Abstract
Tensioning device for traction means, such as belts or chains, with a housing-like part in which a tensioning mechanism and a spring elements tensioning the traction means are mounted, whereby the tensioning device can be placed in an assemblage of the traction means drive having a drive shaft so that the tensioning mechanism encompasses the drive shaft, with the housing-like part being disposed so as to prevent rotation, wherein the tensioning mechanism comprises two tensioning arms (7, 8, 26, 27, 47, 49) that are mounted in the housing-like part so as to be able to rotate about axes and with respect to one another, with the tensioning arms being spring-biased by a common spring element (14) that is retained with one end in one tensioning arm and with the other end in the other tensioning arm.
