a型吊籃提升機結(jié)構(gòu)設計

畢業(yè)設計（論文）中文摘要

     此設計為a型吊籃提升機的結(jié)構(gòu)設計。提升機的端部為帶有盤式制動器的三相異步電機，經(jīng)減速機構(gòu)驅(qū)動滾輪。在滾輪與壓盤結(jié)合面的外徑上，設有繩槽。在鋼絲繩進出口處繩槽縫隙大于鋼絲繩直徑，在進出口對面區(qū)域則小于鋼絲繩直徑，鋼絲繩被繩槽夾緊。通過滾輪的旋轉(zhuǎn)，使鋼絲繩導入或?qū)С觥?br />      選擇合理可靠的傳動方案是保證機構(gòu)可靠性的前提，故設計中在不違背設計手冊的前提下盡量采用較大的安全系數(shù)。設計合理的整體結(jié)構(gòu)，從而提供有效的設備維修和更換易損件手段，縮短維修時間，也是提升機設計的一個重要內(nèi)容。為提高機構(gòu)的傳動精度及承載能力，一級減速為蝸輪蝸桿傳動，二級減速為齒輪傳動。

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
