桥式起重机 起重机运行机构运算论文.doc

摘 要 桥式起重机可分为普通桥式起重机、简易梁桥式起重机和冶金专用桥式起重机三种。普通桥式起重机一般由起重小车、桥架运行机构、桥架金属结构组。起升机构包括电动机、制动器、减速器、卷筒和滑 关键词 ：起重机， 电动机 ，减速器 ABSTRACT The cranes can be divided into normal bridge cranes, simple cranes and metallurgical special bridges cranes. Normal cranes usually by lifting the car was running, bridges, metal construction of bridges. the bridge in lifting vehicles as an important component of a crane。Promotion agencies, including a car and run the institutions , and so ang。Up promotion agencies including motor, the brake, gearand belts and pulleys.The curriculum design is primarily directed at the bridge, the cranes up the promotion of the motors, motor cars and related structures of gear.And further to the results have made.The curriculum design is to meet the longevity work，To choose the electric motor and gear by the guide. Keywords ：cranes ，motor ，reducer 目 录 第1章引言·························································1 第2章起重机介绍···················································2 2.1起重机定义······················································2 2.2起重机的类型····················································2 2.3桥式起重机定义··················································2 2.4桥式起重机分类··················································2 第3章电动机和减速器的选择··········································6 3.1电动机和减速器的简介············································6 3.2计算条件························································6 3.3 选择起升机构电动机与减速器······································7 3.3.1主起升电动机与减速器的选择····································7 3.3.1.1主起升电动机的选择··········································7 3.3.1.2主起升减速器的选择··········································8 3.3.2副起升电动机与减速器的选择···································10 3.3.2.1副起升电动机的选择·········································10 3.3.2.2副起升减速器的选择·········································11 3.4选择大车运行机构电动机与减速器·································12 3.4.1电动机的选择·················································12 3.4.2减速器的选择········································
