Belt tensioning device for the drive of secondary assemblies in engines - has gap in vibration dampener between piston and friction body

At least one friction-reducing element is inserted between the parallel conical faces of the vibration dampener (11). This element can be endless worm springs (17) or standard O-rings of a polymer material. A conical ring could be used whose surfaces are designed as adhesive faces for fixing the rin...

Beschreibung
Zusammenfassung:	At least one friction-reducing element is inserted between the parallel conical faces of the vibration dampener (11). This element can be endless worm springs (17) or standard O-rings of a polymer material. A conical ring could be used whose surfaces are designed as adhesive faces for fixing the ring on the adjoining components. The friction body (12) can be a ring having a radial full-length slit at least one circumferential point. The ring adjoins the inner faces of the cylinder by a cylindrical sleeve face. The two conical faces of the vibration dampener can be formed on inner and outer conical sleeves (15,16). ADVANTAGE - The friction force dampening the vibration can be different in each direction of movement.
