a型吊篮提升机结构设计

毕业设计（论文）中文摘要

     此设计为a型吊篮提升机的结构设计。提升机的端部为带有盘式制动器的三相异步电机，经减速机构驱动滚轮。在滚轮与压盘结合面的外径上，设有绳槽。在钢丝绳进出口处绳槽缝隙大于钢丝绳直径，在进出口对面区域则小于钢丝绳直径，钢丝绳被绳槽夹紧。通过滚轮的旋转，使钢丝绳导入或导出。
     选择合理可靠的传动方案是保证机构可靠性的前提，故设计中在不违背设计手册的前提下尽量采用较大的安全系数。设计合理的整体结构，从而提供有效的设备维修和更换易损件手段，缩短维修时间，也是提升机设计的一个重要内容。为提高机构的传动精度及承载能力，一级减速为蜗轮蜗杆传动，二级减速为齿轮传动。

Title       Structural Design　of  Gondola Hoist    

Abstract
This is a structural design of tape-a Gondola Hoist. The end of the Hoist is the Three-phase Induction Motor with a disc brake, and the motor drives roller with retard mechanism. There's an rope groove on outer diameter of the binding surface of roller and pressure plate. The rope groove gap in import and export of wire rope is larger than the rope's diameter, in the import and export opposite the rope groove gap is smaller than the rope's diameter, wire rope was clamping by rope groove. When the roller revolving, the wire rope import or export.
Choice of reasonable and reliable transmission of the program is the premise to guarantee the reliability of institutions, so the design is used safety factor as larger as possible under the premise of not violating the design manual. Design an rational overall structure，thus providing an effective equipment maintenance and replacement of consumable means to shorten the repair time，is also an important part of the design. To improve the accuracy and transmission capacity, the first slowdown is the worm transmission and the second is the gear transmission.

Keywords  Gondola Hoist、Speed Reducer、Worm transmission
