Embodiments of this disclosure are directed to devices that allow for adjusting of device parameters in a manner that does not involve power dissipation in an essential way. Thus, power demands when such devices are used in applications can be insignificant. This applies to both springs and inerters, which constitute basic lossless building blocks of mechanical device systems, and are analogues of inductors and capacitors in electrical circuits. Embodiments of this disclosure are also directed to a lossless adjustable 2-port transformer, and realization of mechanical translational and rotary transformers are set forth in the following. Embodiments of this disclosure allow for reduction of power demands in adjusting device parameters.

A flexible friction driving device has a driving gear, a driven gear, a hexagonal sleeve, a damping ring, an elastic ring and two bearing seats, wherein the driving gear is mounted below the driven gear and engaged with the driven gear; the hexagonal sleeve is disposed between the two bearing seats, and the damping ring and the driven gear are successively sheathed on the hexagonal sleeve; a cap and the elastic ring are placed in an opening at one end of the driven gear; the elastic ring compresses the damping ring onto a cylindrical outer surface of the hexagonal sleeve; power from a motor is transferred to the driven gear by the driving gear; and, the power is flexibly transferred to the hexagonal sleeve by the friction of the inner holes of the damping ring and the driven gear against the cylindrical outer surface of the hexagonal sleeve.

In one example, a bearing or transmission has an outer race that extends circumferentially about a central axis. An inner race is disposed within the outer race and extends circumferentially about the central axis so as to be coaxial with the outer race. A plurality of load-bearing rolling elements are disposed between the inner race and the outer race, and are spaced circumferentially from one another so as to not contact one another. A plurality of separator rolling elements are disposed within the outer race. Each separator rolling element is disposed between a respective pair of the load-bearing rolling elements such that the separator rolling element is in rolling contact with the load-bearing rolling elements of the respective pair. The load-bearing and separator rolling elements form a contiguous ring.

A motor driven spindle assembly for a dispenser includes a spindle that defines an interior volume. A motor is disposed within the interior volume of the spindle and is operable to rotate the spindle. A bracket includes a plate, a first leg, and a second leg. The plate of the bracket is positioned within the interior volume of the spindle. Proximal end portions of the first and second legs are positioned at the plate. A distal end portion of the first leg is positioned within a first opening of a bushing such that the distal end portion of the first leg is slidable within the first opening along a lateral direction. A distal end portion of the second leg is positioned within a second opening of the bushing such that the distal end portion of the second leg is slidable within the second opening along the lateral direction.

Disclosed is a speed reduced driven turbocharger that utilizes a step-down roller that is coupled to a turbo shaft with a traction interface. Either a flat or a shaped traction interface can be used. The step-down roller mechanically actuates either a mechanical or hydraulic transmission, or can be mechanically coupled to an electric motor/generator.
