电动起重葫芦设计 摘要 起重机械在近年来现实应用很大。起重机械设计的安全和实际操作实用性有重要意义。起重机械设计从始至终都存在着很大困扰。近代全世界都在致力于对于起重机械设计周期进行缩短的问题，还有对加速起重机设计方法加速的趋势。在满足机体本身的要求之外，需要对起重机械的设计周期的加速进行改进，还有机体本身体重也要进行改进，经济效率需要进行大幅度的提高，这些对于实际应用有着很大的意义 电动葫芦就是起重机械的一份子。电动起重葫芦是目前体积最小的机械。设计本身就是财产与生命的安全必须放在首位，其次是故障的检修。电动起重葫芦是由滚筒装置、挂钩装置、操作机构、联轴器、减速机、电机等组成。设计的是1.6t单钩钢丝绳电动起重葫芦还有传动系统。在参照了许多资料后，进行了合理构思。对减速器和电机E形设计、钢丝绳选择和强度校核进行了校核，并对其体积进行了校核。对气缸参数、齿轮传动比、各齿轮参数、强度计算、轴、轴承等各种机械零件的选择进行了计算校核计算，并对齿轮、轴、RO的装配图进行了选择。绘制了LLER、减速箱和升降机构。 关键词：电动葫芦；卷筒装置；起重机械；吊钩；减速器；装配方案； Abstract Lifti
