文档介绍：摘要滚筒式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三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轨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柱,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。牵引部与行走部做成一体,使机身整体尺寸紧凑,缩小了机身宽度。滚筒式采煤机,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AbstractThedrumtypeshearerisakindofmultimotordrive,,pactstructure,andtheuseofACvariablefrequencyspeedregulationsystem,,ponentscanbeextractedfromtheminedoutarea,easytoreplace,,aryframeoutput,throughthedrivingwheelandthewalkingwheel,andthenbythewalkingwheelandtheworkingfacescraperconveyoronthetracktomakethecoalminingmachinebackandforthtowalk,,ontrolbox,thepositioningpin,therockerarmandtheleftarmoftheleftandrightelectrictractionparts,thesedevicesareconnectedtothemainpartsofthecoalminingmachineintoawhole,,pact,,theoperationisconvenient,thereliabilityishigh,identrateislow,thestartingefficiencyishigh,:coalminingmachine;traction;wheel;arygear目录摘要 1ABSTRACT 2目录 31概述 162牵引部的设计、功率、转矩 533轴的设计及校核 583.
