【正文】 摘 要 本文主要介紹了橋式起重機的整體設計理論和設計過程 ,闡述了橋式起重機國內(nèi)外的發(fā)展狀況 .其中重點設計了橋式起重機的運行機構(gòu)和起升機構(gòu)等 ,主要包括橋式起重機小車運行機構(gòu)的整體設計及傳動機構(gòu)的布置，小車運行機構(gòu)的的計算，大車運行機構(gòu)的整體設計和橋架結(jié)構(gòu)的設計計算等。除此之外，還有軸承的選擇，聯(lián)軸器的選擇，電動機的選擇，減速起的選擇和校核。 本文設計過程中，主要采用了文獻資料法，軟件設計法和討論等方法，結(jié)合了國內(nèi)外起重機的研究發(fā)展狀況，參考了一些機加工車間所使用的起重機性能參數(shù)，從而系統(tǒng)的完成起重機的整 體設計。 關鍵詞 ：橋式起重機；起重機小車；起重機大車；運行機構(gòu)；起升機構(gòu)；橋架機構(gòu)；卷筒；減速器。浙江 大學畢業(yè)設計 2 Abstract This article mainly introduced the entire design theory and design process of bridge crane,which elaborated domestic and foreign crane development of them,it focused on the design of the bridge crane operation of institutions and hoisting overall design that mainly includes the integral design of bridge crane car mechanism and transmission layout。thecalculation of crane small car mechanism。 the integral design of the cart mechanism。and bridge structure design calculation。and so , thispaper involves bearing choice,coupling choice,motor choice,along with reducer choice and checking. In the design process of this paper, mainly adopts methods of documentation, methods of the design of hardware,and discussion were with the domestic and foreign research some machining workshop crane used performance parameters,thus the design of crane system was pleted. Keywords: Bridge crane。 Crane small car。 Crane cart。 operating mechanism。Hoisting mechanism。 Bridge institutions。 drum。reducer.浙江 大學畢業(yè)設計 3 目 錄 摘要 ....................................................................................................................... 1 Abstract ............................................................................................................... 2 第一章 緒論 ...................................................................................................... 6 概述 .......................................................................................................................... 6 橋式起重機發(fā)展概述 .............................................................................................. 6 國外橋式起重機發(fā)展動向 ......................................................................... 7 國內(nèi)橋式起重機發(fā)展動向 ......................................................................... 7 橋式起重機設計目的，設計任務，設計要求和設計參數(shù) .................................. 8 設計目的 ........................................................................................................ 8 、設計任務： ................................................................................................. 8 、設計要求 ..................................................................................................... 8 設計參數(shù) ....................................................................................................... 9 本章小結(jié) .................................................................................................................. 9 第二章 小車起升機構(gòu)設計 ............................................................................. 10 鋼絲繩 .................................................................................................................... 10 主起升鋼絲繩 ............................................................................................. 10 . 副起升鋼絲繩 ....................................................................................................... 11 滑輪組 .................................................................................................................... 11 主起升滑輪組 ............................................................................................. 12 副起升滑輪組 ............................................................................................. 12 卷筒 ........................................................................................................................ 13 主起升卷筒 ................................................................................................. 13 副起 升卷筒 ................................................................................................. 15 取物裝置 ............................................................................................ 17 取物裝置的設計方案的確定 ..................................................................... 17 取物裝置相關設計計算 ........................................................................................ 18 主吊鉤 ......................................................................................................... 18 副吊鉤 ......................................................................................................... 21 吊鉤組其他零件的計算 ........................................................................................ 24 主吊吊鉤橫梁的計算 ................................................................................. 24 浙江 大學畢業(yè)設計 4 主吊鉤拉板的校核 ..................................................................................... 25 副吊鉤橫梁的計算 ..................................................................................... 26 副吊鉤拉板的校核 ..................................................................................... 27 第三章 小車運行機構(gòu) ..................................................................................... 29 小車運行機構(gòu) ........................................................................................................ 29 確定小車傳動方案 ...................................................................................... 29 選擇車輪與軌道并驗算強度 ..................................................................... 30 運行阻力計算 ............................................................................................. 31 選擇電動機 ................................................................................................. 32 驗算電動機發(fā)熱條件 ................................................................................. 33 選擇減速器 ................................................................................................. 33 驗算運行機構(gòu) 速度和實際所需功率 ......................................................... 33
