abstract

A study has been conducted on the design of a conical coupling joint in which torque is transmitted by frictional contact across conical surfaces on the flanges. Three dimensional finite element analyses were undertaken on the coupling, employing a full 360-degree model along with more detailed analytical studies using a representative cyclic symmetry model. Parametric studies were done on a number of geometries where investigations were made with the aim of improving the pressure distributions and values in the contact region, while working towards maximizing the torque capacity on the joint. The results showed that the torque capacity is strongly dependent on the angle of the conical surface. A 0.5° angular variation between two contacting conical surfaces provided an increase in contact area and a significant reduction in the contact pressure peaks. As part of the study on the design improvement, the potential effects of manufacturing variations were investigated and results showed that variations of ±0.25° should not significantly affect the assembly accuracy. A parallel experimental study of a prototype joint was also undertaken. Measured torque capacity on the prototype was in good agreement with values predicted by the finite element models.
