【摘要】 滚珠联轴器是一种新型高效的联轴器，本文应用有限元分析的方法对滚珠联轴器的失效机理和承载能力进行了分析和计算，是比较先进的。 首先，对滚珠联轴器进行了结构设计，提出了两种结构设计方案。 其次，根据非线性接触理论，对滚珠联轴器在受扭矩载荷作用下的接触应力进行了分析和计算。在施加静载时，找出滚珠联轴器产生接触应力最大值的区域，并计算在不同结构参数下的应力值，分析滚珠联轴器的结构参数对应力值的影响情况，获得了应力值变化规律曲线。 然后，比较两种方案在相同载荷，相同结构参数下所受应力值的差异，得出了两种方案的优缺点，指出了它们的不同的应用场合。 最后，提出了滚珠联轴器设计方法，分析出了其最优的结构参数，为实际应用以及今后进一步分析打下了良好的基础。更多还原

【Abstract】 The steel-ball coupling is a kind of new and highly-efficient drive part. This paper analyzes the mechanism of the rolling-ball coupling being destroyed and calculates its load capability by using the finite element method, which is quite advanced.First, the coupling’s model is completed, and the two projects about this model are put forward.Second, the coupling’s contact stress values are analyzed and calculated when put on the torque, according to the non-linear contact theory .The largest contact stress values have been found out by the static load. The rule curves about changing stress values are obtained through the method of analyzing and calculating the stress values on different model parameters.Third, both the disadvantages and the advantages about two projects, and where the two kinds of couplings could be used are obtained by comparing their stress in the same conditions (the loads are same, and their structure parameters are same).Forth, the methods of designing the coupling’s structure are put forward, and the best coupling’s structure parameters are also acquired. So this paper has laid a good foundation for the coupling’s application and the further analysis.更多还原
