Swivel element of tensioning device, especially for endless drive belts in auxiliary drives of internal combustion engines, has working eccentric supporting tensioning roller, and support sleeve supporting end of torsion spring
The swivel element of a tensioning device, especially for endless drive belts, preferably in auxiliary drives of internal combustion engines, has an eccentric bolt (4) passing through the swivel element and supporting the tensioning device. A tensioning roller (20) is rotatably mounted on the eccentric bolt via a working eccentric (14). A supporting torsion spring (10) is provided in the swivel element. The swivel element is constructed in two sections, whereby the working eccentric supports the tensioning roller, and a support sleeve (12) axially connected to and positively locking with the working eccentric supports one end (28) of the torsion spring.
