中文摘要麦芽除根机器是一种制麦生产工艺过程中一道很主要工序的专用机器，除根机的设备主要是由除根装置、风门、抽风装置、机架、传动系统、打散装置等部件组成。麦芽根中含有有害杂质而且苦，影响啤酒的道和色泽，需要将其除去，用传统方法除根，易去根不完全而且会损伤麦芽的缺陷，与传统方法相比，本机在除根的同时不会破坏麦芽，其型号特有的螺旋刀片不仅可以彻底除根，而且还有轴向推动作用，提高了生产率。这次任务主要围绕麦芽除根机的结构及传动系统开展了分析设计，对麦芽除根机的总体方案、带传动和链传动、主轴等部件进行了设计，整个传动系统主要是利用带轮、链轮以及轴来传递运动和动力，所以对带传动的相关参数要求进行了设计计算并对轴的结构强度进行设计和校核。由于时间和资料有限，没有进行参数化设计，只对除根机的三种不同型号进行了建模，列出了不同型号除根机的参数选择。50275

Abstract   Malt root machine is a very major operation in the malt production process of special machines, the root device is largely determined by the root device, throttle, exhaust, frame, transmission system, scattered into device components. Malt root in the contains victims impurities and flavor bitter, effect beer of taste and color, needs will its dropped, with traditional method root, has to root not full and will injury malt of defects, and traditional method compared to, this machine in root of while not damage malt, its model unique of spiral blade not only can thoroughly root, and also has axis to promote role, improve has productivity. 　　　This task main around malt root machine of structure and the drive system carried out has analysis design, on malt root machine of overall programme, and with drive and chain drive, and spindle, parts for has design, whole drive system main is using with round, and sprocket and axis to passed movement and power, so on with drive of related parameter requirements for has design calculation and on axis of structure strength for design and check. Due to limited time and information, lack of parametric design, only the root has three different types of modeling, lists the different models of root parameter selection.
