2、意義；國(guó)內(nèi)外研究概況、水平和發(fā)展趨勢(shì)；應(yīng)用前景等）（1）課題科學(xué)意義由于調(diào)度絞車體積小重量輕，搬運(yùn)方便，牽引力大，使用靈活，性能可靠性高，在煤礦得到了廣泛使用。同時(shí)隨著大中型礦井的增多，煤炭產(chǎn)量的提高和大型綜采設(shè)備的使用，要求礦用小絞車在工作能力、工作效率、節(jié)能、使用壽命方面得到應(yīng)有的改進(jìn)，盡快克服目前調(diào)度絞車牽引力小，并要求具有“一機(jī)多用”的功能，以簡(jiǎn)化礦用小絞車設(shè)備的生產(chǎn)、管理及維護(hù)，減少投資費(fèi)用。調(diào)度絞車多年來國(guó)內(nèi)一直具有較高的需求量, 平均每年需求各種不同規(guī)格的絞車數(shù)萬臺(tái), 因此, 改進(jìn)質(zhì)量降低成本、研制一種具有結(jié)構(gòu)緊湊、剛性好、傳動(dòng)效率高、安裝移動(dòng)方便、啟動(dòng)平穩(wěn)、操作靈活、制動(dòng)可靠、

3、故障率低、噪音低的調(diào)度絞車具有重要意義。（2）調(diào)度絞車的研究狀況及其發(fā)展前景1. 品種：國(guó)外礦用小絞車規(guī)格比較多，適用不同場(chǎng)合，我國(guó)礦用小絞車的規(guī)格少，品種型號(hào)多而亂，也較繁雜，沒有統(tǒng)一標(biāo)準(zhǔn)1。2 .型式：從工作機(jī)構(gòu)上分，國(guó)外有單筒、雙筒及摩擦式三種，我國(guó)只有單筒一種型式。從原動(dòng)力上分，國(guó)外有電動(dòng)的、風(fēng)動(dòng)的及液壓驅(qū)動(dòng)，我國(guó)只有電動(dòng)的和少量風(fēng)動(dòng)的1。3. 結(jié)構(gòu)：我國(guó)及國(guó)外的調(diào)度絞車大多數(shù)采用行星齒輪傳動(dòng)，其傳動(dòng)系統(tǒng)、結(jié)構(gòu)簡(jiǎn)單、使用維修方便。但行星齒輪傳動(dòng)只有在載荷分配均勻情況下才能充分發(fā)揮傳動(dòng)比大、結(jié)構(gòu)緊湊、效率高、承載能力大、傳動(dòng)平穩(wěn)等優(yōu)點(diǎn)。在行星齒輪傳動(dòng)設(shè)計(jì)中均載機(jī)構(gòu)是必不可少的。均載機(jī)構(gòu)能

4、補(bǔ)償不可避免的制造誤差,使各行星齒輪均勻分擔(dān)載荷,功率均勻分流,降低載荷不均勻系數(shù),從而提高承載能力。降低噪聲,提高平穩(wěn)性和可靠性,降低齒輪的制造精度。蘇聯(lián)的產(chǎn)品體積比我國(guó)同等規(guī)格的產(chǎn)品要小。例如蘇聯(lián)規(guī)定，國(guó)家標(biāo)準(zhǔn)規(guī)定的調(diào)度絞車的軸向尺寸不大于lm，而我國(guó)現(xiàn)有的牽引力1000N以上的產(chǎn)品軸向尺寸均遠(yuǎn)遠(yuǎn)大于1m以上1。4 .產(chǎn)品性能：主要壽命、噪音、可靠性等綜合指標(biāo)與蘇聯(lián)有差距。蘇聯(lián)礦用小絞車使用壽命規(guī)定在5年以上，我國(guó)目前不具備測(cè)試手段壽命無法考核，但從對(duì)用戶的訪問中得知，壽命達(dá)不到5年，噪音也稍大1。5. 三化水平：雖然我國(guó)礦用小絞車參數(shù)系列水平優(yōu)于國(guó)外，但在標(biāo)準(zhǔn)化和通用化方面遠(yuǎn)不如發(fā)達(dá)采煤

5、機(jī)械制造國(guó)。蘇聯(lián)把調(diào)度絞車運(yùn)輸絞車等統(tǒng)一為一個(gè)標(biāo)準(zhǔn)中，主機(jī)相同。只是制造和操作部分有所區(qū)別，而我國(guó)既使是同一規(guī)格產(chǎn)品，不同廠家生產(chǎn)的其結(jié)構(gòu)各不相同，零件無通用之處，給使用和選型造成不便1。 研究?jī)?nèi)容此設(shè)計(jì)進(jìn)行了調(diào)度絞車的方案設(shè)計(jì)，并進(jìn)行了比較分析，對(duì)其結(jié)構(gòu)和主要部件經(jīng)行了設(shè)計(jì)及強(qiáng)度校核。并對(duì)絞車的控制電路進(jìn)行了設(shè)計(jì)。擬采取的研究方法、技術(shù)路線、實(shí)驗(yàn)方案及可行性分析 1、零件的分析，其中包括零件的功用分析和零件的工藝分析。 2、零件工藝規(guī)程設(shè)計(jì)，其中包括確定毛坯的制造形式、定位基準(zhǔn)的選擇、擬定零件加工的工藝路線、機(jī)械加工余量、工序尺寸及毛坯尺寸的確定、確定切削用量及基本工時(shí)。3、實(shí)驗(yàn)完全以數(shù)據(jù)為

9、winch. Commonly used in the mine tunnel in the haulage and supporting mine car handling、 can also be used in the mining face、 with scheduling space station、 heavy cars. Scheduling winch is full-gear transmission machinery. Gear also known as the round of the transmission system. According round of t

10、he transmission gear when the axis of space in the relative position is fixed、 can be divided into fixed and working capital of the axis round of the round. Another round of the axis of cylindrical mesh gear transmission and the cylindrical mesh gear transmission of points、 and turnover of another r

11、ound of transmission and differential planetary transmission of the points. Scheduling the winch within the existing transmission gear meshing cylindrical Gear、 another planetary transmission、 scheduling winch planetary transmission gear、 also known as the winch. Scheduling winch models commonly use

12、d mainly JD-0.4 (JD-4.5)、 JD-1 (JD) -11.4)、 JD-1. (JD-22)、 JD-2 (JD-25)、 JD-3 (JD - 40). Below the JD-3 (that is、 JD-40) as an example of scheduling winch on the composition and scheduling transmission principle. (A) JD-3-scheduling of the winch JD-3-scheduling the main component of the winch drum f

13、or、 brakes and motor frame. From the winch drum made of cast steel、 its main function is winding rope traction load. Drum、 and the slowdown in gear with the gear. Winch on the two groups with a total installed-gate that is Brake 2、the gateway 3. Motor side of the gate 2 to brake drum brakes、 the gea

14、r in the work of three gates used to control Z7 group functioning. Use made of cast iron frame、 the motor bearings and gates with stent-positioning are fixed with bolts in the plane seat. For Flameproof for the thee-phase motor .(B) JD-3-Dispatch winch the drive principle this type of winch used two

15、 Internal Drives and a planetary gear transmission. Z1/Z2 and Z3/Z4 for two Internal Drive、 Z5、 Z6、 Z7 composition of planetary transmission mechanism. Motor head in the installation of a 5-axis extended sets of gear Z1、 through the gears Z2、 with gear Z3 and Z4、 the movement spread to gear Z5、 the

16、Z5 is the planetary gear wheel of a central round (or round of the Sun) And then led the two planetary gear Z6、 and the gear Z7. Planetary gear freely installed in the two driven and connected to a fixed axis、 the largest in the gear Z7 Gear work with the external gateway、 used to control winch drum

17、 operation. If the big gear Z7 gate on the work of three gates to live、 and will be on the brake drum gates 2 release、 this time by two motor rotation within the rodents to gear wheel drive Z5、 Z6 and Z7. However、 due to Z7 gate has been living and can not rotate、 so gear Z6 only on the one hand aro

18、und its own axis of rotation、 but also around the axis of gear Z5 (drum center) to the public. Thus connected with the rotation of the lead、 then Z6 the operation mode very similar to the planets in the solar system (such as Earth) movement、 also known as the planetary gear Z6、 its transmission mode

19、 known as the planetary transmission. Conversely、 if the gear Z7 in the work release gate 3、 and will brake drum on the live gate 2、 the Z6 directly connected with the drum、 only for the rotation、 not revolution、 the Z1 from the transmission system changed to Z7 For the fixed axis of the round、 gear

52、及其結(jié)構(gòu)特點(diǎn)調(diào)度絞車是常用來調(diào)度車輛及進(jìn)行輔助牽引作業(yè)的一種絞車。常用于礦井巷道中拖運(yùn)礦車及輔助搬運(yùn)，也可用在采掘工作面、裝車站調(diào)度空、重載礦車。 調(diào)度絞車是一種全齒傳動(dòng)機(jī)械。齒輪傳動(dòng)系統(tǒng)又稱輪系。根據(jù)輪系傳動(dòng)時(shí)各齒輪軸線在空間的相對(duì)位置是否固定，可分為定軸輪系和周轉(zhuǎn)輪系。定軸輪系又有外嚙合圓柱齒輪傳動(dòng)和內(nèi)嚙合圓柱齒輪傳動(dòng)之分，而周轉(zhuǎn)輪系又有差動(dòng)傳動(dòng)和行星傳動(dòng)之分。調(diào)度絞車的傳動(dòng)齒輪既有內(nèi)嚙合圓柱齒輪傳動(dòng)，又有行星傳動(dòng)，所以調(diào)度絞車又稱內(nèi)齒輪行星傳動(dòng)絞車。 調(diào)度絞車常用型號(hào)主要有JD0.4(JD4.5)、JD1（JD）11.4）、JD1.（JD22）、JD2（JD25）、JD3（JD40）等。

53、 下面以JD3（即JD40）型調(diào)度絞車為例介紹調(diào)度絞車的組成及傳動(dòng)原理。 （一）JD3型調(diào)度絞車的組成 JD3型調(diào)度絞車的主要組成部分為滾筒、制動(dòng)裝置機(jī)座和電動(dòng)機(jī)。絞車滾筒由鑄鋼制成，其主要功能是纏繞鋼絲繩牽引負(fù)荷。滾筒內(nèi)和大內(nèi)齒輪下裝有減速齒輪。 絞車上共裝有兩組帶式閘，即制動(dòng)閘2，工作閘3。電動(dòng)機(jī)一側(cè)的制動(dòng)閘2用來制動(dòng)滾筒，大內(nèi)齒輪上的工作閘3用于控制Z7組運(yùn)轉(zhuǎn)。 機(jī)座用鑄鐵制成，電動(dòng)機(jī)軸承支架及閘帶定位板等均用螺栓固定在機(jī)座上。電動(dòng)機(jī)為專用隔爆三相籠型電動(dòng)機(jī)。 （二）JD3型調(diào)度絞車的傳動(dòng)原理 該型絞車采用兩級(jí)內(nèi)嚙合傳動(dòng)和一級(jí)行星輪傳動(dòng)。Z1/Z2和Z3/Z4為兩級(jí)內(nèi)嚙合傳動(dòng)，Z5、Z6

54、、Z7組成行星傳動(dòng)機(jī)構(gòu)。 在電動(dòng)機(jī)5軸頭上安裝著加長(zhǎng)套的齒輪Z1，通過內(nèi)齒輪Z2、齒輪Z3和內(nèi)齒輪Z4，把運(yùn)動(dòng)傳到齒輪Z5上，齒輪Z5是行星輪系的中央輪（或稱太陽輪），再帶動(dòng)兩個(gè)行星齒輪Z6和大內(nèi)齒輪Z7。行星齒輪自由地裝在2根與帶動(dòng)固定連接的軸上，大內(nèi)齒輪Z7齒圈外部裝有工作閘，用于控制絞車滾筒運(yùn)轉(zhuǎn)。 若將大內(nèi)齒輪Z7上的工作閘3閘住，而將滾筒上的制動(dòng)閘2松開，此時(shí)電動(dòng)機(jī)轉(zhuǎn)動(dòng)由兩級(jí)內(nèi)嚙輪傳動(dòng)到齒輪Z5、Z6和Z7。但由于Z7已被閘住，不能轉(zhuǎn)動(dòng)，所以齒輪Z6只能一方面繞自己的軸線自轉(zhuǎn)，同時(shí)還要繞齒輪Z5的軸線（滾筒中心線）公轉(zhuǎn)。從而帶動(dòng)與其相連的帶動(dòng)轉(zhuǎn)動(dòng)，此時(shí)Z6的運(yùn)行方式很類似太陽系中的行星（如地球）的運(yùn)動(dòng)方式，齒輪Z6又稱行星齒輪，其傳動(dòng)方式稱為行星傳動(dòng)。 反之，若將大內(nèi)齒輪Z7上的工作閘3松開，而將滾筒上的制動(dòng)閘2閘住，因Z6與滾筒直接相連，只作自轉(zhuǎn)，沒有公轉(zhuǎn)，從Z1到Z7的傳動(dòng)系統(tǒng)變?yōu)槎ㄝS輪系，齒輪Z7做空轉(zhuǎn)。倒替松開（或閘?。┕ぷ鏖l3或制動(dòng)閘2，即可使調(diào)度絞車在不停電動(dòng)機(jī)的
