Abstract
A thrust cancelling shaft coupling in which two generally axially disposed flanges are connected by two frustoconically shaped elements positioned in opposite relationship to one another. The large ends of both elements are connected to the flange on one shaft and both small ends are connected to the flange on the other shaft. The thrust forces generated in one element as a result of a tendency to shorten in length under rotational and thrust forces are counteracted by the corresponding forces in the other element so that thrust forces are not transmitted from the element to either the shafts, bearings or other parts of the driving and driven equipment. The larger end of each element is connected to the respective flange, with a sleeve-like member interposed between the larger ends of the elements, and the smaller ends of the elements are connected to a cylindrical member on the opposite flange. The two torsional elements, which are identical in size and shape, are constructed of elastomeric material and are capable of absorbing substantial angular and parallel misalignment between the drive and driven shafts.
