| 摘要：异步轧制是上下工作辊表面线速度不等，以降低轧制力；因此又称差速轧制，也称搓轧。设计部分主要包括：异步轧机的两条主传动系统传动链的设计，包括电动机的选择设计，联轴器的选择设计，减速器的选择设计，万向联接轴的选择设计和测试系统的设计等。设计过程按照国家标准和机械设计标准来设计的。两条主传动系统和测试系统是设计的重点，其各自的布局与传动方式和结构类型对主机系列性能的优劣以及工艺效果起着重要的作用。设计中参照了相关文献资料进行了机构的优化设计，并对主要部件进行了强度校核。同样万向接轴和测试系统及传感器的选择设计，也是设计的重要环节。异步小型轧钢机结构简单、操作方便、适用工艺范围大，使用性能好，可保证加工产品的性能良好，板型好，能够达到设计要求。5279 关键词：异步轧机；测试系统；万向联接轴；传感器 Design of Main Drive and Test System of Small Composite Test Mill Abstract:The design of the chain plate rolling machines by drawing on its revolving roller contacts the role of friction will be rolling the metal body (work piece) dragged into the roll gap between the roll under pressure, mainly in the work piece thickness. Completion of the direction of plastic molding.The design of the design includes: asynchronous rolling mill of the two transmission chain design, including the choice and design of the motor, coupling and reducer,the design of the system and the universal connection of the axis of selection and test system design, etc. The design process in accordance with the National Institute of Standards and mechanical design criteria for design. Gear reduction system is the focus of this design, the design of the mechanical design reference manual for the precise design, and check the strength.The universal pick axis and the choice of the sensor in the test system are also the design key point.The design of the chain plate rolling machine structure is simple and inexpensive to use and in line with the design requirements, mainly for the processing chain for the volume of the material plate designed. Can be processed to ensure good product performance, high surface finish, plate type, and to meet the requirements. keywords: Asynchronous rolling mill; Test system; Universal connection axis; Sensor 目录 1 绪论1 1.1 引言1 1.2 项目背景1 2 设计方案的确定3 2.1 课题中的主要重点及解决方案3 2.2 主传动系统拟定的一般原则 3 2.3 确定最终传动方案4 3 定速传动链的设计6 3.1 电动机的选择与设计6 3.1.1 选择电动机的类型7 3.1.2电动机功率的选择与计算7 3.1.3选择电动机的型号8 3.2 联轴器的选择8 3.3 键联接的选择及校核 9 3.3.1 键类型的选择9 3.3.2 键类型的校核9 3.4减速器的选择10 3.4.1 选择减速器齿轮的类型10 3.4.2 选择减速器齿轮的级数11 3.4.3 确定减速器的型号11 3.5 传动轴的选择11 3.5.1 滑块式万向联接轴11 3.5.2 滑块式万向接头的受力分析和强度计算12 4 调速传动链的设计15 4.1 电动机的选择与设计15 4.1.1 选择电动机的类型15 4.1.2 电动机功率的选择与计算16 4.1.3 选择电动机的型号17 4.2 联轴器的选择17 4.3 键联接选择及校核18 4.3.1 键类型的选择18 4.3.2 键类型的校核18 4.4减速器的选择19 4.4.1 选择减速器齿轮的类型19 4.4.2 选择减速器齿轮的级数20 4.4.3 确定减速器型号20 4.5 传动轴的选择20 4.5.1 滑块式万向联接轴20 4.5.2 滑块式万向接头的受力分析和强度计算21 5 测试系统的设计24 5.1 测试的概述24 (责任编辑：qin) |
