Abstract:
1. A speed/torque enhancing power transmission comprising: a) a housing structure; b) a ring gear member journalled on the housing structure for rotation about an axis and adapted for external connection thereto for power transmission; c) a shafting structure journalled on the housing for rotation about said axis, said shafting extending axially in opposite directions from the ring gear member along said axis and having a first eccentric surface thereon and a second eccentric surface diametrally opposed to and axially adjacent said first eccentric surface; d) a first spur gear member disposed for rotatably contacting said first eccentric surface, and disposed on said housing structure for non-rotatable orbital movement about said axis for orbitally engaging the ring gear; e) a second spur gear member disposed for rotatably contacting said second eccentric surface and disposed on said housing structure for non-rotatable orbital movement about said axis for orbitally engaging the ring gear; and, f) wherein upon power input to one of the ring gear and the shafting, the speed of the other is respectively increased and decreased; and, further comprising: g) a first plate member with a first set of surfaces disposed on opposite sides of said axis and contacting said first spur gear for sliding movement in a first direction normal to said axis of rotation, with a second set of surfaces on opposite sides of said axis contacting said first spur gear for sliding movement in a second direction normal to said axis of rotation and orthogonal to said first direction; and h) a second annular plate member with a first set of surfaces disposed on opposite sides of said axis and contacting said second spur gear for sliding movement in a first direction normal to said axis, with a second set of surfaces on opposite sides of said axis contacting said second spur gear for sliding movement in a second direction normal to said axis and orthogonal to said first direction.
