毕业设计（论文）任务书

摘要

辊子输送机是一种古老的运输设备。近二十年来，由于家电等工业蓬勃兴起，各种由辊子输送机组成的生产线，装配线应运而生。这些输送机的功能因新技术、新材料的应用和各种巧妙的配套辅机而得以完善。回转轮式输送机应用于钢铁企业线材生产线的立式卷芯架输送系统，属于轧钢设备中的辅助设备。轧钢生产的发展，不仅取决于轧钢主要设备的速度的提高和轧制周期的缩短，也在很大程度上决定于轧钢辅助设备的不断完善和改进。轧钢辅助设备机械化和自动化程度以及生产能力的高低，直接影响着轧钢生产现代化的发展和生产率的提高。轧钢辅助设备在轧钢生产中起着十分重要的作用。

本次设计主要是机动旋转转台部分的设计。从驱动、传动以及零部件的类型、结构、材料和润滑密封等多方面进行方案讨论，最终选择最佳方案。

本次设计通过减速电机的驱动以及齿轮传动、链传动的传动方式，加上接触器的使用，来实现了全自动的转向输送，改变了过去依靠人力来实现的方式，大大提高了生产效率。

关键词：辊子输送机，减速电机，旋转台，辊道，链传动

Abstract

Roller conveyor is a kind of ancient transportation equipment. Over the past twenty years, such as home appliances industry booming, various composed of roller conveyor line, assembly line arises at the historic moment. The function of the conveyor is perfected with the application of new technology, new material and a variety of ingenious matching auxiliaries. Rotary roller conveyor is used in steel wire rod production line of vertical roll core business frame transmission system, belonging to the auxiliary equipment of steel rolling equipment. The development of steel rolling production, not only depends on the improvement of the speed of the main equipment of steel rolling and rolling cycle shortened, also to a large extent depends on the continuous improvement of the auxiliary equipment of steel rolling and improvement. Auxiliary equipment of steel rolling mechanization and automation as well as the production capacity of high and low, directly affects the development of modern steel rolling production and the improvement of productivity. Auxiliary equipment of steel rolling in the steel rolling production plays a very important role.

The motor rotating turntable is the main part of the design. From the drive, transmission and the types of components, structure, material and lubrication sealing solution discussion, finally choose the best scheme.

This design uses gear motor drive and gear transmission, chain drive, coupled with the use of contactor, to realize the automatic steering transmission, changed the way the past rely on manpower to implement, greatly improving the production efficiency.

Keywords: roller conveyor，deceleration motor，rotating table，roller，chain drive
