ABSTRACT:
A tensioning device constructed, in particular, as a double eccentric tensioning device for a traction means drive is provided, which guarantees in the installed state a sufficient pretensioning of a traction means of the traction means drive. The invention provides advantages in the installation of the eccentric tensioning devices under assembly-specific aspects. This is provided by an eccentric tensioning device for a traction means drive, with a track roller device, which includes a running disk and a rolling bearing provided for supporting the disk. An operating eccentric for supporting the track roller device such that it can be displaced in a radial direction relative to the rotating axis of the rolling bearing according to a magnitude of the pivoting of the operating eccentric, and a torsion spring for pretensioning the operating eccentric in a pivoting direction are provided. The operating eccentric forces the track roller device carried by the eccentric against an allocated traction means. An adjustment eccentric for radial displacement of the operating eccentric is provided, and a fixing device for securing the operating eccentric in a mounting position, in which the torsion spring is held via a shearing structure. In this way, it is possible in an advantageous way to set the tensioning device as a pretensioned unit on the flange surface and to trigger activation of the tensioning device within the scope of the mounting measures caused with the attachment of the tensioning device.
