The paper is a theoretical analysis of a toothed coupling. It shows the inherent necessity of backlash and its optimal value; it presents a critical comparison of all the existing designs and those proposed by the author, based upon: (a) Maximum and total lag angle between the shafts as a function of misalignment; (b) maximum backlash that may appear between the teeth; (c) angles at which the teeth are in contact; (d) power losses; and (e) type of contact stresses. Finally, it presents the coupling with conical teeth against conical teeth as an optimal toothed coupling.
