Bridge crane is necessary to handling large or heavy equipment parts inside the workshop in our life.That is control of the car to move forward and reverse on the bridge girder. Bridge type hoist crane Car movement organization mounted on the small frame with the lifting organization. And it is consisted of reducer, motor, brake, the driving wheel group, the driven wheel group, the transmission shaft and so on. In this paper, the bridge crane is designed for using indoor, and it would be located in the workshop equipped with the need to carry the heavy parts frequently, because of that the natural condition has an relatively small influence on its work. 5T type bridge crane is belong to the small and medium-sized equipment in the industry, crane load is not so high, that the range of the selection of parts is relatively wide in this design.Keywords：Car Movement Organization; Bridge Type Hoist; Small Frame; Reducer目 录摘 要IAbstractII第一章 引 言11.1 起重机的定义11.2 起重机的工作原理11.2.1 驱动装置11.2.2机构组成21.2.3 起升取物装置21.3 国内外起重机发展状况2第二章 桥式起重机的介绍32.1组成和特点32.2 桥式起重机的分类32.2.1 通用桥式起重机32.2.2 专用桥式起重机32.2.3 电动葫芦型桥式起重机42.3小车42.3.1 起升机构52.3.2 小车架52.3.3小车运行机构52.3.4 安全装置62.4 本次毕业设计中的内容72.4.1主要参数72.4.2结构特点8第三章 小车运行机构及小车架93.1小车运行机构设计分析93.2确定传动方案93.3 桥式起重机小车架
