凹面齿(包括圆弧齿)圆柱蜗杆减速器承载能力和效率比较高,工艺比较简单。目前国内外应用广泛。一九八四年我国年产量达到六千台。在我国凹面齿圆柱蜗杆副的齿形与蜗杆精加加安装见图1～图5。五种加工方法所得齿形略有不同,而在性能方面相差甚少。本文参照西德尼曼教授《机械零件》和我们的试验数据,试整理承载能力的计算方法,供大家讨论订正,在设计中试用。 Concave tooth (including arc teeth) cylindrical worm reducer bearing capacity and high efficiency, the process is relatively simple. Currently widely used at home and abroad. In 1984, China’s annual output reached 6,000 units. In China concave cylindrical worm gear tooth profile and the worm plus Canada installed Figure 1 ~ 5. The tooth shapes obtained by the five processing methods are slightly different, with little difference in performance. In this paper, Professor Sidney Niemann “mechanical parts” and our test data, try finishing load capacity calculation method, for discussion, revised, in the design of the trial.
