摘要 本论文主要阐述的是一套系统的关于单级蜗轮蜗杆减速器的设计方法，单级 蜗轮蜗杆减速器是蜗轮蜗杆减速器的一种形式。蜗轮蜗杆减速器的特点是具有反 向自锁功能，可以有较大的减速化，输入轴和输出轴不在同一轴线上，也不在同 一平面上。但是一般体积较大，传动效率不高，精度不高。由于在传动的理论上, 工艺水平和材料品质方而没冇突破，因此没能从根本上解决传递功率大，传动比 人，体枳小，重量轻，机械效率高等这些基木耍求。 在论文中，首先阐述了论文的设计要求，蜗轮蜗杆减速器的特点以及发展现 状；接着阐述了蜗轮蜗杆减速器的设计原理和理论计算。然后按照设计准则和设 计理论设计了单级蜗轮蜗杆减速器。接着对减速器的部件组成进行了尺寸计算和 校核。该设计代表了单级蜗轮蜗杆减速器的一般设计过程，对于其他的蜗轮蜗杆 的设计工作也冇一定的价值。 关键词：减速器蜗轮蜗杆反向自锁 Abstract This paper describes the design of a single-stage worm gear units on a set of systems,single-stage worm gear reducer is a form of worm reducer. Worm gear units are characterized by a reverse self^locking feature, you can have a greater reduction of the input shaft and output shaft are not on the same axis, not in the same plane. But generally larger, the transmission efficiency is not high, accuracy is not high. In the paper, the paper first describes the design requirements worm gear characteristics and development status; then describes the design principle of worm reducer and theoretical calculations. Then follow the design criteria and design theory designed single-stage worm gear units. Then the gear unit size of components were calculated and checked? The design represents the general design of single-stage worm reducer worm for other design work also has a certain value. Mostly domestic reducer gears, worm drive based, but the prevalence of small power to weight ratio, or gearing ratio and low mechanical efficiency issues. Also on the material quality and technological level, there are many weaknesses. Since there is no breakthrough in theory, technological level and quality of the material aspects of transmission, so there is no fundamental solution to transfer power, transmission ratio, small size, light weight, the mechanical efficiency of these basic requirements. Keywords: reduction gear; worm gear; reverse self-locking 第1章绪 TOC \o 1-5 \h \z HYPERLINK \l bookmark6 \o Current Document 1.1设计背景及意义 1 1.1.1设计要求 1 1.1.2蜗轮蜗杆减速器的优点 1 HYPERLINK \l bookmark8 \o Current Document 1.2
