三级圆锥圆柱齿轮减速器设计

摘要

减速机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，减速机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，轮形状可分为圆柱齿轮减速机、圆锥齿轮减速机和圆锥－圆柱齿引轮减速机；按照传动的布置形式又可分为展开式、分流式和同进轴式减速机。减速器是一种由封闭在刚性壳体内的齿轮传动、蜗杆传动、齿轮-蜗杆传动所组成的独立部件，常用作原动件与工作机之间的减速传动装置。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。根据负载情况进行一般的齿轮强度、几何尺寸的设计计算，然后要进行传动比条件、同心条件、装配条件、相邻条件的设计计算。本文的主要研究内容为，齿轮的选型，壳体的空间布局，三级轴的分布，高速轴、低速轴、中速轴的设计及校核，齿轮的选型及校核。

Design of three stage bevel cylindrical gear reducer

ABSTRACT

Reducer between prime mover and work machine or actuator has a function in matching speed and transfer torque reducer is a relatively sophisticated machinery, the use of its purpose is to reduce rotation speed, increase torque, round shape can be divided into cylindrical gear reducer, cone gear speed reducer and cone - cylinder gear wheel reducer; According to the transmission can be divided into the expansion of decorate a form, shunt type and with the shaft speed reducer. Reducer is a kind of the closed in rigid casing of gear transmission, worm drive and gear - worm drive composed of independent components, commonly used for the original reduction drive device between moving parts and working machine. Between the prime mover and work machine or actuator has a function in matching speed and transfer torque is widely applied in modern machinery.According to the load situation general gear strength, the design calculation of geometry size, and then to transmission ratio condition, concentric condition, assembly condition, design and calculation of the adjacent conditions.In this paper, the main research contents of the, gear selection, shell of space layout, distribution of three axis, high-speed shaft, low speed shaft, intermediate shaft design and checking, gear selection and checking.
