Abstract: Flywheel system properties are enhanced with rim designs that control stress at operational rotational velocities. The tensile strength of fiber-resin composites can be aligned with radial forces to improve radial stress loading. Loops with composite casings can be arranged around the flywheel circumference with a majority of the fibers being aligned in the radial direction. The loops can enclose masses that contribute to energy storage in the flywheel system. Masses can be arranged around the hub circumference with a hoop wound composite casing enclosing the masses and hub. The masses subjected to radial forces are radially displaced with increasing rotational velocity and can provide compressive force to the fiber-resin composite to contribute to maintaining composite integrity. With the alignment of fibers in hoop or radial directions, higher loading permits increase rotational velocities, which can significantly add to the amount of energy stored or produced with the flywheel.

Abstract: A pneumatic liquid on-line automatic balancer of a rotor includes: a sealed balancing disk rotating with a balanced rotor and a pressure transfer device mated with the sealed balancing disk. At least two pairs of centrosymmetric chambers filled with appropriate balancing liquid are evenly distributed in the sealed balancing disk. The pressure transfer device controls compressed gas in and out of the chamber and makes the balancing liquid controllably flow in each pair of chambers to achieve dynamic balance of the rotor. A communicating channel of the balancing liquid is provided between each pair of the chambers. The communicating channel of the balancing liquid is one and a center of the communicating channel of the balancing liquid is communicated with the balancing channel pointed to a center of rotation. The balancing channel is communicated with an emptying channel opened to atmosphere.

Abstract: Energy storage devices for storing energy are provided. An energy storage device includes a flywheel disposed in a chamber of a journal. A gas bearing is formed between an outer face of the flywheel and an inner face of the journal. The gas bearing exerts a compressive force on the flywheel, which allows for higher rotational velocities and higher energy storage.

Abstract: The present invention provides a compensator assembly for use in a motorcycle. The compensator assembly includes an input member, and an output member driven by the input member through a torque-buffering interface. The compensator assembly also includes one or more lubrication passageways formed therein extending between a distal end and one or more interfaces to provide lubricant thereto.

Abstract: Disclosed is a torsional vibration damper arrangement, especially for the drive train of a vehicle, including a primary side and a secondary side which is coupled to the primary side by a damper fluid arrangement in order for the primary side and the secondary side to rotate about an axis of rotation and rotate relative to one another. The damper fluid arrangement encompasses a first damper fluid that has low compressibility and transmits torque between the primary side and the secondary side as well as a second damper fluid which is more compressible and is loaded when the pressure of the first fluid increases.; The torsional vibration damper arrangement is characterized in that a volume containing the second damper fluid is disposed outside the primary side and outside the secondary side and does not rotate about the axis of rotation along with the primary side and the secondary side.

Abstract: An inertial navigation system is provided. The system includes a sensor block, an outer shell that substantially surrounds the sensor block and a plurality of gas pads connected to the outer shell that float the sensor block in gas creating a near frictionless environment to allow the sensor block to rotate in all directions. Each of the plurality of gas pads is adapted to receive pressurized gas. The outer shell and the sensor block are separated by a gap created by the pressurized gas at each pad.

Abstract: A torsional vibration damper has a drive side transmission element connected to a drive; a takeoff side transmission element, which can be brought into working connection with a takeoff and which can rotate with respect to the drive side transmission element; and a damping device installed between the two transmission elements, the damping device being equipped with a spring system, which serves to transmit torque between the drive side and the takeoff side transmission element and has at least one reservoir space containing a gaseous medium. Each reservoir space of the spring system is in working connection with an assigned pressure space of a pressure circuit containing a fluid medium, where the pressure circuit can be used to adjust the pressure present in the pressure space when the torque to be transmitted by the spring system changes and thus to adapt the characteristic of the spring system to the new torque as needed.

Abstract: In a flywheel having variable inertia, first and second guide grooves are respectively formed at a body and a rotatable member such that an overlapping position thereof is varied according to a relative rotation thereof. A movable mass is disposed at the overlapping position, and the rotatable member rotates relatively to the body by hydraulic pressure.
