Planetary gear reducer gear reducer than the normal small size, light weight, high efficiency and transmission power range, etc, widely applied gradually. At the same time its drawbacks are: material quality, plex, high precision manufacturing, more difficult to install, design plex calculations than the average speed reducer. but on the planet as people drive technology further indepth understanding and knowledge as well as the introduction of foreign planetary transmission and absorption of technology to drive the structure and contain its way are constantly improving, and continuously improve the level of 東北大學(xué)秦皇島分校畢業(yè)設(shè)計(jì)（論文） 第 45 頁production technology, can produce a better planetary gear reducer[17]. According to a general load of gear strength, geometric dimensions of the design calculation, and then to carry out transmission ratio conditions, concentric condition, the assembly conditions, design and calculation of the adjacent conditions, thanks to the number of planetary gear transmission, also must be contained institutions and the design of floating volume calculation. Planetary gear drive according to the position of basic enough pieces can be divided into: 2KH, 3K, and KHV are three. If the meshing of gears by the way, can be divided into: NGWtype, NNbased, WWtype, WGW type, NGWN type and Ntype and so on. I designed planetary gear is 2KH NGW planetary transmission type.⑥ Local deceleration machine much with the wheel gear spread to move, the pole spread to move for lord, but widespread exist power and weight ratio small, or spread to move ratio big but the machine efficiency lead a low are also many weaknesses on material quality and craft level moreover, the especially large deceleration machines problem is more outstanding, the service life isnt deceleration machine of abroad, with Germany, Denmark and Japan be placed in to lead a position, occupying advantage in the material and the manufacturing craft specially, decelerating the machine work credibility like, service life it spreads to move a form to still take settling stalk wheel gear to spread to move as lord, physical volume and weight problem, dont also resolve likeThe direction which decelerates a machine to is the facing big power and spread to move ratio, small physical volume, high machine efficiency and service life to grow greatly nowadays the connecting of machine and electric motor body structure is also the form which expands strongly, and have already produced various structure forms and various products of power model close to ten several in the last yearses, control a technical development because of the modern calculator technique and the number, make the machine process accuracy, process an efficiency to raise consumedly, pushed a machine to spread the diversification of movable property article thus, the mold piece of the whole machine kit turns, standardizing, and shape design the art turn, making product more fine, the beauty turns.Bee a set a machine material in 21 centuries medium, the wheel gear is still a machine to spread a dynamic basic tool machine and the craft technical development, pushed a machine to spread to move structure to fly to develop 東北大學(xué)秦皇島分校畢業(yè)設(shè)計(jì)（論文） 第 46 頁spreading to move the electronics control, liquid in the system design to press to spread to move, wheel gear, take the mixture of chain to spread to move, will bee bee soon abox to design in excellent turn to spread to move a bination of academics that is in spread move the design crosses, will bee new spread a movable property article the important trend of the development.Essential character：Reduction gear、 Bearing 、gear 、mechanical driveMain body of the article[18]. 中文譯文 刮板輸送機(jī)刮板輸送機(jī)是一種撓性牽引的連續(xù)輸送機(jī)械，是為采煤工作面和采區(qū)巷道運(yùn)煤布置的機(jī)械。它的牽引機(jī)構(gòu)是刮板鏈，承載裝置是中部槽，刮板鏈安裝在中部槽的槽面。中部槽沿運(yùn)輸路線全線鋪設(shè)，刮板鏈繞經(jīng)機(jī)頭、機(jī)尾的鏈輪接成封閉形置于中部槽中，與滾筒采煤機(jī)和輸送機(jī)推移裝置配套，實(shí)現(xiàn)落煤、裝煤、運(yùn)煤及推移輸送機(jī)械化。沿輸送機(jī)全長(zhǎng)都可向溜槽中裝煤，裝入中部槽中的煤被刮板鏈拖拉，在中部槽內(nèi)滑行到卸載端卸下。 一般的刮板輸送機(jī)能在25176。以下的條件使用。刮板輸送機(jī)在使用中要受拉、壓、彎曲、沖擊摩擦和腐蝕等多種作用，因此，必須有足夠的強(qiáng)度、剛度、耐磨和耐腐蝕性。由于它的運(yùn)輸方式是物料和刮板鏈都在槽內(nèi)滑行，因此運(yùn)行阻力和磨損都很大。但是，在采煤工作面運(yùn)煤，目前還沒有更好的機(jī)械可代替，只能從結(jié)構(gòu)上、強(qiáng)度上和制造工藝上不斷研究，使它更加完善、耐用。 刮板輸送機(jī)是與大型綜采工作面設(shè)備配套使用的液壓支架、采煤機(jī)，完成把工作面采煤機(jī)采下的煤輸送、轉(zhuǎn)運(yùn)到后續(xù)運(yùn)輸設(shè)備上的任務(wù)，并提供相應(yīng)的連接手段。設(shè)計(jì)要求與ZY2300轉(zhuǎn)載機(jī)自移機(jī)尾配套。與ZY2300轉(zhuǎn)載機(jī)自移機(jī)尾配合可更方便地調(diào)節(jié)皮帶機(jī)，增強(qiáng)了輸送機(jī)與轉(zhuǎn)載機(jī)配合的協(xié)調(diào)性。本刮板輸送機(jī)與MG300/700WD采煤機(jī)配套使用，運(yùn)量可達(dá)1000t/h，技術(shù)先進(jìn)， 東北大學(xué)秦皇島分校畢業(yè)設(shè)計(jì)（論文） 第 47 頁工作可靠，：① 瞬時(shí)傳動(dòng)比恒定、工作平穩(wěn)、傳動(dòng)準(zhǔn)確可靠，可傳遞空間任意兩軸之間的運(yùn)動(dòng)和動(dòng)力；② 適用的功率和速度范圍廣；③ 傳動(dòng)效率高.④ 工作可靠、使用壽命長(zhǎng)；⑤ 外輪廓尺寸小、軸、軸承及箱體組成的齒輪減速器,用于原動(dòng)機(jī)和工作機(jī)或執(zhí)行機(jī)構(gòu)之間,起匹配轉(zhuǎn)速和傳遞轉(zhuǎn)矩的作用,在現(xiàn)代機(jī)械中應(yīng)用極為廣泛.行星輪系減速器較普通齒輪減速器具有體積小、重量輕、效率高及傳遞功率范圍大等優(yōu)點(diǎn)，：材料優(yōu)質(zhì)、結(jié)構(gòu)復(fù)雜、制造精度要求較高、安裝較困難些、從而使其傳動(dòng)結(jié)構(gòu)和均載方式都不斷完善，同時(shí)生產(chǎn)工藝水平也不斷提高，完全可以制造出較好的行星齒輪傳動(dòng)減速器.根據(jù)負(fù)載情況進(jìn)行一般的齒輪強(qiáng)度、幾何尺寸的設(shè)計(jì)計(jì)算，然后要進(jìn)行傳動(dòng)比條件、同心條件、裝配條件、相鄰條件的設(shè)計(jì)計(jì)算，由于采用的是多個(gè)行星輪傳動(dòng)，還必須進(jìn)行均載機(jī)構(gòu)及浮動(dòng)量的設(shè)計(jì)計(jì)算.行星齒輪傳動(dòng)根據(jù)基本夠件的組成情況可分為：2KH、3K、又可分為：NGW型、NN型、WW型、WGW型、NGWN型和N型等.國內(nèi)的減速器多以齒輪傳動(dòng)、蝸桿傳動(dòng)為主，但普遍存在著功率與重量比小，材料品質(zhì)和工藝水平上還有許多弱點(diǎn)，特別是大型的減速器問題更突出，以德國、丹麥和日本處于領(lǐng)先地位，特別在材料和制造工藝方面占據(jù)優(yōu)勢(shì)，減速器工作可靠性好，體積和重量問題，也未解決好.當(dāng)今的減速器是向著大功率、大傳動(dòng)比、小體積、高機(jī)械效率以及使用壽命長(zhǎng)的方 東北大學(xué)秦皇島分校畢業(yè)設(shè)計(jì)（論文） 第 48 頁，也是大力開拓的形式，,由于近代計(jì)算機(jī)技術(shù)與數(shù)控技術(shù)的發(fā)展，使得機(jī)械加工精度，加工效率大大提高，從而推動(dòng)了機(jī)械傳動(dòng)產(chǎn)品的多樣化，整機(jī)配套的模塊化，標(biāo)準(zhǔn)化，以及造型設(shè)計(jì)藝術(shù)化，使產(chǎn)品更加精致，美觀化.在21世紀(jì)成套機(jī)械裝備中,、液壓傳動(dòng)、齒輪、帶鏈的混合傳動(dòng),將成為新型傳動(dòng)產(chǎn)品發(fā)展的重要趨勢(shì).其中的部件
