Abstract
A torsional vibration damper is provided with a drive-side transmission element which engages with a driven-side transmission element via a planetary gear set. The planetary gear set includes a planet wheel mounted on a planet carrier. The planet wheel engages another element of the planetary gear set such as a ring gear. The planet wheel has a toothing at its outer circumference which engages a toothing of the ring gear. The toothing of at least one of the planet wheel and the ring gear is made from a material which obviates the requirement of lubricating the toothing engagement between the planet wheel and the ring gear.
