FIELD: mechanical engineering. SUBSTANCE: coupling has shaft 1. Hub 2 is set on the shaft with a ring space. The ring space is provided with split bushing 3 having conical sections, which are directed toward each other, and cylindrical bushing 4 whose both ends are provided with threaded parts on outer surface. Conical rings 5,6 are screwed on the threaded parts of the cylindrical bushing. The rings interact with the conical parts of split bushing 3 by their outer surface. The conical rings are fixed with lock nuts 7,8. The inner surface of cylindric bushing 4 is provided with splined projections which form a splined joint with slot grooves made on the face of shaft 1. An antifriction material is applied on the threaded parts of the cylindrical bushing and on its inner surface. EFFECT: enhanced reliability. 2 cl, 1 dwg
