The invention relates to an assembly method for a vibration damper of a tower of a wind power plant, in which the vibration damper is switched into a transport state from a state of use. The vibration damper is connected to a structural component of the tower such that a damper mass of the vibration damper can be set in motion, during which movement the distance between the damper mass and a central axis of the tower varies. The vibration damper is switched into the transport state by tilting the vibration damper compared to the state of use. The invention also relates to an associated assembly system.

A torque-sensing and transmitting device is provided. The device includes a transmission body, two vibration-damping members, two inner casings, two outer casings, a first circuit board module, and a battery module. The two inner casings are disposed on a shaft of the transmission body, and a vibration-damping member is disposed between the inner casing and the shaft. The first circuit board module is disposed in one of the two inner casings, and the first circuit board module is covered by a vibration-damping layer. The battery module is disposed on the other inner casing, and the battery module is covered by a vibration-damping layer. With the configuration of the vibration-damping member and the vibration-damping layer, this device solves the problem of the first circuit board module and the battery module being damaged due to vibration.

The invention relates to a torsional damper (210) in a clutch disc arrangement (200) arranged to indicate damping performance of the torsional damper (210). The torsional damper (210) comprises a driven plate (211), an output hub (212), intermediate friction plates (213) arranged on either side of the driven plate (211) and a resilient member (214) arranged to press the intermediate friction plates (213) against the driven plate (211) or against the output hub (212) with a pressure force. The intermediate friction plates (213) and the resilient member (214) are rotationally fixed to the output hub (212) or the driven plate (211) forming a rotationally fixed stack (213, 214, 212; 213, 214, 211). The rotationally fixed stack (213, 214, 212; 213, 214, 211) comprises a detection friction plate (215) rotatably decoupled from the rotationally fixed stack (213, 214, 212; 213, 214, 211) and arranged in the rotationally fixed stack (213, 214, 212; 213, 214, 211).

A damper with an integrated centrifugal pendulum-type vibration absorbing device is equipped with a drive plate for transmitting engine torque to a transmission. The drive plate has a stepped shape toward the annular outer edge. An annular side plate makes sliding contact with the outermost edge of the drive plate. An annular hub clutch is held between the side plate and the inside annular portion of the drive plate. Multiple torsion springs are arranged such that at least one end makes sliding contact with the hub clutch. A back plate grips the sides of the torsion springs, and is connected to the drive plate. Centrifugal pendulum-type vibration absorbing devices are mounted on a disc-shaped and circular back plate. Centrifugal pendulum-type vibration absorbing devices are mounted on the outer circumferential side of the back plate.
