橋式起重機(jī)小車運(yùn)行機(jī)構(gòu)設(shè)計(jì)學(xué)生姓名:文華兵 班級:0781052指導(dǎo)老師:封立耀摘要:起重機(jī)的出現(xiàn)大大提高了人們的勞動(dòng)效率,以前需要許多人花長時(shí)間才能搬動(dòng)的大型物件現(xiàn)在用起重機(jī)就能輕易達(dá)到效果,尤其是在小范圍的搬動(dòng)過程中起重機(jī)的作用是相當(dāng)明顯的。在工廠的廠房內(nèi)搬運(yùn)大型零件或重型裝置橋式起重機(jī)是不可獲缺的。橋式起重機(jī)小車主要包括起升機(jī)構(gòu)、小車架、小車運(yùn)行機(jī)構(gòu)、吊具等部分。其中的小車運(yùn)行機(jī)構(gòu)主要由減速器、主動(dòng)輪組、從動(dòng)輪組、傳動(dòng)軸和一些連接件組成。此次設(shè)計(jì)的橋式起重機(jī)是水電站橋式起重機(jī),安裝于豐滿水電站擴(kuò)建工程廠房內(nèi),用于水輪發(fā)電機(jī)組及其附屬設(shè)備的安裝和檢修工作。水電站內(nèi)設(shè)備一般都是大中型設(shè)備,對橋式起重機(jī)的載荷要求較高,所以對減速器性能要求較高。關(guān)鍵詞:橋式起重機(jī) 小車運(yùn)行機(jī)構(gòu) 減速器指導(dǎo)老師簽名:Design of the bridge type hoist crane Car movement organizationStudent name:Wen Huabing Class:0781052Supervisor:Feng LiyaoAbstract: The invention of crane has greatly increased people’s work efficiency. People can use crane to handle with huge articles, which used to be taken a long time to do, especially in a small area. The bridge type hoist crane is required to handle with huge accessory or huge device.The bridge type hoist crane car consists of protmoted organization, the car frame, the car movement organization, hoisting mechanism and so on. Its driven wheel group, the transmission shaft and some connect fitting.The core of this structure is the design of the reducer.Thi bridge type hoist crane is be used to hydroelectric power station. It is installed in the expanded workshop of Fengman water and electricity station. It is used to installing ,examining and reqairing the water-turbine generator set and its accessorial equipments. The equipments in the water and electricity station are large or medium-size. These equipment have a high request on the load of bridge type hoist crane ,so they also have a high request on the capability of the reducer.Key words: bridge type hoist the reducerSignature of supervisor:
