摘要 .洛阳理工学院毕业设计（论文） PAGE IV . PAGE I TRM辊磨机整机结构和分离器设计 摘 要 辊磨机又称立磨，是利用料床粉碎原理进行粉磨物料的一种研磨机械。它主要用于水泥、煤炭、电力等行业。选粉机是与大型辊磨机相配套的粉末分选设备，到目前为止，国内在选粉机的设计上尚无完善的理论，现存的选粉机性能不高，因此尽早开发出高性能的选粉机将加快大型辊磨机的国产化进程，同时将提高企业的市场竞争力。 本次设计是在完成辊磨机整体结构设计的基础上，将重点放在选粉机的结构设计和校核，使之与日产5000吨的水泥工艺相适应。 设计分为以下几个板块：壳体部分的设计，壳体尺寸根据工厂现场测绘获得，进料口在壳体右侧与壳体配合；回转部分的设计，根据轴承与主轴的配合确定主轴分段，主轴下面连接笼型转子；传动部分的设计，根据功率选择电动机，通过主轴转速和电动机转速选取合适的减速器；润滑系统的设计，设置稀油站供油润滑，轴承充油脂。 本次设计是根据设计任务书所提供的台时产量进行的辊磨机选型计算，以及完成选粉机的优化设计，使整台磨机能正常的完成粉磨作业。同时完成相关的基础设计任务。 关键词：辊磨机，选粉机，基础设计，传动装置，立轴 TRM grinding machine structure and the separator design ABSTRACT Roller mill named vertical mill, it is the use of the bed material crushing principle for grinding a grinding machine. It is mainly used in cement, coal, electric power and other industries. Powder selecting machine is matched with large vertical mill powder sorting equipment, so far, the classifier design is not perfect theory, the existing separator performance is not high, therefore the early development of high-performance powder selecting machine will accelerate the localization process of large vertical mill, at the same time it will increase the market competition ability of the enterprise. This topic is in the completed roll mill overall structure design, emphasis is placed on the powder selecting machine structural design and verification, and make the Nissan5000 tons of cement process to adapt. This Design is divided into the following sections: shell part design, housing size according to the factory scene mapping, the feed inlet is arranged on the right side of the casing cooperates with the housing; rotary part of the design, according to the bearing and spindle spindle spindle with determining section, connected below the cage rotor; the transmission part of the design, according to the power selection of motor, through the the rotational speed of the spindle and motor speed to select the appropriate reducer; lubrication system design, setting the thin oil lubrication, bearing grea
