: There is a family of spirals that can be employed in splines with various numbers of lobes that uniformly distributes the stresses in the shaft and disc resulting from torque transmission. If you have EDM capability, it's not difficult to cut this shape. An ellipse with moderately high eccentricity is a reasonable approximation of a 2 lobe implementation of this approach.

: Dodd

Would you care to elaborate on the spirals? A name or better yet an equation would be helpful. I've been playing with involutes lately for gears, is this what you mean?
