转炉炼钢车间电动过跨车的设计(含零件图和装配图)(17000字)
摘 要
本文所研究的内容是转炉炼钢车间电动过跨车的设计，这种过跨车也叫铁水过跨车，是炼钢车间里普遍使用的一类冶金车辆，它的作用是通过铁水罐，将炼钢炉内熔炼的铁水运送出，用于下一道工序生产。
本文主要分为过跨车动力系统设计和运动系统设计，其中运动系统的设计为重点。在运动系统中又主要是车体和运行机构的设计，包括端梁、横梁、铁水罐支撑架等主要车体部件以及运行机构中传动轴的尺寸设计。车体主要使用钢板焊接，浮动轴采用普通机械切削方法加工。此外，本文内容还包括车体和零件的强度校核以及稳定性验算，以确保所设计出的产品有良好的稳定性和较强的适用性。动力系统中使用三级圆柱-圆锥齿轮减速器，并采用减速器外置的设计方案。
以上设计主要依靠经验法和根据力学公式计算的方法确定尺寸并进行校核验算的，同时在设计过程中引入产品优化设计的理念，以提高产品性能降低成本。
在转炉炼钢车间电动过跨车的设计过程中，充分体现了在现有理论基础上突破创新的理念，并且设计出的产品具有承载量大、实用性强、操作简便、工作安全可靠、便于维护等特点。

ABSTRACT
What this thesis investigates is designing converter steel-making plant electromotion, with anther name molten iron cross-train. The cross-train is a kind of metallurgy vehicle, which is commonly used in steel-train. It can carry the melten iron from steel-making furnace to the next place, which is ready for the further working.
This thesis is mainly divided into two parts: power system design and locomotion system design. And the locomotion system design is the most important one. In this system, bodywork and moving mechanism design is the keystone which include the dimensions design of the transmission shaft and the main spare parts as the end-girder, the crossbeam, the nog of molten iron jar and so on. Bodywork is jointed by armor plate, and transmission shaft is adopted common mechanical cutting to process. Moreover, the content of this thesis also includes intensity checking and stability checking to make sure that the production has better stability and applicability. Two grade bevel-cylindrical gear reductor outside is used in the power system .
The dimensions are determined and the strength is checking out by the method of experience and the mechanics formula. At the same time, introducing the philosophy of optimum design to improve the production’s capability and to reduce costs.
In the research, the design concept of innovating present theory foundation is fully reflected, and the designed production has some good characteristics: more loading capacity, more practical, simple operation, safe and reliable, easy maintenance, and so on.
Keywords: cross-train, molten iron jar, mechanism design
