摘要

本文主要介紹了橋式起重機(jī)的整體設(shè)計(jì)理論和設(shè)計(jì)過程，其中重點(diǎn)設(shè)計(jì)了橋式起重機(jī)的運(yùn)行機(jī)構(gòu)起升機(jī)構(gòu)等，主要包括橋式起重機(jī)小車運(yùn)行機(jī)構(gòu)的整體設(shè)計(jì)及傳動機(jī)構(gòu)的布置，小車運(yùn)行機(jī)構(gòu)計(jì)算。還有軸承的選擇、聯(lián)軸器的選擇、電動機(jī)的選擇、減速器的選擇和校核。
關(guān)鍵詞：橋式起重機(jī)；起重機(jī)小車；卷筒；減速器。
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.
Keyword:Bridge type derrick;The derrick small car;Book tube;Decelerate a machine.
