Abstract (en)
[origin: WO8103366A1] A nutating traction drive in which external rolling surfaces on a one-piece bi-conical body (10) are retained against axially spaced internal ring surfaces (51, 52) at diameterically opposite points of contact by a mechanism acting between a body (18) which is rotatable on the axis of the ring surfaces or a first axis (24) and which carries the biconical body (10) on a second axis (30) inclined with respect to and intersecting the first axis at a point (S) of axes intersection located midway between the ring surfaces (51, 52) and points of contact. The mechanism includes a pivotal member (66) having a fulcrum point (78) eccentric from the first axis (24) or displaced from a plane containing both the first (24) and second (30) axes so that a torque reaction to rotation of the carrying body (18) by the biconical body (10) results in a force attempting to increase the angle between the first (24) and second (30) axes. A preloading device (82) acting to rock the pivot member (66) in one direction provides a preload bias of the rolling surfaces against each other whereas an unloading device (84) operating to swing the pivot member in the opposite direction results in a removal of normal friction force between the engaged rolling surfaces.
