文档介绍：摘要
采煤机是机械化采煤作业的主要设备之一,牵引部是采煤机的重要部件。采煤机的牵引方式有机械牵引、液压牵引和电牵引,现在电牵引采煤机已经成为了市场上的主要产品。
本设计的目的是设计出强度满足理论要求、结构符合实际情况的682型电牵引采煤机牵引部。在本设计中,首先对牵引部进行了传动装置的总体设计与相关运动参数的计算,然后依据有关公式和标准,对各级齿轮传动、轴与轴承分别进行了设计和校核,主要是对行星结构的相关齿轮、轴和轴承进行了计算。
最后的计算结果表明:本设计得到的牵引部中的全部齿轮,行星结构中的行星轴、太阳轮、行星结构中的轴承的结构是合理的,强度也是符合安全要求的,可以投入生产和在煤矿生产中使用。

Abstract
Shearer mechanized mining operations is the main equipment of the Department of traction Shearer is an ponent. Shearer's style of mechanical traction traction, hydraulic and electric traction drive and traction Shearer, now has e the major products on the market.
The purpose of this design is designed to meet the intensity of demand, in line with the actual structure of the 682-type electric traction traction Shearer Department. In this design, the first of the Department of the traction transmission device and the overall design parameters of the relevant sports, and in accordance with the relevant formula and standards at all levels gear transmission, shaft and bearings were carried out design and verification, the main of the related gear, shaft and bearings were calculated.
The results show that the final: This design by the Department of traction in all gears, ary structure of the ary axis, the sun round, the bearing structure of the 's structure is reasonable, strength is also in line with safety requirements, and can be put into production in The use of coal mine production.
Key words: Shearer; traction Department; round of the
