ABSTRACT:
A locking rotation-transmitting coupling comprises a nonrotatable member providing a housing having a cylindrical bore surface; a driven member having a hub portion that is, in cross-section, a regular polygon concentric to the bore axis, with axially extending sides that oppose and are radially spaced from the bore surface; and a driving member having axially extending fingers in the space between the bore surface and the hub portion, there being as many fingers as there are sides of the polygon, and the fingers being equidistant from said axis and spaced at uniform circumferential intervals. Two identical roller elements are confined in each space between circumferentially adjacent fingers. Every roller element is in contact with both the bore surface and one of the side surfaces on the hub portion, for preventing rotation of the driven member when no torque is applied to the driving member, and is also in contact with one of said fingers and the other roller element of its pair for transferring torque from the driving member to the driven member.
