, instead of the original pulley, good running performance, large transmission ratio, simple structure, small size, easy to manufacture. Structure principle as shown. On the circumference of the support wall of the pulley 2 boring three equal holes, fitted with three planetary gears 3,13. The planetary shaft 4 and the pulley 2 rotate at the same speed when the motor (n = 1400 rpm) is driven by the belt to rotate the pulley 2 (i = 2: 1, h_2 = 700 rpm) and the planetary gear 3 ) And 13 (Z_13 = 19) around the fixed sun gear 6 (Z_e = 60, m
