摘要： A torsional vibration dampener for dampening torsional vibrations of a rotationally driven shaft. A hub is axially connected to the shaft, and a rotationally symmetrical body of inertia that acts as a vibrational mass is connected to the hub by a rubber elastic ring. The body of inertia comprises a primary part and a secondary part that is coaxial therewith and pivotable thereto. Displacement chambers are formed by and disposed between the primary and secondary parts. At least two displacement chambers communicate with one another via at least one flow control mechanism. Relative movement between the primary and secondary parts alters the volumes of the displacement chambers such that the volume of one decreases by the amount by which the other increases. The displacement chambers are filled with hydraulic fluid to form a fluid coupling between the primary and secondary parts such that upon relative movement between them, due to the resulting change in volume of the displacement chambers hydraulic fluid flows from one displacement chamber into the other via the flow control mechanism.

摘要： This invention is directed at torsional vibration dampers of a rotating shaft. The dampers of the invention provide self-tuning to dampen harmonics, over a broad range of shaft angular velocities. Where the shaft rotates with an angular velocity about a longintudinal axis, and rotates perpendicular to a plane of rotation, the damper comprises: at least one passive damping element, and one controlling damping element.

摘要： A clutch of a periodically-activated prime mover or driven machine having an integrated speed-adaptive damper. The damper is mounted directly on a connected flywheel, and a clutch plate and a pressure plate are arranged between the flywheel and the damper. The damper, in the area of its inner circumference, has a support for a clutch-actuation device, and the clutch-actuation device has a force-originating lever part and a spring part independent of the force-originating lever part.

摘要： Low excitation frequencies of a structural component, for example of a heopter rotor blade or the like, are damped or eliminated by a pendulum device connected to the component, the excitation frequency or frequencies of which are to be damped or eliminated. In a helicopter rotor blade the pendulum device is preferably connected to the blade neck near the rotor head. The pendulum device has a plurality of pendulum bodies coupled to each other for forming a multiple pendulum in which these pendulum bodies are so tuned relative to each other that the multiple pendulum has several eigenfrequencies.
