DESIGN AND ANALYSIS OF GEOMETRICAL PARAMETERS INFLUENCING ON CURVIC COUPLING

It has widely observed that boltsturn loose, when subjectedto fluctuating loads. This ultimately reduces the forceof bolt and leads to fail in the performance. Such failures can cause sudden great damagein safety critical applications. Therefore, it is necessary to design couplings withhigh positioning accuracyand high indexing stiffness. So the concept of curvic coupling was come in to existence.The stresses induced in the coupling have been analyzed by analytical method. A three dimensional finite element model of curvic coupling is developed in finite element software to compare to analytical results. The modelconsists of coupling assembly. A moment is applied on coupling & simulates the effects.Based on these results, a finite element analysis should be used if a greater level of detail is required for the analysis of curvic coupling
