    Abstract: A hypotrochoid positive-displacement machine includes an inner rotor and an outer rotor with intermeshing projections. During rotation of the rotors, the inward-most tips of the outer rotor trace hypotrochoid paths relative to the inner rotor. A driven rotor, for example the inner rotor, drives a driven rotor, for example the outer rotor, by contact between driving surfaces and driven surfaces of the respective rotors. Improvements are provided, for example in relation to the contact between the rotors. In use of the device contact between the driving surfaces and driven surfaces may move radially outward from a point of initial contact. The driving or driven surfaces or both may be arranged to flex under contact between the rotors. The driving surfaces may be convex. The driven surfaces may be concave.

    Abstract: A high speed ratio drive system is formed of planet rollers, each having varying diameter, an outer fixed ring in contact with one diameter of the planet rollers, and an outer drive ring in contact with another diameter of the planet rollers. An inner drive element is provided by a sun drive roller in contact with the planet rollers or by a planet carrier. Preferably the system has an axial reflective symmetry minimizing twisting forces on the planet rollers.

    Abstract: A speed reducer drive can drive an output relative to a fixed ring using planet rollers having different diameter in contact with the output and fixed ring. Elements of the device can be formed of axially arranged segments for ease of construction. Backlash may be removed by manipulation of the drive before tightening segments of the rollers to fix the segments together by friction. The rolling contacts between elements can include a mix of geared contacts for better torque and ungeared contacts to act as bearing surfaces. Geared or ungeared surfaces may be tapered. Elements may be axially adjustable relative to each other, allowing backlash to be removed in combination with taper.

    Abstract: A planetary gearbox with two rows of planets, at least some of the planets including magnets. The planets are driven by a stator to drive the gearbox as a motor. The planets may be geared with axial portions with different helix angle to position the gears and avoid the need for a planet carrier or bearings. Gears with small heights and/or high pressure angles may be used to avoiding or reduce negative effects of conventional gearing.

    Abstract: A power conversion device has a buckled wave disk that has an axis and is radially compressed between a hub and a wave ring. The buckled wave disk is buckled in the radial direction to form circumferential waves which are displaced in the axial direction and extending around the buckled wave disk with lines formed of inflection points of the circumferential waves extending between the hub and wave ring. The wave ring is outwardly radially displaced at nodes corresponding to lines formed of inflection points of the circumferential waves. A wave propagation actuator cooperates with the buckled wave disk for driving a wave and the lines formed of inflection points of the circumferential waves around the buckled wave disk. An outer ring surrounds the wave ring, the outer ring being driven by or driving the wave ring at the nodes. A method of making a wave disk is provided.

    Abstract: A two dimensional structure such as a disk or belt is shaped or distorted to form a buckling wave. At least one contact touches the wave, two contacts squeezing the wave between them providing a firmer connection. The wave is propagated along the structure by any of a variety of means including magnets or piezo actuators. This movement of the wave moves the contacts relative to the two dimensional structure, providing a high leverage ratio.

    Abstract: A motion producing device comprising an output member with a contact surface and a reference member. An actuator member is attached to the reference member, the actuator member having a traction surface and comprising actuator zones, each actuator zone being energizable to move a corresponding portion of the traction surface to change a contact state of the traction surface with the contact surface depending on an energized state of the actuator zone. An energy source isoperatively coupled to the actuator zones for sequentially changing the energized state of the actuator zones. The actuator member provides a torque transmission path between the reference member and the output member.
