高速大功率万向联轴器应用研究

Application Research on High-speed Big-power Universal Coupling

采用有限元分析方法对万向联轴器十字轴进行了强度分析计算,根据结果对十字轴的相应部位进行了改进设计;针对高速大功率万向联轴器高转速、长寿命的使用条件和要求,在不增加尺寸和重量的前提下,对十字轴承副进行了优化设计。样机试验证明:高速大功率万向联轴器的承载能力和使用寿命大大提高。

Strength analysis and calculation was carried out on the spider of universal coupling using FEA method.According to the analysis results,some part of the spider was modified and improved.Considering that high-speed big-power universal coupling works under high speed condition and has to have long life,the spider was optimized without increasing of dimensions and weight.Prototype test showed that the coupling＇s bearing capacity and service life had been significantly enhanced.
