摘 要
G400/930-AWD型采煤機是一種多電機驅(qū)動,橫向布置的交流電牽引采煤機。該機功率大,多電機橫向布置,整機結(jié)構(gòu)緊湊,采用交流變頻調(diào)速系統(tǒng),變頻調(diào)速采用機載式。截割電機、牽引電機等主要元部件均可從采空區(qū)抽出,容易更換,方便維修。
牽引電機輸出的轉(zhuǎn)矩經(jīng)三級圓柱齒輪和二級行星齒輪減速器減速后,由行星架輸出,通過驅(qū)動輪與行走輪相嚙合,再由行走輪與工作面刮板輸送機上的齒軌嚙合使采煤機來回行走,同時制動軸輸出軸通過鍵與制動器相連,實現(xiàn)電牽引部的制動。
左右牽引部,中間電控箱的聯(lián)結(jié)螺柱,定位銷,搖臂與左右電牽引部鉸接銷軸四組,這些裝置將采煤機各大部件聯(lián)接成一個整體,起到緊固及連接的作用。牽引部與行走部做成一體,使機身整體尺寸緊湊,縮小了機身寬度。
G400/930-AWD型采煤機,操作方便,可靠性高,事故率低,開機效率高,可滿足高產(chǎn)高效工作面的需要。
關(guān)鍵詞:采煤機;牽引部;行走部;行星齒輪
ABSTRACT
The G400/930-AWD coal mining machine is more than one kind of motor-driven, crosswise arrangement alternating current hauling coal mining machine. This machine power is big, the multi-electrical machinery crosswise arrangement, the complete machine structure is compact, uses the exchange frequency conversion velocity modulation system, the frequency conversion velocity modulation uses aircraft-borne -like. Cuts the electrical machinery, the pulling motor and so on main part to be possible to extract from the worked-out section, easy to replace, facilitates the service.
The pulling motor outputs torque decelerates after the third-level cylindrical gears and the second-level planet gear reduction gear, by the planet carrier outputs, with walks lining on the feet and palms of buddha meshing through the driving gear, by walks again round and on working surface scraper conveyer's rack rail meshing causes the coal mining machine back and forth to walk, simultaneously the brake spindle output shaft is connected through the key and the brake, realizes the electricity hauling department brake.
About the hauling department, the middle electrically controlled box's joint stud, the positioning pin, the rocking shaft sells the axis four groups with about electricity hauling department hinge, these installments join coal mining machine various major assemblies a whole, plays the fastening and the connection role. The hauling department with walks to make a body, caused the fuselage overall size to be compact, reduced the fuselage width.
The G400/930-AWD coal mining machine, the ease of operation, the reliability is high, the accident rate is low, the starting efficiency is high, may satisfy the high production highly effective working surface the need.
Key word: The coal mining machine; the hauling department; walks;Planet gear
