摘 要 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25°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(méi)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。 文中所設(shè)計(jì)的SGZ1000/2×700型輸送機(jī)傳動(dòng)部主要是由電動(dòng)機(jī)、減速器和彈性聯(lián)軸器組成。該輸送機(jī)橫向布置，電動(dòng)機(jī)輸出的動(dòng)力經(jīng)由一級(jí)錐齒輪、一級(jí)斜齒輪和一級(jí)行星輪系的傳動(dòng)，最后驅(qū)動(dòng)鏈輪轉(zhuǎn)動(dòng)。減速器采用四行星太陽(yáng)輪浮動(dòng)結(jié)構(gòu)，減小了結(jié)構(gòu)尺寸，同時(shí)提高整個(gè)工作面的輸送量，提高了效率。在設(shè)計(jì)過(guò)程中，對(duì)傳動(dòng)部的軸、傳動(dòng)齒輪、軸承和聯(lián)接用的花鍵等部件進(jìn)行了設(shè)計(jì)計(jì)算、強(qiáng)度校核。 關(guān)鍵詞：刮板輸送機(jī) ；中部槽；刮板鏈。 Scraper conveyor Scraper conveyor is a reprint of fully coal face ancillary equipment in the transport system an important part of the roadway in the face of the accepted face scraper conveyor unloading of coal flow, not halt the transfer to the retractable belt Conveyor boost. Bridge reversed loader with the face-scraper conveyor machine synchronous over his head, face Shearer guarantee for coal mining, and fully mechanized coal face of high yield and high efficiency operations. Scraper conveyor is a reprint of a special structure of the scraper conveyor, powertrain and drive and scraper conveyor similar to a ramp of its fuselage and a section of the arch bridge structure and belt conveyors in the tail Paragraph above lap. In the back-alley in the coal face when the machine goes to reprint its arch bridge and all of the aircraft ended the lap belt conveyor stack of position limits, a retractable belt conveyor shortened ride Next length of the belt conveyor for the development of the shift to home-unloading nose reproduced below, can be reproduced with the face of the advance goes forward. SGZ1000/2×700designed conveyor drive type mainly by a motor, reducer box and hydraulic coupling of the conveyor with the horizontal layout, electrical power output by the one planetary gears and a transmission gear the final drive sprocket rotation.Sun gear reducer with four planets floating structure, reducing the structure size, while improving the delivery of the entire face amount, to improve efficiency. In the design process, the Department of the drive shaft, transmission gears, bearings and spline connection with the design calculations and other components, strength analysis.
