1、 I 摘 要 减速器在原动机和工作机或执行机构之间起匹配转速和传递转矩的作用， 在现代 机械中应用极为广泛。减速器按用途可分为通用减速器和专用减速器两大类，两者的 设计、制造和使用特点各不相同。 上世纪 7080 年代，世界上减速器技术有了很大的发展，且与新技术革命的发 展紧密结合减速器是原动机和工作机之间的独立的闭式传动装置， 用来降低转速和增 大转矩，以满足工作需要，在某些场合也用来增速，称为增速器。减速器是一种相对 精密的机械，使用它的目的是降低转速，增加转矩。其主要由传动零件(齿轮或蜗杆)、 轴、轴承、箱体及其附件所组成。减速器按用途可分为通用减速器和专用减速器两大 类，两者的设计、制
2、造和使用特点各不相同。当今世界减速器正被越来越多地应用各 种民用和军用设备上，另一方面，人们对减速器的要求随着时代的变革也在发生着变 化，体积小、重量轻、噪声低、效率高、可靠性高的减速器更受人们喜爱，减速器也 正朝着高水平、高性能的方向不断推进。 关键字：关键字：减速器 转矩 传动零件 轴承 II Abstract Speed reducer in the original motivation and implement mechanism between the matching speed and torque transfer function, in the modern machi
