Abstract
The invention relates to a tensioning system for a belt or chain drive. Tensioners are known in which there are plastic friction bushes to damp oscillations where the coefficient of friction is adversely affected by temperature effects. It is the purpose of the invention to provide a tensioning system in which the friction coating retains a virtually constant frictional torque throughout its useful life. To this end, according to the invention there is a basic component (2) in which against a base (5) in the shape of a circular disc bears a friction coating (18) on which is supported a friction disc (10) which is secured against rotation by means of a shaft (7), to the tensioner (9) producing the oscillating movement.
