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(guó)內(nèi)外發(fā)展概況 .............................................................. 1 傳動(dòng)裝置總體設(shè)計(jì)方案 ........................................................ 2 第 2 章 電動(dòng)機(jī)的選擇 .............................................................. 4 ............................................................... 4 ............................................................... 4 確定電動(dòng)機(jī)的轉(zhuǎn)速 ............................................................ 4 、確定傳動(dòng)裝置的總傳動(dòng)比和分配傳動(dòng)比 ........................................ 5 總傳動(dòng)比 ............................................................... 5 分配傳動(dòng)裝置傳動(dòng)比： ................................................... 5 計(jì)算傳動(dòng) 裝置的運(yùn)動(dòng)和動(dòng)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(jí)、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(dòng)軸承和傳動(dòng)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(zhǎng)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(zhǎng)度。 ............................. 21 求軸上的 載荷 ........................................................... 21 .........
