桥式起重机三支点起升机构减速器受力分析

摘要

According to the features and structure of QDL series of light-weight general hoisting mechanism of the bridge crane,the paper conducts stress analysis on its single support reducer,core parts of the hoisting mechanism.Bearing reaction force of the new reducer is calculated in the paper as well as load on its output shaft and bearing,providing reference for designing new reducers.%依据QDL系列轻量化通用型桥式起重机起升机构的特点及结构形式,对其核心部件单边支撑形式减速器进行了受力分析,计算了新型减速器的支反力,对减速器的输出轴及轴承进行了载荷分析计算,为该新型减速器的设计提供了参考.
