内容简介：

摘 要刮板输送机是一种挠性牵引的连续输送机械，是为采煤工作面和采区巷道运煤布置的机械。它的牵引机构是刮板链，承载装置是中部槽，刮板链安装在中部槽的槽面。中部槽沿运输路线全线铺设，刮板链绕经机头、机尾的链轮接成封闭形置于中部槽中，与滚筒采煤机和输送机推移装置配套，实现落煤、装煤、运煤及推移输送机械化。沿输送机全长都可向溜槽中装煤，装入中部槽中的煤被刮板链拖拉，在中部槽内滑行到卸载端卸下。一般的刮板输送机能在25以下的条件使用。刮板输送机在使用中要受拉、压、弯曲、冲击摩擦和腐蚀等多种作用，因此，必须有足够的强度、刚度、耐磨和耐腐蚀性。由于它的运输方式是物料和刮板链都在槽内滑行，因此运行阻力和磨损都很大。但是，在采煤工作面运煤，目前还没有更好的机械可代替，只能从结构上、强度上和制造工艺上不断研究，使它更加完善、耐用。文中所设计的SGZ1000/2700型输送机传动部主要是由电动机、减速器和弹性联轴器组成。该输送机横向布置，电动机输出的动力经由一级锥齿轮、一级斜齿轮和一级行星轮系的传动，最后驱动链轮转动。减速器采用四行星太阳轮浮动结构，减小了结构尺寸，同时提高整个工作面的输送量，提高了效率。在设计过程中，对传动部的轴、传动齿轮、轴承和联接用的花键等部件进行了设计计算、强度校核。关键词：刮板输送机 ；中部槽；刮板链。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.SGZ1000/2700designed 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 d
