Abstract: A crankshaft assembly which is designed for a reciprocating-piston machine of an internal combustion engine includes a crankshaft, a torsional vibration damper for damping resonance torsional vibrations of the elastic torsion modes of the crankshaft, and an output. The torsional vibration damper has a primary mass inertia and a secondary mass inertia, the primary mass inertia being rigidly connected to a crankshaft and the secondary mass inertia being coupled as a seismic mass with a viscous liquid to the primary mass inertia. The torsional vibration damper is configured to assume the function of a flywheel for reducing rotational non-uniformity in addition to the function of reducing the resonance torsional vibrations of the crankshaft.

Abstract: A coupling for transmitting torque from a drive to a load has a first connection for connection with the drive, a second connection for connection with the load, and an elastic element for vibration damping and between the first and second connections in the energy transmission path therebetween. An actuator carried on the elastic element has a base body and a centrifugal mass body rotatable relative thereto.

Thus a flow of current through the conductor makes the centrifugal mass body exert an angular force on the base body to compensate for rotational vibrations.

Abstract: An adapter for fitting a flywheel housing to a rotary load has a generally circular centering plate having a central circular aperture dimensioned to fit snugly around the load's collar and a circular outer periphery. The centering plate is formed with first and second arrays of holes equispaced from a center of the aperture.

An adapter plate engaged flatly with the centering plate is formed with a first array of at least two holes spaced identically to and alignable with the formations, and is stiffened. Respective fasteners are engageable, when the first-array holes of both plates are aligned with the formations of the load, through the adapter plate, centering plate, and fastener formations. The second-array holes of the circular centering plate are covered by the adapter plate when the plates are thus fastened together.
