圆弧面蜗杆减速器(球面蜗杆减速器),具有结构紧凑、承载能力大、传动效率高、工作寿命长等优点。但加工难度大、装配技术要求高。设计计算、加工装配均得当者,承载能力约比普通蜗轮副提高3～4倍。否则只提高1.4～2.0倍,因生产成本高而得不偿失。去年,我们在生产剎车试验台时,需加工球面蜗杆减速器左、右旋各一套。其蜗杆如图1所示。我们在Y320滚齿机上成功 Circular worm reducer (spherical worm reducer), with a compact, large carrying capacity, transmission efficiency, long working life and so on. But difficult to process, high assembly technology. Design and calculation, processing and assembly are appropriate, carrying capacity of about 3 to 4 times higher than ordinary worm gear. Otherwise only increased 1.4 ~ 2.0 times, because of the high cost of production and outweigh the benefits. Last year, when we produced the brake test rig, we needed to make a set of left and right handed spherical worm reducer. The worm shown in Figure 1. We succeeded in Y320 hobbing machine
