ABSTRACT:
A centrifugal mass device having at least two centrifugal masses which are rotatable relative to each other against the effect of elastic elements of a torsional damping device. The output-side centrifugal mass, which is more distant from a drive, e.g., the crankshaft of an internal combustion engine, is run radially as well as axially relative to the drive-side centrifugal mass via a support. The support has an axial slide bearing that borders a grease chamber containing a viscous medium, which grease chamber accommodates, at least partially, the torsional damping device. To form a seal for the grease chamber, the axial slide bearing is radially encompassed along at least a portion of its axial extension by at least one axial projection provided on at least one of the centrifugal masses, whereby the axial projection is close to but separated by a gap from an associated region of the other centrifugal mass.
