Abstract
A tension device for belts and chains with a tension arm (1) rotatably supported relative to a stationary machine element (6) and spring-loaded by means of a spring (12) against the traction means, on which tension arm, tension means, in particular a tension roller (2), are provided for bearing against the traction means, between the stationary machine element (6) and an element (7), disposed fixedly on the tension arm, are disposed in series a friction element (10) and a resiliently deformable spring element (11), and the resilient deformation of the spring element (11) is limited by the static friction acting between the element (7) fixedly disposed on the tension arm, and the stationary machine element (6) which avoids impermissibly high belt tensions and undesirably high tension arm excursions.
