摘    要

      本说明书主要介绍了输送机传动部的设计计算。SGZ1000/3000 型输送机传动部主要是由一个电动机、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二级齿轮和一级行星轮系的传动，最后驱动链轮转动。减速器采用四行星单浮动结构，减小了结构尺寸，采用三驱动大功率设计，可以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、强度校核和选用。本说明书主要针对主要部件的设计计算和强度校核进行了叙述和介绍。
此外，还对SGZ1000/3000型输送机的使用与维护进行了说明，以便能更好的发挥该输送机的性能，达到最佳工作效果。

ABSTRACT

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 SGZ1000/3000 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 the course of designing, to cutting the axle of the cutting department, gear wheel of the transmission, parts such as the bearing and spline linking using,etc have designed to calculate, the intensity is checked and selected for use. This manual mainly designs for main part one calculating to check with the intensity have narrated and introduced.
In addition，returning use for SGZ1000/3000 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.
