内容简介：

河南理工大学万方科技学院本科毕业论文 摘 要 本次毕业设计是针对毕业实习中桥式起重机所做的具体到吨位级别的设计。我国现在应用的各大起重机还是仿造国外落后技术制造出来的，而且已经在工厂内应用了多年，有些甚至还是七八十年代的产品，无论在质量上还是在功能上都满足不了日益增长的工业需求。如何设计使其成本最低化，布置合理化，功能现代化是我们研究的课题。本次设计就是对小吨位的桥式起重机进行设计，主要设计内容是 10t 桥式起重机的结构及运行机构，其中包括桥架结构的布置计算及校核，主梁结构的计算及校核，端梁结构的计算及 校核，主端 梁连接以及大车运行机构零部件的选择及校核包括 : 轮压计算及强度验算 , 运行阻力计算 ,选择电动机 ,减速器的选择验算 ,运行速度及实际功率 ,选择制动器 ,选择联轴器 ,低速浮动轴的验算 ,缓冲器的选择 等计算。还有小车的运行和起升机构零部件的选择及校核包括 : 运行阻力计算 ， 选电动机 ， 选择减速器 验算起动时间 ， 按起动工况校核减速器功率 ， 选择制动器 ， 选择高速轴联轴器及制动轮 ， 验算低速浮动轴强度 ， 钢丝绳的选择 ， 滑轮、卷筒的计算 ，联轴器的选择 。 关键词 : 起重机 ； 大车运行机构 ；小车运行结构；小车起升结构； 桥架 ；主端梁 。 nts河南理工大学万方科技学院本科毕业论文 Abstract The graduation design is aimed at the graduation fieldwork medium-sized crane do specific to tonnage level of design. Our country is the application of the big crane or counterfeit foreign backward technology out of manufacture and has within the plant for many years, some even application or the 70s and 80s products, both in quality and in on the function cant satisfy the growing industrial demand. How to design makes it the lowest cost, decorate rationalization, functional modernization is our topic. This design is on small tonnage design of bridge crane, the main design content is 10t bridge crane structure and operation organization, including bridge structure arrangement calculation and checking the structure of the girder, the calculation and checking, calculated and checked the beam structure, the main girders connection and cart mechanism parts selection and checking including: wheel pressure calculation and intensity checking, running friction calculation, the choice of motor, gear reducer is checked, choose speed and actual power, choose brakes, choose coupling calculating speed floating axis, buffer choice calculation, etc. And car running and lifting mechanism parts selection and checking including: running friction calculation, choose motor, choose reducer, by starting checked start-up time check reducer power, choose working brakes, choose high-speed couplings and brake wheel, the checking low-speed axial intensity, the wire rope floating choice, pulley, drum calculation, coupling choice.
