自动洗衣机行星减速器设计

摘要

本文完成了自动洗衣机行星减速器的结构设计。该减速器具有较小的传动比，而且，它具有结构紧凑、传动效率高、外廓尺寸小和重量轻、承载能力大、运动平稳、抗冲击和震动的能力较强、噪声低的特点，适用于化工、轻工业以及机器人等领域。这些功用对于现代机械传动的发展有着较重要的意义。

首先简要介绍了课题的背景以及齿轮减速器的研究现状和发展趋势，然后比较了各种传动结构，从而确定了传动的基本类型。论文主体部分是对传动机构主要构件包括太阳轮、行星轮、内齿圈及行星架的设计计算，通过所给的输入功率、传动比、输入转速以及工况系数确定齿轮减速器的大致结构之后，对其进行了整体结构的设计计算和主要零部件的强度校核计算。

Design of planetary reducer for automatic washing machine

ABSTRACT

This completed a single-stage planetary gear reducer design. The gear has a smaller transmission ratio, and it has a compact, high transmission efficiency, outline, small size and light weight, carrying capacity, smooth motion, shock and vibration resistant and low noise characteristics, Used in chemical, light industry and robotics fields. The function of the development of modern mechanical transmission has a more important significance.

First paper introduces the background and the subject of gear reducer situation and development trend, and then compared various transmission structures, which determine the basic type of transmission. Thesis is the main part of the main components of drive mechanism including the sun wheel, planet gear, ring gear and planet carrier in the design calculation, given by the input power, gear ratio, input speed and the condition factor to determine the approximate structure after the gear reducer And to carry out the design and calculation of the overall structure and main components of the strength check calculation.

KEY WORDS: planetary gear，driving machanism，structural design，checking calculation
