摘  要

刮板输送机是综合机械化采煤工作面的主要运输设备。它的作用一是把采煤机破碎下来的煤运到顺槽转载机；二是作为采煤机行走的轨道以及液压支架前移的支点。
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。
本说明书主要介绍了输送机的选型和传动部的设计计算。本设计以SGZ764/264型输送机参考，不依赖于764系列输送机， 本设计采用较低转速的防爆电动机，旨在降低高速轴的转速，减少单位时间内应力循环次数；传动部主要是由两个电动机、减速箱和液力偶合器组成，该输送机内横向布置，电动机输出的动力经由三级齿轮的传动，最后驱动链轮转动。

           Abstract

     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.
Calculate in design which cuts the cutting department of main introduction scraper conveyor of this drive line. It is made up of a gearbox and moderate breeze gear wheel transmission that the type scraper conveyor cuts the cutting department, cut the electrical machinery of cutting department and put to fix up horizontally in the rocker arm, the power that the motor outputs leans on a round of transmission of department of gear wheel and planet round via the tertiary straight tooth, urge the cylinder to rotate finally. Cut the cutting department and adopt the floating structure of four planetary forms, have reduced the physical dimension, adopt the large angle to curve the rocker arm to design, have strengthened the space of coal, have improved the coal result of putting.
In addition，returning use for SGZ764/264 scraper conveyor and maintenance proves,In order to be able to good full play performance of person who should mine, reach the best working result.
