ABSTRACT:
A slap yoke, for connection to a non-cylindrical shaft in a rotary-drive device, has an axially extending non-cylindrical socket for radially receiving the non-cylindrical shaft, the socket having two laterally opposed holes in its walls for transverse installation of a clamp bolt. A threaded clamp bolt having a drive head for bearing against the outer surface of one wall of the non-cylindrical socket extends through the opposed holes and carries a cylindrical jacket fitted over the bolt. The jacket has longitudinally centered features for causing radial expansion of the jacket under an axial compressive load. The yoke has a threaded member at one of the opposed holes for receiving the clamp bolt and for causing a compressive axial load on the cylindrical jacket when the clamp bolt is threaded thereinto.
