【正文】 本科畢業(yè)設(shè)計(jì)（論文） 題目： 慢 步 卷揚(yáng)機(jī)傳動裝置設(shè)計(jì) 教學(xué)單位： 機(jī)電工程系 專 業(yè)： 機(jī)械設(shè)計(jì)制造及其自動化 學(xué) 號： 09120xx301 姓 名： 指導(dǎo)教師： 20xx 年 5 月 I 摘要 卷揚(yáng) 機(jī)廣泛應(yīng)用建筑、水利、冶金、起重作業(yè)。卷揚(yáng)機(jī)又稱絞車，是起重、垂直運(yùn)輸機(jī)械的重要組成部分，配合井架、桅桿、滑輪等輔助設(shè)備，用來提升物料、安裝設(shè)備。 電動卷揚(yáng)機(jī)由電動機(jī)、聯(lián)軸節(jié)、制動器、齒輪箱和卷筒組成，共同安裝在機(jī)架上。電動卷揚(yáng)機(jī)又可稱為電動葫蘆。對于起升高度和裝卸量大，工作繁忙的情況下，要求調(diào)速性能好，特別要空鉤能快速下降。對安裝就位或敏感的物料，要能以微動速度下降卷揚(yáng)機(jī)包括快速卷揚(yáng)機(jī)和慢速卷揚(yáng)機(jī)，僅能在地上使用，它以電動機(jī)為動力，經(jīng)彈性聯(lián)軸節(jié)，三級封閉式齒輪減速器，牙嵌式聯(lián)軸節(jié)驅(qū)動卷筒，采用電磁制動。該產(chǎn) 品通用性高、結(jié)構(gòu)緊湊、體積小、重量輕、起重大、使用轉(zhuǎn)移方便，被廣泛應(yīng)用于建筑、水利工程、林業(yè)、礦山、碼頭等的物料升降或平拖，還可作現(xiàn)代化電控自動作業(yè)線的配套設(shè)備。盡管其應(yīng)用非常廣泛 ,但在實(shí)際應(yīng)用過程中目前仍存在著許多急待解決的問題 ， 普遍存在的不足是：體積大、過載能力差、噪音大、效率低、使用壽命短、工作不夠安全可靠等，有些產(chǎn)品還已列入國家淘汰產(chǎn)品 ， 開展 卷揚(yáng)機(jī) 機(jī)設(shè)計(jì)、性能分析及應(yīng)用研究， 具有較大的實(shí)用價(jià)值和重要的現(xiàn)實(shí)意義 ，本次通過對漫步卷揚(yáng)機(jī)傳動系統(tǒng)的設(shè)計(jì)，希望能找出現(xiàn)階段所存在的問題，并提出解決方案， 以此試 圖對我國 卷揚(yáng)機(jī)的開發(fā)和改進(jìn)祈禱借鑒作用。 關(guān)鍵詞 ： 卷揚(yáng)機(jī) 。 設(shè)計(jì) 。 性能分析 。 通用性 II Abstract The widely applied in construction, water conservancy, metallurgy, lifting operation. Hoist and winch, is an important part of lifting, vertical transport machinery, with the derrick, maist is posed of motor, coupling, brake, gear box and reels, mounted on the frame. Electric hoist is also known as electric hoist. For lifting height and loading amount is large, busy with work, request good speed performance, especially to the empty hook to the rapid decline in. The installation or sensitive material, to be able to decrease the speed of fast hoist winch fretting and slow winch, can only be used on the ground, it takes the motor as power, through an elastic coupling, three closed type gear reducer, tooth type coupling drive drum, using electromagic brake. This product is high universality, pact structure, small volume, light weight, big, use convenient, it is widely used in construction, water conservancy, forestry, mining, port materials such as lifting or flat mop, ancillary equipment can be automatic line for modern electronic. Despite its very wide application, but in the actual application process still exist many urgent problems to be solved, the mon problems are: large volume, poor overload capacity, large noise, low efficiency, short service life, work is not safe, some products also has been included in the national phaseout products, carry out analysis and Research on Application of hoist machine design, performance, and has practical value and important practical significance, this time through the design of a walking drive system, hoping to find the existing problems, and puts forward the solution, in order to develop and to our hoist improved prayer reference Keyword： Windlass。 Design。 large volume。 capacity III 目錄 第 1 章 緒論 ...................................................................... 1 選題背景 .................................................................... 1 國內(nèi)外發(fā)展概況 .............................................................. 1 傳動裝置總體設(shè)計(jì)方案 ........................................................ 2 第 2 章 電動機(jī)的選擇 .............................................................. 4 ............................................................... 4 ............................................................... 4 確定電動機(jī)的轉(zhuǎn)速 ............................................................ 4 、確定傳動裝置的總傳動比和分配傳動比 ........................................ 5 總傳動比 ............................................................... 5 分配傳動裝置傳動比： ................................................... 5 計(jì)算傳動 裝置的運(yùn)動和動力參數(shù) ................................................ 5 各軸轉(zhuǎn)速 ............................................................... 5 各軸輸入功率 ........................................................... 5 第 3 章 齒輪的設(shè)計(jì) ............................................................... 7 選定齒輪類型 、精度等級、材料及齒數(shù) .......................................... 7 按齒面接觸強(qiáng)度設(shè)計(jì) .......................................................... 7 計(jì)算 ........................................................................ 8 ......................................................... 9 設(shè)計(jì)計(jì)算 ................................................................... 10 .............................................................. 11 第 4 章 蝸桿的設(shè)計(jì) ............................................................... 12 .......................................................... 12 .................................................................. 12 按齒面接觸疲 勞強(qiáng)度進(jìn)行設(shè)計(jì) ................................................. 12 ................................................................ 13 .............................................. 13 ...................................................... 14 .................................................................. 15 第 5 章 滾動軸承和傳動軸的設(shè)計(jì) ................................................... 16 .............................................................. 16 軸上的功率 ............................................................. 16 求作用在蝸桿上的力 ..................................................... 16 初步確定軸的最小直徑 ................................................... 16 根據(jù)軸向定位的要求確定軸的各段直徑和長度。 ............................. 17 求軸上的載荷 ........................................................... 18 ............................................ 19 ........................................................ 19 .............................................................. 20 IV 軸上的功率 ............................................................. 20 求作用在蝸輪上的力 ..................................................... 20 初步確定軸的最小直徑 ................................................... 20 根據(jù)軸向定位的要求確定軸的各段直徑和長度。 ............................. 21 求軸上的 載荷 ........................................................... 21 .........
