Abstract
Abstract THIS COUPLING FOR PARALLEL SHAFTS COMPRISES TWO COUPLING MEMBERS RIGID WITH SAID SHAFTS AND INTERMEDIATE MEANS FOR CONNECTING THEM. STRAIGHT RADIAL GUIDEWAYS ARE PROVIDED EITHER ON THE COUPLING MEMBERS OR ON THE INTERMEDIATE MEANS. A SINGLE INTERMEDIATE PART WORKING THROUGH SAID GUIDEWAYS CAUSES DYNAMIC UNBALANCE. THE INVENTION PROVIDES TWO INTERMEDIATE PARTS MOVABLE AT RIGHT ANGLES TO EACH OTHER ON EACH COUPLING MEMBER, ACHIEVING MASSBALANCE AND INCREASED LOAD CAPACITY. FRICTION IS MINIMIZED WITH CYLINDRICAL ROLLERS ADAPTED TO CONTACT BOTH SIDES OF THE GUIDEWAYS ENGAGED THEREBY.
