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(jī)回轉(zhuǎn)機(jī)構(gòu)的風(fēng)載計(jì)算，慣性載荷計(jì)算，最后轉(zhuǎn)化成回轉(zhuǎn)載荷，擬定回轉(zhuǎn)機(jī)構(gòu)的傳動(dòng)方案，最后，經(jīng)過比較得到合理的傳動(dòng)方案。把塔機(jī)的最大工作幅度從 55m，增加到 60m,使得塔機(jī)的結(jié)構(gòu)變化小，便于通用，便于加工，便于運(yùn)輸。塔式起重機(jī)在現(xiàn)代社會(huì)中起著越來越重要的作用，普遍使用在核電站建設(shè)，水電站建設(shè)，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(jī)構(gòu)性能的合理化設(shè)計(jì)，有利于其長周期工作。畢業(yè)設(shè)計(jì)(論文)TC6012 起重機(jī)回轉(zhuǎn)機(jī)構(gòu)設(shè)計(jì)摘 要塔式起重機(jī)在現(xiàn)代建筑中起著越來越重要的作用。作為塔式起重機(jī)的重要部分——回轉(zhuǎn)機(jī)構(gòu)，對塔機(jī)的性能起著至關(guān)重要的作用?，F(xiàn)把塔機(jī)的最大工作幅度從 55m 增加到 60m,使得塔機(jī)的結(jié)構(gòu)變化小，便于通用，便于加工，便于運(yùn)輸。隨著社會(huì)的進(jìn)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(jī)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(jī)的重要部分——回轉(zhuǎn)機(jī)構(gòu)，對塔機(jī)的性能起著至關(guān)重要的作用。尤其是回轉(zhuǎn)機(jī)構(gòu)對塔機(jī)的性能的合理化設(shè)計(jì)，有利于其長周期工作。通過設(shè)計(jì)和計(jì)算得到了合理的傳動(dòng)方案，使得回轉(zhuǎn)機(jī)構(gòu)滿足塔機(jī)的長期使用，并且使塔機(jī)的上半部分相對塔身坐 360176。在設(shè)計(jì)中使用到了液力耦合器，并根據(jù)要求設(shè)計(jì)了行星齒輪減速器，最后設(shè)計(jì)了合理的回轉(zhuǎn)機(jī)構(gòu)。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.
