Abstract: A decelerating device includes a fixed shaft, a tube, a transmission element and a driven element is provided. The tube is disposed around the fixed shaft and adapted to rotate about the fixed shaft. The transmission element has a fixed portion fixed at the fixed shaft and a planetary gear revolvably disposed at the fixed portion. The teeth of the tube are geared to the planetary gear. The driven element has a wheel, a sun gear fixed at the wheel and a plurality of balls. The sun gear and the wheel are revolvably disposed at the fixed shaft and in the tube. The planetary gear is adapted to drive the sun gear. The wheel has holes. Each of the holes extends from an outer surface of the wheel facing the tube to the interior of the wheel to form a cavity. The balls are disposed in the holes respectively.

Abstract: It is intended to provide a governor that is small, does not produce wear particles or noise, is low cost, is not affected by differences in attitude, is not affected by magnetism, and has outstanding durability. The governor has a rotor that rotates using energy supplied from an energy storage means through a power transfer means, a wing having wing surfaces perpendicular to the rotational axis of the rotor, and disposed movably to an outside circumference side radially to the rotor by means of centrifugal force produced by rotor rotation, a zigzag spring disposed between the rotor and wing for pulling the wing to the inside circumference side radially to the rotor, and an opposing member disposed to the outside circumference of the rotor and having an opposing surface located opposite and separated a predetermined gap from the wing surface when the wing moves to the outside circumference side radially to the rotor.

Abstract: A system and method for actively decelerating a combine rotor is provided. The system includes an electronic control system configured to disengage the combine rotor from an engine, to brake the combine rotor at a first deceleration rate for a first time interval, and to subsequently brake the combine rotor at another deceleration rate until the rotor is stopped.

Abstract: The power train of a motor vehicle has an engine which normally drives the wheels and can be started by an electric motor which acts as a generator once the engine is started. The torque transmitting connection between the crankshaft of the engine and a shaft of the motor includes a planetary and one or more freewheels of the type employing an elongated belt surrounding a rotary part and being surrounded by the internal surface of a hollow part. The belt or belts can be urged into or released from frictional engagement with one of the adjacent surfaces by centrifugal force and/or by an electromagnet.

Abstract: A two-speed centrifugally shifted automatic transmission provides an overdrive output shaft rotational speed that may be three times the rotational speed of the input shaft (12). A shift point at a partial speed may provide a direct drive through an overrunning clutch (33). A spline mounted shift engagement ring (46) is adapted to slide axially within housing (10) to restrain planet carrier ring (36) from rotating at start-up. After reaching a predetermined input shaft rotational speed, the shift engagement ring (46) moves to its extreme left position (FIG. 1), thereby allowing the planet carrier ring (36) to rotate and the rotational speed of the output shaft (14) to be driven by the overrunning clutch (33).
