摘要： A compound helicopter includes a fuselage including a fuselage airframe, a translational thrust system coupled to the fuselage airframe and a pylon assembly subject to vibration. The pylon assembly includes a transmission and a rotor system having a main rotor assembly. The compound helicopter also includes a main rotor vibration isolation system including a plurality of augmented liquid inertia vibration eliminator units each having an isolation frequency and each coupled between the fuselage airframe and the pylon assembly to reduce transmission of the pylon assembly vibration to the fuselage airframe at the isolation frequency. Each augmented liquid inertia vibration eliminator unit includes at least one active tuning element movable to tune the isolation frequency thereof.

摘要： According to one embodiment, a damper device includes a rotator, a first oscillator, a second oscillator, and two rollers, for example. The rotator is provided with a first opening. The second oscillator includes two guide surfaces recessed in a direction closer to a first center of rotation and a transmitting part capable of moving along the first opening. The two rollers each include a ring supported by the first oscillator and a shaft extending along a second center of rotation inside the ring and rotatably supported by the ring. The shaft comes into contact with a corresponding one of the two guide surfaces of the second oscillator pushed outward in the radial direction by centrifugal force, rolls along the corresponding one of the two guide surfaces by oscillation of the first oscillator, and is pushed by the corresponding one of the two guide surfaces in the circumferential direction.

摘要： A power take off (PTO) gear including: an input flange including an outwardly extending protrusion; a ring gear; and a piston including an inwardly extending protrusion and a circumferential end. The PTO gear includes first and second cover plates fixedly secured to the ring gear; at least one elastic element engaged with the flange and the first and second cover plates; and a chamber bounded by the circumferential end of the piston and material forming the ring gear and sealed in first and second axial directions by the first and second cover plates, respectively. For first torque applied to the flange, the flange is arranged to rotate with respect to the ring gear such that: the inwardly and outwardly extending protrusions contacts; the flange displaces the circumferentially curved piston; and the circumferential end of the curved piston displaces fluid disposed in the chamber to dampen motion of the flange.

摘要： A balance ring for an appliance is provided that has features to control fluid distribution particularly during certain critical speeds where large oscillatory motion created by an out of balance condition might otherwise cause the balance ring fluid to redistribute improperly. The balance ring can include an inner chamber that is in fluid communication with an outer chamber. The inner chamber can include baffles that impede the movement of fluid along the circumferential direction when e.g., the balance ring experiences large oscillatory motion.

摘要： A viscous damper for driving accessories by a crankshaft though a viscous coupler of the viscous damper. The rotational driving force of the crankshaft is transmitted to the viscous damper hub through the meshing of a large diameter gear and a driven gear, the viscous damper forming a unit with the driven gear. The rotational driving force is further transmitted to a viscous damper housing through the hub and the viscous coupling means, i.e., the viscous coupling means comprising a number of plates which are movable relative to each other in a space filled with silicon oil. The rotational driving force, which is transmitted to the housing and is dampened in torque changes by the function of the coupling means, is transmitted to a rotor shaft of an alternator to smoothly rotate the alternator rotor. A smooth performance in driving the accessories is ensured by the viscous damper having the viscous coupling.

摘要： Apparatus for damping vibrations between the output element of the engine and the power train in a motor vehicle has flywheels which are rotatable relative to each other. One flywheel is mounted on the output element of the engine and another flywheel is connectable to the power train by a friction clutch. Vibration dampers are installed between the flywheels, and such dampers are confined in a housing which is provided on the one flywheel and contains a supply of viscous fluid medium for the parts of the dampers. The housing is the input member of the dampers and the output member of the dampers is a flange which extends into the housing and is axially movably coupled to the other flywheel.
