在橡胶生产和塑料生产中,带有不等螺距的蜗杆的机器得到了广泛的使用。这种蜗杆在普通车床上很难切出。本文介绍苏联车工革新者M·C·卡查罗契夫在1A62车床上加工不等螺距蜗杆的装置,它利用两个相同的切有梯形螺纹的锥形轮1和2,用三角皮带3连接,来代替变换齿轮的托架。锥形轮1和2分别用键装在变速箱和走刀箱的轴上,用轴4和压紧垫圈5固定。在两轴颈处套有青铜轴套6;用压板7和螺帽8把两轴颈固定起来,并保持一定的
In rubber and plastic production, machines with worm gears of unequal pitch are widely used. This kind of worm is difficult to cut out on the ordinary lathe. This article describes the mechanics of the Soviet carmaker MC Chacharov in the 1A62 lathe machining unequal pitch worm gear, which uses the same cut with tapered thread conical wheels 1 and 2, connected with a V-belt 3 , Instead of changing gear bracket. Conical wheels 1 and 2 are keyed to the shaft of the gearbox and the toolbox, respectively, with shaft 4 and compression washer 5 fixed. In the two journals with bronze sleeve 6; with plate 7 and nut 8 to the two journals fixed, and maintain a certain
