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.
Claims21
A tensioning device for traction means, comprising:
- a housing non-rotatably secured on an assemblage,
- a spring element having two ends and producing a spring force,
- a tensioning mechanism having two tensioning arms that are spring-biased by the spring element and mounted in the housing so as to be able to rotate with respect to one another and about at least one axis, and
- the assemblage having a drive shaft for driving the traction means, with the tensioning mechanism encompassing the drive shaft,
- wherein the tensioning mechanism and the spring element are disposed in the housing and adapted to tension the traction means, and
- wherein one end of the spring element is retained in one tensioning arm and the other end of the spring element is retained in the other tensioning arm, and
- wherein the tensioning mechanism is prefabricated as a separate complete assembly for installation on the assemblage.
The tensioning device of claim, 1, wherein the housing comprises a cylindrical housing part having a bottom section, a wall section and a cover section, wherein the wall section is mounted on a cylindrical surface of the assemblage.
