Abstract
A flywheel device has at least two inertial masses which can rotate relative to one another against the action of elastic elements of a damping device, one of which inertial masses, namely the output-side inertial mass which is farther from a drive system, such as for example the crankshaft of an internal combustion engine, is guided both radially and axially by way of a bearing arrangement with respect to the input-side inertial mass. The bearing arrangement has at least one axial plain bearing and one radial plain bearing. Both plain bearings guide the output-side inertial mass with respect to the input-side inertial mass with a clearance, the size of which is determined so that when a wobbling motion is introduced from the crankshaft to the input-side inertial mass, the output-side inertial mass, under the effect of centrifugal forces, can perform a self-stabilization. The radial plain bearing, to bring it as close as possible to the crankshaft, is engaged in the vicinity of the end of the hub of the output-side inertial mass, which end faces the crankshaft.
