Tensioning device () for a traction mechanism drive, such as a belt or a chain drive, with a tensioning arm (), which can pivot about a pivot axle () relative to a body () and on whose distal end there is a roller () supported so that it can rotate for tensioning the traction mechanism, for the purpose of which there is a torsion spring () acting between the pivot axle () of the tensioning arm () and the body (). The pivot axle () is supported in a sliding manner by at least one radial bearing arrangement () and at least one axial bearing arrangement () separated from this radial bearing arrangement, and the axial bearing () is constructed as a cone friction bearing and includes a cone bearing disk (), which is locked in rotation with the pivot axle () and is guided subjected to friction on the end against a cone bearing surface () formed in the hub section of the tensioning arm ().

A friction wheel drive, especially for driving an auxiliary unit of an internal combustion engine in a frictionally engaging manner is provided. The friction wheel drive includes an adjustable friction wheel () which can be pressed at least against a contact disk () of an output member () and/or an input member (). In order to create a particularly simple, mechanically operating friction wheel (), the friction wheel is provided with a running disk () which is mounted on a rolling bearing () that is fixed to the engine. The running disk () includes a tapered annular groove () having a width that can be varied by axially movable, spring-force impinged sidewalls (). Further, a friction ring () having a diameter that is larger than that of the tapered annular groove () is inserted into the groove such that the friction ring () is disposed eccentric to the same, is guided in a radially movable fashion, and is spring mounted.
