ABSTRACT:
Tensioning device (1) for a traction element drive, such as a belt or chain drive, with a tensioning arm (4), which can pivot relative to a body (2) about a pivot axle (3) and on whose distal end a roller (5) supported rotatably is arranged for tensioning the traction element, for the purpose of which there is a torsion spring (6) acting between the pivot axle (3) of the tensioning arm (4) and the body (2), and the pivot axle (3) is supported so that it can slide by at least one radial-bearing arrangement (7) and at least one axial-bearing arrangement (8), wherein the axial-bearing arrangement (8) comprises a friction disk (9) arranged concentric to the pivot axle (3), wherein the friction disk (9) has an axial stop surface (11), which comprises at least one radial circumferential key groove (12) and that at least one radial circumferential friction spring, which extends into the key groove (12), is constructed in the surface adjacent to the stop surface (11) of the friction disk (9).
