Abstract

A tensioner for a power transmission element of a traction drive, includes a housing, a swivel arm having a free end for connection to a rotatable tension roller which rests on the power transmission element, and a swivel bearing, including an axle for connection to the swivel arm and a bushing forming part of the housing and supporting the axle, for rotatably supporting the swivel arm in the housing. A spring is positioned in a peripheral zone of the swivel bearing between the swivel arm and the housing. Mounted in fixed rotative engagement to the axle and supported by the housing via a friction lining is a friction disk, with a disk-shaped first dampening element positioned between the friction lining and the housing.
