摘 要
MG600/1400-WD型采煤機(jī)是大功率無鏈電牽引采煤機(jī)，采煤機(jī)截割部是采煤機(jī)的主要部件之一，主要承擔(dān)截煤和裝煤任務(wù)。截割部主要由箱體、原電機(jī)、輸出軸、減速部分、除塵及冷卻系統(tǒng)，潤滑系統(tǒng)等組成。采煤機(jī)截割部減速器主要由固定減速器和搖臂行星減速起兩部分組成，截割部機(jī)械傳動(dòng)由二級(jí)直齒傳動(dòng)和二級(jí)行星機(jī)傳動(dòng)實(shí)現(xiàn)，且末級(jí)采用太陽輪浮動(dòng)形式的行星傳動(dòng)。采取搖臂結(jié)構(gòu)形式以增大滾筒的過煤空間進(jìn)而提高裝煤效率；為了適應(yīng)不同的采高，通過更換一軸和二軸相應(yīng)配對齒輪可實(shí)現(xiàn)三檔變速，所實(shí)現(xiàn)工作轉(zhuǎn)速分別為30.36r/min、35.2r/min、40.6r/min。并對各級(jí)齒輪及相應(yīng)的傳動(dòng)軸進(jìn)行了設(shè)計(jì)計(jì)算和相應(yīng)的校核，繪出采煤機(jī)截割部結(jié)構(gòu)裝配總圖和主要的零部件圖，結(jié)果滿足設(shè)計(jì)要求。

Abstract
MG600/1400-WD Shearer is linked with high-power electric traction Shearer, Shearer is Shearer cutting the Department of the main components of one of the main commitments with the latest coal and coal task. Cutting mainly by box, the original motor, the output shaft, the slowdown of the dust and cooling systems, lubrication system, and other components. Shearer cutting reducer mainly by the Ministry of fixed reducer and rocker slowdown from the planet composed of two parts, cutting mechanical transmission from two straight and two planetary gear transmission for transmission to achieve, Qiemo-round use of the sun floating Forms of planetary transmission. Rocker structure to take the form of increased drum of a loaded coal space further enhance the efficiency of coal; In order to adapt to different mining, through the replacement of a shaft and four-axis corresponding matching gear third gear transmission can be realized, the work achieved by the speed were 30.36 r / min, 35.2r/min, 40.6r/min. And at all levels and the corresponding drive shaft gear for the design calculations and the corresponding check, drawn Shearer cutting assembly of the structure of the plans and major parts map, the results meet the design requirements.
