Abstract
A tensioning device for traction means, especially for toothed belts, is provided with a tensioning arm (3) on which a tensioning roller (1) is rotatably arranged. Furthermore a stopper (12) is provided which restricts a swiveling angle of the tensioning arm (3), whereby a detachable locking device (15) is provided through which the tensioning arm (30) and the stopper (12) are locked for joint swiveling into a position provided for the stopper (12).

Tensioning device for traction means, comprising a tensioning arm (3), on which a tensioning roller (1) is rotatably arranged, and with a stopper (12) which restricts a swiveling angle of the tensioning arm (3), whereby a detachable locking device (15) is provided by which the tensioning arm (3) and the stopper (12) are locked together and are jointly swivelable into an adjustable installation position for the stopper (12), wherein the tensioning arm (3) and the stopper (12) are each provided with at least one arrangement (22, 23) which are provided for striking against each other, whereby the arrangements (22, 23) of the tensioning arm (3) and stopper (12) are set at a preset distance from each other in a swiveling direction of the tensioning arm (3) in the installation position.
Process for installing a prestressed tensioning device for a traction means drive, whereby the tensioning device comprises:
- a tensioning arm (3) on which a tensioning roller (1) is rotatably mounted,
- a support (4) on which the tensioning arm (3) is pivotably arranged,
- a tension spring (8) which is supported on the support (4) on one end and on the tensioning arm (3) on another end thereof,
- a stopper (12) which restricts a swiveling angle of the tensioning arm (3) and
- a detachable locking device (15) by which the tensioning arm (3), and the support (4) and the stopper (12) are lockable with one another,
- process comprising:
- locking the tensioning arm (3) and the support (4) and the stopper (12) with one another in an arrangement in which the tension spring (8) is prestressed,
- installing the tensioning device in the traction means drive,
- partially releasing the locking such that only the stopper (12) and the tensioning arm (3) are locked with each other by the locking device (15), whereby under force of the prestressed tension spring (8), the tensioning arm (3) is sprung against the traction means,
- fastening the stopper (12), and
- complete releasing of the locking such that the tensioning arm (3) is swivelable relative to the stopper (12).
