DRIVE SHAFT CONSTANT VELOCITY JOINT ASSEMBLY WITH RADIAL ELLIPTICAL PROJECTIONS

摘要

A driveshaft assembly includes a driveshaft with a pair of universal jointsdisposed at each end of the driveshaft. Each of the universal joints providestorque transferfrom the driveshaft to an adapter disposed to driveshaft using a plurality ofellipticalprojections that mate with interior grooves of the adapter. Stressconcentration on theprojections may be reduced in some embodiments by providing a variable radiusfilletaround each of the projections at the intersection of the projection with thedriveshaft.
