摘要
斗式提升机是一种被普通采用的垂直输送设备, 用于运送各种散状和碎块物料，例如水泥，沙，土煤，粮食等，并广泛地应用于建材、电力、冶金、机械、化工、轻工、有色金属、粮食等各工业部门。斗式提升机的结构特点是：被运送物料在与牵引件连结在一起的承载构件料斗内，牵引件绕过各滚筒，形成包括运送物料的有载分支和不运送物料的无载分支的闭合环路，连续运动输送物料。驱动装置与头轮相连，使斗式提升机获得动力并驱使运转。
本次设计主要针对TD400的整体结构设计,驱动滚筒的设计,料斗的设计，斗式提升机输送能力的计算，驱动轮转速以及功率的确定，电机、减速机等主要零部件的选择及驱动轴的设计校核，包括斗式提升机总装图以及零件图，二级减速器总装图的Auto-CAD图纸的绘制。通过计算选取方案,因工作效率要求较高,故排除TD250,而选取工作效率更高的TD400斗式提升机。同样考虑到工作要求，选取深料斗，以满足工作需要。

ABSTRACT
The bucket elevator is a common vertical transportation equipment for the delivery of a variety of bulk and fragments of materials such as cement, sand, soil, coal, grain, and is widely used in building materials, electricity, metallurgy, mechanical, chemical industry, light industry, nonferrous metals, grain and other industrial sectors. Bucket E levator is the structural characteristics: the materials being transported together with t he traction of carrying components of the hopper, the traction around the drum pieces, forming a closed loop containing a branch of a delivery of materials and a branch of t he non-delivery of materials, the Movement for conveying materials. The design of th e main TD400 overall structural design, the design of the drive pulley,the design of the hopper, the calculation of bucket elevator transmission capacity,the determination of drive wheel speed and power, the select of motor, reducer, belt and other parts and the drive shaft design verification, including the bucket elevator final assembly drawing and part drawing, the Auto-CAD final assembly drawing of the secondary gear reducer. Selected by calculations, due to the high efficiency requirements, ruling out TD250, and selecting TD400 bucket elevator. Given the same job requirements, I choose deep hopper to finish my work.
KEY WORDS: Bucket elevator，drum，drives，reducer ,tensioning device，traction components
