摘 要
小型载货电梯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，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。
本次设计主要针对小型载货电梯电动机的设计，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，包括总装图以及零件图，二级减速器总装图的Auto-CAD图纸的绘制。通过计算选取方案，以满足工作需要。
电梯源于简单的绳索或手拉葫芦。电梯基本上是通过机械手段拉或推起的平台。一台现代化的电梯包括轿厢安装在竖井的围住的空间的平台上，或在英联邦国家称为“吊重机” 。在过去，电梯驱动机制，采用蒸汽和水的液压活塞。在一个“牵引”电梯，车被深处的带沟槽的滑轮通过滚动的钢丝绳拉起，通常称为滑动轮。车子的重量是用其他的重物来平衡。有时两个电梯总是同步移动方向相反，他们是彼此的制衡。
电梯使用的原则，液压加压地上或地下的活塞，以提高和降低轿厢。拉拢液压使用两者相结合的绳索和液压动力，以提高和降低轿厢。最近的创新包括永久地磁极马达，机房无轨道式齿轮机，微机控制：该技术是用在新装备上取决于多种因素。液压电梯便宜，但安装气瓶大于一定长度变得不切实际的在非常高的升降机盘中。许多建筑物超过7层时，牵引电梯必须被取代使用。液压电梯通常比牵引电梯慢。

Selected by calculations,?to finish my work
Elevators began as simple rope or chain hoists. An elevator is essentially a platform that is either pulled or pushed up by a mechanical means. A modern day elevator consists of a cab (also called a "cage" or "car") mounted on a platform within an enclosed space called a shaft, or in Commonwealth countries called a "hoistway". In the past, elevator drive mechanisms were powered by steam and water hydraulic pistons. In a "traction" elevator, cars are pulled up by means of rolling steel ropes over a deeply grooved pulley, commonly called a sheave in the industry. The weight of the car is balanced with a counterweight. Sometimes two elevators always move synchronously in opposite directions, and they are each other's counterweight.
The friction between the ropes and the pulley furnishes the traction which gives this type of elevator its name.
Hydraulic elevators use the principles of hydraulics to pressurize an above ground or in-ground piston to raise and lower the car. Roped Hydraulics use a combination of both ropes and hydraulic power to raise and lower cars. Recent innovations include permanent earth magnet motors, machine room-less rail mounted gearless machines, and microprocessor controls
