Abstract:
A rotational vibration damper, comprising:a first damping component rotatably mounted about a rotational axis;a second damping component rotatably mounted about said rotational axis and rotatable relative to said first damping component;a coupling mass arrangement having a center of gravity and pivotally connected to said first damping component about a pivot axis that is offset and axis-parallel relative to said center of gravity and to said rotational axis;said coupling mass arrangement comprising first and second contact surface regions facing away from each other and arranged at a distance from each other along a circumferential direction; andsaid second damping component comprising first and second counter-contact surface regions facing toward each other and arranged at a distance from each other along the circumferential direction, said first and second counter-contact surface regions respectively contacting said first and second contact surfaces of said coupling mass arrangement for transmitting rotational force between said first and second damping components.
