ABSTRACT:
An apparatus (10) comprising an outer tubular member (30) having an axis (32). An inner member (90) extends into the outer tubular member (30, 90) and is coaxial with the outer tubular member. The members (30) have surfaces (52a, 102a, 102b) which define a plurality of races (112) spaced circumferentially around one of the members (90). At least one rotatable element (140) is in each of the races (112). The rotatable elements (140) engage the outer tubular member (30) and the inner member (90) and guide relative axial movement of the outer tubular member and the inner member and transmit torque between the outer tubular member and the inner member. One of the members (30) applies radially directed force to the rotatable elements (140) urging the rotatable elements radially into contact with the other member (90) to provide for a no-lash torque transmission between the members. In a preferred embodiment, the one member (30) applies the radially directed force through an elastically deformed portion provided by a plurality of aligned slits (88).
