This paper proposes the concrete design, in view of the cooling system of Mandrill. According to the requirements and the fundamental principle of cooling system, the paper chose the first as a selection of the design, by a detailed analysis and comparison of working principle ,as well as advantages and disadvantages of the three proposals. Through consultancy to relevant materials, analysis and calculation the paper determines the model of motors, reducers, shaft, coupling, keys, and other important parts,and checks up the important parts. On this basis, then design the structure of other non-standard components, such as, rotating on the feeder, move steel and other important components etc. According to the above method, the task of cooling mandrel rotation can be complete well【17】. Key words: mandrill ; cooling ; steel pipe ; proposal. 目 录 1.3 限动芯棒连轧机的发展与国内的应用 4 1.3.1 MPM的推广史 5 1.3.2 MINI-MPM的应用史 6 1.4芯棒连轧管机的应用与发展 7 1.4.1 芯棒的简介与生产情况 8 1.4.2 芯棒的工作概述 8 二 方案分析与确定 10 2.1 方案一的结构设计 10 2.1.1 工作原理 10 2.1.2 旋转冷却装置的设计 11 2.2 方案二的结构设计 12 2.4 方案的比较与选择 13 三 电动机的选择确定 14 3.1 设计任务书的参数 14 3.2 选择电动机类型和结构形式 14 3.3 工作机功率的计算 15 3.3.1 工件的重力计算 15 3.3.2 工作的受力分析 16 3.3.3 圆周速度的确定 16 3.4 电动机容量的计算与确定 17 3.4.1 电动机容量计算 17 3.4.2 电动机的选择 18 四 减速器的选择 20 4.1 减速器的分类 20 4.2 减速器的选择与计算 20 4.2.1 减速器传动比的初步确定 21 4.2.2 减速器承载能力的计算 21 4.2.3 减速器的选择 21 五 轴的设计计算与校核 23 5.1 轴段长度和直径的确定 23 5.1.1 轴的最小直径的确定 23 5.1.2 轴的直径和长度的确定 24 5.2 轴的校核 26 5.2.1 轴的力学模型的建立 26 5.2.2 绘制力学模型 26 5.2.3 按弯扭矩合成校核轴的强度计算 27 六 联
