ABSTRACT:
A tensioning device (1) for belt or chain drives comprising a tension arm (3) which carries a tension roller (4) on one end and is mounted at a second end for rotating together with a shaft (6) in a housing (2) while being resiliently supported on the housing (2) by a torsion spring (16), the tensioning device (1) further comprising a friction disk (10) which is rigidly connected to the shaft (6) or the tension arm (3), a friction lining (15,24,27) being arranged between a friction surface (10a) of the friction disk (10) and an axial contact surface (14) of the housing (2), characterized in that the contact surface (14) comprises a means (23,25,28) which engages the friction lining (15,24,27) by positive and/or force engagement and prevents any rotation of said friction lining (15,24,27) with respect to the contact surface (14).
