摘要
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作用的就是减速机，它相对来说比较精密。使用的目的是降低机器的转速，增加机器的转矩。它是一种由封闭在刚性壳体内的齿轮传动、齿轮-蜗杆传动所组成的独立部件，常常用在原动件与工作机之间的减速装置 。在原动机和工作机之间担任着不可小觑的作用，在机械中有极为广泛的应用。它是工业诸多领域的机械传动装置，行业涉及的产品类别包括了各类齿轮减速机、行星齿轮减速机及蜗杆减速机，也包括了各种专用装置，如增加速度的装置、调节速度的装置、还有包括柔性传动装置在内的各类传动装置等。按照级数可分为单级和多级减速机；按照形状可分为圆柱齿减速机、圆锥齿减速机和圆锥－圆柱齿引轮减速机；按照分布形式又可分为展开式、分流式和同进轴式减速机。
我们国家的减速机行业发展历史已接近40年，无论是在那种工业中，减速机产品都有着广泛的应用。各类行业都对它有及其大的诱惑。因为极大的市场需求才催生了激烈的行业竞争。在残酷的市场竞争中，减速机行业必须加快淘汰已经落后的产能，大力发展高效节能的产品，充分利用国家节能型产品惠民工程政策机遇，产品更新的力度要加大，产品结构要调整，也要关注国家产业政策，用以应对复杂多变的经济环境，让行业保持良好的发展势头。本设计设计的是三级圆柱齿轮减速器，并对其进行应力分析。

Abstract
Including many, often by a torque of reducer is in the original motivation and working machine or execution mechanism between matching speed and torque transfer function, it is relatively more sophisticated. To reduce the machine speed, increase the machine. It is enclosed in a rigid shell body of the gear transmission, gear - worm transmission, which is composed of independent components used in the motivity and work machine deceleration device. In the original motivation and working machine as a force to be reckoned with in machinery has a very extensive application. It is an industrial area of mechanical transmission device, the industry involved in the products of all kinds of gear reducer, planetary gear reducer and cochlear Rod reducer, including the various special equipment, such as increase the speed of the device and speed regulating device, including flexible transmission device, including all kinds of transmission device. According to the series can be divided into single stage and multi-stage reducers; divided according to the shape of cylindrical gear, circular bevel gear reducer and cone cylindrical gear lead wheel reducer; according to the distribution form and can be divided into type, shunt type and the same shaft type speed reducer.
Our country's reducer industry development history is close to 40 years, both in that industry, reducer products are widely applied. Industry of of all kinds are to have and the temptation. Because of the great market demand it gave birth to the fierce competition in the industry. In the fierce market competition, the reducer industry must accelerate the elimination of backwardness has production capacity, vigorously develop energy-efficient products, make full use of the national energy-saving products Huimin project policy opportunities, by the strength of product updates to increase, product structure to adjust, but also should pay attention to the national industrial policy, to deal with the complicated and changeable economic environment that will allow the industry to maintain the good momentum of development. Design and design of the three cylindrical gear reducer, and its stress analysis.

传动装置总体设计
展开式硬齿面圆柱齿轮减速器 如图2.1主有两大系列，平行轴系列和垂直轴系列。平行轴减速器是按国家标准(GBl9004—88)生产，它主要包括ZDY(单级)、ZLY(两级)、ZSY(三级)和ZFY(四级)四大系列，垂直轴减速器是按国家标准(JB/T9002—1999)生产，主要在输入轴与输出轴呈垂直方向布置，它主要包括DBY、DCY和DFY三大系列。此次设计的是三级展开式硬齿面圆柱齿轮减速器（ZYS280-25-108）。
减速器的特点是：（1）齿轮传动圆周速度不大于20米/秒；（2）工作环境40～50℃，如果低于0℃，启动前润滑油应预热至0℃以上。同时，用绘图软件进行绘制二维装配图、轴的的零件图等等。接下来在用SW对单个零件进行建模和装配三级减速器的同时仿真出视频；最后，对三级减速器进行有限元分析，进行结构方面的优化改善和创新。
