160T过跨车的设计

摘要

随着钢铁工业突飞猛进的发展，冶炼方法及冶炼设备也在逐步得以改进。特别是转炉炼钢在我国的发展速度很快，转炉的钢产量和品种不断增加，转炉的容量也在不断扩大。为了提高生产效率，降低能耗，减轻工人劳动强度，保证在几十分钟内炼出合格的钢水，转炉设备及其辅助设备都必须具有较高的机械化和自动化水平。本篇论文，首先整理了有关于铁水车和钢水车的资料，了解铁水车的种类、特点以及其应用范围，工作原理和结构特点。并且论述了铁水车和钢水车在国内外的应用情况及发展趋势。然后对本次设计的160T铁水过跨车的行走机构进行设计。行走机构由电动机、传动装置、联轴器、传动轴、车轮组和制动器所组成。首先，确定过跨车的行走速度以及总重量。然后，根据行走速度以及总重量确定走行机构的电动机和减速器，选择行走机构传动系统的联轴器、制动器、轴承，以及行走机构的轨道和车轮。最后，对所选的电动机、减速器的齿轮、轴、轴承等重要零件进行校核,确定润滑方式以及分析环保和经济性。

The Design of The 160T Hot Metal Cross Car

Abstract

With the rapid development of the iron and steel industry, smelting and refining equipment has gradually improved. Particularly,BOF in our country is developing rapidly, the converter steel production and varieties is increasing,the capacity of converter is also expanding. In order to improve productivity and reduce energy consumption, reduce labor intensity of workers, and ensure smelting qualified molten stell in a few minutes, converter equipment and auxiliary equipment must have a higher level of mechanization and automation.In this paper, first of all,collect information of the molten hot metal cars and trucks,understanding the types of hot metal cars, characteristics and scope of its application, the working principles and structural features. And discusses the molten hot metal cars and trucks application and development trends at home and abroad.Then,design the walking mechanism of this 160T hot metal cross car.Walking mechanism fromed by the motor, gear, coupling, shaft, wheel and brake. Firstly, identify the walking speed and total weight of the hot metal cross car.secondly, based on the total weight and walking speed,design the motor and reducer of the walking mechanism,select the couplings,brakes and bearings of the  walking mechanism transmission system, and the track and wheels of the walking mechanism. Finally, check the selected motors, gear reducers, shafts, bearings and other important parts, as well as determine the lubrication mode and analysis of environmental protection and economy.
