电动绞车刹车装置的设计
摘 要
机械是人类生产和生活的基本工具要素之一,是人类物质文明最重要的一个组成部分。机械工业担负着向国民经济各部门,包括工业、农业和社会生活各个方面提供各种性能先进、使用安全可靠的技术装备的任务,在国家现代化的建设中占有举足轻重的地位。20世纪80年代以来,以微电子、信息、新材料、系统科学为代表的新一代科学技术的发展及其在机械工程领域中广泛渗透、应用和衍生,极大的拓展了机械产品设计制造活动的深度和广度,改变了现代制造业的产品设计方法、产品结构、生产方法、生产工艺和设备以及生产组织模式,产生了一大批新的机械设计制造方法和制造系统。
电动绞车作为一种机械产品,有着理论基础不在局限于力学,制造过程的基础也不只是设计与制造经验及技艺的总结。本设计涉及到了电动机的选取,齿轮与传动装置的设计,还有制动装置的选用以及减速器的计算,最后通过对零件的设计达到最后电动绞车的总装要求。总之,本设计注意到了调整结构,加强科学基础,反映在大学期间学习到的知识的联系和衔接,内容分配合理,即相互联系又避免不必要的重复,在设计中形成自己的特色,对自己以后工作垫下坚实的基础。

Abstract
Machinery is the basic tool of human production and life of human material civilization, is one of the most important part of. Machinery industry is responsible for the national economic sectors, including industrial, agricultural and each aspect of social life with a variety of advanced performance, safe and reliable use of the technology and equipment of the task, in the national modernization construction occupies the position of play a decisive role. Since the nineteen eighties, microelectronics, information, new material, system science as the representative of the new generation of the development of science and technology and in the mechanical engineering field widely, application and derivative, greatly expanding the product design and manufacture of mechanical activity of the depth and breadth of modern manufacturing industry, changed the method of product design, product structure, production methods, production technology and equipment and the production organization pattern, resulting in a large number of new mechanical design manufacturing method and system.
Electric winch is a mechanical product, a theoretical basis is not limited to mechanical, manufacturing process based not only design and manufacturing experience and technology summary. This design involves the selection of electric motor, gear and gear design, and the braking device selection and the speed reducer are calculated, finally through to reach the final parts of the design of electric winch assembly requirements. In short, this design pay attention to adjust a structure, strengthen the scientific basis, reflected in the university period to learn knowledge of contact and connection, content distribution is reasonable, namely the interrelated and avoid unnecessary duplication, in the design of forming its own characteristics, to their later work mat foundation.

1.1 绞车的研究现状
绞车又称为卷扬机,主要运用于建筑、水利工程、林业、矿山、码头等的物料升降或平拖。是用卷筒缠绕钢丝绳或链条以提升或牵引重物的轻小型起重设备。
