文档介绍:1双滚筒采煤机牵引部设计摘要MG300/690-WD型采煤机是一种多电机驱动,横向布置的交流电牵引采煤机。该机功率大,多电机横向布置,整机结构紧凑,采用交流变频调速系统,变频调速采用机载式。截割电机、牵引电机等主要元部件均可从采空区抽出,容易更换,方便维修。牵引电机输出的转矩经二级圆柱齿轮和二级行星齿轮减速器减速后,由行星架输出,通过驱动轮与行走轮相啮合,再由行走轮与工作面刮板输送机上的齿轮啮合使采煤机来回行走,同时制动轴输出轴通过键与制动器相连,实现电牵引部的制动。左右牵引部,中间电控箱的联结螺栓,定位销,摇臂与左右电牵引部铰接销轴四组,这些装置将采煤机各大部件联接成一个整体,起到紧固及连接的作用。牵引箱与行走部独立箱体设计,配套适应性强。MG300/690-WD型采煤机,操作方便,可靠性高,事故率低,开机效率高,可满足高产高效工作面的需要。关键词:采煤机;牵引部;行走部;行星齿轮2DoubledrumshearerhaulageunitdesignABSTRACTTheMG300/900-WDcoalminingmachineismorethanonekindofmotor-driven,,themulti-electricalmachinerycrosswisearrangement,pact,usestheexchangefrequencyconversionvelocitymodulationsystem,thefrequencyconversionvelocitymodulationusesaircraft-borne-,thepullingmotorandsoonmainparttobepossibletoextractfromtheworked-outsection,easytoreplace,-levelcylindricalgearsandthesecond-gearreductiongear,carrieroutputs,withwalksliningonthefeetandpalmsofBuddhameshingthroughthedrivinggear,bywalksagainroundandonworkingsurfacescraperconveyer’srackrailmeshingcausesthecoalminingmachinebackandforthtowalk,simultaneouslythebrakespindleoutputshaftisconnectedthroughthekeyandthebrake,,themiddleelectricallycontrolledbox’sjointstud,thepositioningpin,therockingshaftsellstheaxisfourgroupswithaboutelectricityhaulingdepartmenthinge,theseinstallmentsjoincoalminingmachinevariousmajorassembliesawhole,,patibilityTheMG300/900-WDcoalminingmachine,theeaseofoperation,thereliabilityishigh,identrateislow,thestartingefficiencyishigh,:Thecoalminingmachine;Thehaulingdepartment;Walks;,技术的创新,煤炭生产进入高产、高效、安全和可靠的现代化发展阶段。从此,综合机械化采煤设备成为各国地下开煤矿的发展方向。自70年代以来,综合机械化采煤设备朝着大功率、遥控、遥测方向发展,其性能日臻完善,生产率和可靠性进一步提高。工矿自动检测、
