Abstract
The invention concerns a tensioner for traction drives which includes a base element and a tension roller support arranged partly concentric with each other, and further including a torsion spring which is guided on a bush and braces these two elements against each other. According to the invention, a tension bush (20) which includes a longitudinal slot (21) is inserted between the bush (6) and the inner diameter of the torsion spring (13) so as to bear against the inner periphery of the torsion spring (13).
Claims7
A tensioner for traction drives, comprising a base element and a pivoting element in the form of a tension roller support arranged partially concentric with each other;
- a torsion spring guided on a bush for bracing the base element and the tension roller support against each other, said torsion spring causing a displacement of the tension roller support into an end position in which a tension roller tightens the tension drive, wherein the tension roller support is connected to a friction element for damping adjusting movements;
- and a tension bush (20) substantially corresponding in length to the tension spring (13) and comprising a longitudinal slot (21), said tension bush being inserted between the bush (6) and the torsion spring (13) so as to bear against an inner periphery of the torsion spring (13).
