1、 毕业设计(论文)题目：塔式起重机回转机构设计系 （部）： 电气工程系 专 业：机电一体化 班 级： 机电 0905 班 学 生： 学 号： 指导教师： 2010 年 06 月iTC6012 起重机回转机构设计摘 要塔式起重机在现代建筑中起着越来越重要的作用。作为塔式起重机的重要部分回转机构，对塔机的性能起着至关重要的作用。所以对回转机构性能的合理化设计，有利于其长周期工作。现把塔机的最大工作幅度从 55m 增加到 60m,使得塔机的结构变化小，便于通用，便于加工，便于运输。塔式起重机在现代社会中起着越来越重要的作用，普遍使用在核电站建设，水电站建设，港口码头货物的起装，发挥着重要的作用。随着
2、社会的进步，科技发展人类的居住空间越来越小，人们的房子越建越高，塔机在高层建筑建筑施工中发挥着越来越重要的作用，作为塔式起重机的重要部分回转机构，对塔机的性能起着至关重要的作用。把塔机的最大工作幅度从 55m，增加到 60m,使得塔机的结构变化小，便于通用，便于加工，便于运输。尤其是回转机构对塔机的性能的合理化设计，有利于其长周期工作。通过对塔机回转机构的风载计算，惯性载荷计算，最后转化成回转载荷，拟定回转机构的传动方案，最后，经过比较得到合理的传动方案。通过设计和计算得到了合理的传动方案，使得回转机构满足塔机的长期使用，并且使塔机的上半部分相对塔身坐 360的自由旋转，以便完成各种起重作业要
3、求。在设计中使用到了液力耦合器，并根据要求设计了行星齿轮减速器，最后设计了合理的回转机构。关键词：塔式起重机；回转机构；行星齿轮减速器 iiTC6012 Rotary Tower Crane DesignAbstractTower crane is playing an increasingly important role in modern architecture.
