摘要

减速器是一种由封闭在刚性壳体内的齿轮传动、蜗杆传动或齿轮—蜗杆传动所组成的独立部件，常用在动力机与工作机之间作为减速的传动装置；在少数场合下也用作增速的传动装置，这时就称为增速器。减速器由于结构紧凑、效率较高、传递运动准确可靠、使用维护简单，并可成批生产，故在现代机措中应用很广。

我所设计的慢动卷扬机传动装置，是以减数器为主体，外加电动机和滚筒，实现以规定得速度推动物体的功能。性能可靠，结构简单，紧凑，便于制造。

其主要设计思路来自于对推力机工作原理的分解,然后按照相应功能的机

构部件进行设计,对比,选定,以及优化组合。综合利用电动机、推头、丝杠、减速器等部件的协调运动,来实现推力机得预设功能。所有部件的设计都经过科学得数据处理并利用Auto Cad软件强大绘图功能和Word的编辑功能,使设计方案图文并茂,栩栩如生.

Abstract

Reducer is an enclosed by a rigid casing of gear transmission, worm transmission or gear - worm transmission, which is composed of independent components used in the study and work as a deceleration machine, between the transmission device, In a few cases are used to speed transmission device, this is called the growth. Due to the structure is compact, gear reducer, high efficiency and reliable motion using simple maintenance and batch production in the modern machines, so it is widely used in the measures.

I designed by slow-moving hoist device is termed as main body, and motor and roller, to realize the provisions of the object function. Speed drive Reliable in performance, simple in structure, compact, easy to manufacture.

The main design ideas from the working principle of thrust machine, then according to the corresponding functional components design, organization, and the optimal portfolio selection. Comprehensive utilization of the motor and reducer, ball screw, pusher and to realize the coordinated movement, the default function to thrust machine. All components design through scientific data processing and using Auto Cad software powerful drawing function and Word of editing functions, which makes the design scheme illustrated, lifelike.
