Abstract

A flywheel includes a hub sleeve, a stationary core surrounded by the hub sleeve, axially spaced first and second rolling-element bearings each having an inner ring supported on the core and an outer ring in engagement with the hub sleeve, an inner spacer sleeve disposed between the inner rings and surrounding the core and an outer spacer sleeve disposed between the outer rings and surrounding the inner spacer sleeve and a clamping arrangement axially urging the inner rings against the inner spacer sleeve and the outer rings against the outer spacer sleeve with a predetermined axial force. An axially yielding, relatively rigid spring element forms part of the clamping arrangement and engages at least one of the rings with the predetermined axial force. The spring element is substantially unyielding to the predetermined axial force, but yields to axial forces derived from vibrations imparted to the flywheel. Cooperating extensions of the spring element and and an outer ring constitute a labyrinth seal.
