毕业设计（论文）-桥式起重机的整体设计.doc

摘要 本文主要介绍了桥式起重机的整体设计理论和设计过程，其中重点设计了桥式起重机的运行机构起升机构等，主要包括桥式起重机小车运行机构的整体设计及传动机构的布置，小车运行机构计算。还有轴承的选择、联轴器的选择、电动机的选择、减速器的选择和校核。 桥式起重机是桥架型起重机的一种，它依靠起升机构和在水平面内的两个相互垂直方向移动的运行机构，能在矩形场地及其上空作业，是工矿企业广泛使用的一种起重运输机械。它具有承载能力大，工作可靠性高，制造工艺相对简单等优点。 关键词：桥式起重机；起重机小车；卷筒；减速器。 Abstract This article mainly introduced the entire design theory and design process of bridge-type hoist crane，which focused on the design of the bridge crane operation of institutions and hoisting mechanism．The overall design that mainly includes the bridge type derrick small car to circulate organization and spread the decoration that the motive reaches, the small car circulates an organization calculation.Still have the choice of the choice, electric motor of the choice, allied stalk machine of bearings, decelerate machine of choice and pit in the school. The bridge crane is a bridge-type crane, it relies on the lifting mechanism and in the horizontal plane, two mutually perpendicular direction of the run institutions, in the rectangular space over the job, the industrial and mining enterprises widely used as a startingheavy transport machinery. It has a large carrying capacity, high reliability, work, and manufacturing process is relatively simple. Keyword:Bridge type derrick;The derrick small car;Book tube;Decelerate a machine. 目 录 设计任务书---------------------------------------------------------------------------------1 第1章 概述------------------------------------------------------------------------------2 第2章 总体设计------------------------------------------------------------------------------2 2.1 总体设计方案---------------------------------------------------------7 2.2 四连杆变幅臂架系统运动学设计---------------------------------7 2.3 总体尺寸规划----------------------------------------------------7 第1章 主起升机构计算-------------------------------------------------------------7 1.1 确定传动方案，选择滑轮组和吊钩组---------------------------------7 1.2 选择钢丝绳-------------------------------------------7 1.3 确定卷筒尺寸并验算强度-------------------
