内蒙古科技大学毕业设计说明书I摘摘 要要我设计的题目是移钢机设计 。移钢机是钢管生产的一个不可缺少的部分，是用来将钢管从一个工序送到下一工序，由回转装置和 S 形拨料钩组成的。其工作原理是利用链传动，采用电机、减速器驱动。回转臂将钢管放到链式输送机，在用链式输送机把钢管输送到下一工序的台架上。本设计是以包钢无缝钢管厂的工程实例惠斯顿移钢机，旋转周期 12.5s ，可根据工作要求实现钢管的上下料而设计的，说明书的绪论部分详细介绍了我国无缝钢管产业的新格局和发展状况，分析了我国无缝钢管产业的情况。说明书正文详细阐述了惠斯顿移钢机的结构和工作原理，此移钢机的结构主要由传动机构和回转机构组成。传动机构对移钢机的正常安全运行有着重要的作用，而回转机构的回转半径影响着钢管的移钢距离。在设计计算中，说明书中首先根据力能公式计算出电动机的有效功率，然后再根据有效功率功率选择电动机，并介绍了选用电动机原则；根据传动比选择减速器的类型和型号，并对减速器的润滑做了简单的介绍；根据传动方案设计直齿圆柱齿轮传动，并对齿轮进行强度校核；还进行了轴的结构设计以及轴的强度校核，最后对轴承、联轴器和制动器等一些零件进行选择以及安全校核。经过上面一系列的设计计算及校核，设计出的移钢机便可以正常安全的工作。关键词：关键词：移钢机 回转机构 传动方案内蒙古科技大学毕业设计说明书IIAbstractAbstractI designed the titleShift Steel Machine 。Shift steel pipe production line machine is an indispensable part of the pipe from one process to an important tool for the next process, mainly by the rotating device and S-shaped hook material composed of dial. Its power source for the motor，speed reducer and chain through their work. Rotating steel arm will be put on the chain conveyor, chain conveyor from the process pipe to the next bench. The design is based on the current steel seamless steel pipe plant equipment Whiston Steel shift-based machine (the rotation period of 12.5s) in accordance with the requirements to achieve the top and bottom of pipe material and design. Part of a detailed introduction on Chinas new pattern of seamless steel pipe industry and development，an analysis of the status quo of our seamless steel tube industry. Elaborated on the main body of the shift Whiston Steel Structure and working principle. This changed the structure of steel machine by rotary drive mechanism and institutions. Steel shift transmission is the normal operation of an effective local power source, and turning radius of gyration of the body affects the transfer of steel from the steel pipe。Calculation in the design, first of all force and energy in accordance with the formula to calculate the effective power and then electrical power in accordance with effective power to choose motor and electric motor, introduced the principle of selection; according to transmission requirements and the working environment to choose the type and model reducer and reducer lubrication so brief; in accordance with the design of transmission and the spur gear shaft and gear and shaft for strength checking; Finally, bearings, couplings and brake parts and other options as well as the safety check carried out. After a series of design, calculation and check, and ultimately come to this theory, the design of steel plane shift to meet the conclusions of the safe use of the site.内蒙古科技大学毕业设计说明书IIIKey words: Shift Steel Machine Slewing Mechanism Transmission program内蒙古科技大学毕业设计说明书IV目 录摘 要.IAbstract.II第一章 绪论.11.1 我国无缝钢管行业的发展趋势.11.2 世界热轧无缝钢管的现状.31.3 我国无缝钢管行业存在的问题.31.3.1 生产过剩，供大于求.41.3.2 品种结构急需调整.41.3.3 自主创新能力不强.41.3.4 管坯质量不高，有待提高.41.3.5 产品质量不高，精整尚需加强.51.3.6 提高管理水平，优化经济指标.51.4 无缝钢管生产工艺.51.4.1 无缝钢管生产工艺流程.51.4.2 其具体工艺过程如下.6第二章 移钢机设计方案选择.82.1 移钢机的简介.82.2 移钢机设计方案.82.3 选择移钢机传动方案.9第三章 移钢机的设计计算.113.1 移钢机设计参数.
