【正文】 stract Tower crane is playing an increasingly important role in modern architecture. As a vital ponent of the tower crane—slewing mechanism, which is quite essential to the rationalization of the tower crane. The design of slewing mechanism is good to its longperiod of work. The increase of the maximum working range of the tower crane from 55m to 60m, enables its structure to change less, which is easy to ventilate, process and transport. Tower crane in modern society are playing an increasingly important role in widespread use in nuclear power plant construction, construction of hydropower stations, port cargo loaded from playing an important role. Along with social progress, scientific and technological development of human living space smaller and smaller, the more people build houses higher, tower crane in highrise building construction in the building playing an increasingly important role as an important part of the tower crane slewing mechanism, the performance of the tower plays a vital role. Particularly slewing tower crane performance on the rationalization of design, beneficial to its long cycle of calculating the wind load and inertial load of the tower crane39。的自由旋轉(zhuǎn)，以便完成各種起重作業(yè)要求。 通過對塔機回轉(zhuǎn)機構的 風載計算，慣性載荷計算，最后轉(zhuǎn)化成回轉(zhuǎn)載荷，擬定回轉(zhuǎn)機構的傳動方案，最后，經(jīng)過比較得到合理的傳動方案。把塔機的最大工作幅度從 55m，增加到 60m,使得塔機的結構變化小，便于通用，便于加工，便于運輸。 塔式起重機在現(xiàn)代社會中起著越來越重要的作用，普遍使用在核電站建設，水電站建設，港口碼頭 貨物的起裝，發(fā)揮著重要的作用。所以對回轉(zhuǎn)機構性能的合理化設計，有利于其長周期工作。 西安工業(yè)大學北方信息工程學院 本科畢業(yè)設計 (論文 ) 題目 ： TC6012塔式起重機 回轉(zhuǎn)機構 設計 系 （ 部 ）： 機電信息 系 專 業(yè)： 機械設計制造及其自動化 班 級： 學 生： 學 號： 指導教師： 2021 年 06 月 i TC6012 起重機回轉(zhuǎn)機構設計 摘 要 塔式起重機在現(xiàn)代建筑中起著越來越重要的作用。作為塔式起重機的重要部分—— 回轉(zhuǎn)機構，對塔機的性能起著至關重要的作用。現(xiàn)把塔機的最大工作幅度從 55m增加到 60m,使得塔機的結構變化小，便于通用，便于加工，便于運輸。隨著社會的進步，科技發(fā)展人類的居住空間越來越小，人們的房子越建越高，塔機在高層建筑 建筑施工中 發(fā)揮著越來越 重要 的 作用， 作為塔式起重機的重要部分 —— 回轉(zhuǎn)機構，對塔機的性能起著至關重要的作用。尤其是回轉(zhuǎn)機構對塔機的性能的合理化設計，有利于其長周期工作。 通過設計和計算 得到了合理的傳動方案，使得回轉(zhuǎn)機構滿足塔機的長期使用，并且使塔機的上半部分相對塔身坐 360176。在設計中使用到了液力耦合器，并根據(jù)要求設計了行星齒輪減速器，最后 設計了合理的回轉(zhuǎn)機構。s slewing mechanism and last rotary load which are turned into, transmission schemes are worked out, and then the reasonable transmission plan are obtained after parison at the end. Reasonable transmission schemes that are gotten from calculation makes slewing mechanism meet the tower crane39。 freely relative to its body in order to finish various demands of the lifting operation. In the meantime, use hydraulic coupler and design the plaary gear reducer reasonable rotation schemes are designed.
