A tensioner for a belt, a chain or the like, which has a tensioning lever that is in operative connection with a helical spring, is pivotable about a fixed axis and on the tensioning lever a receptacle for a tensioning element that bears against the belt, chain or the like is arranged. The helical spring is held at its ends by spring receptacles with the helical spring being screwed to at least one of the spring receptacles. This construction ensures a reliable and easy-to-assemble connection between the helical spring and the spring receptacle is achieved.

Tensioner for a traction means such as a belt or the like

The invention relates to a clamping device comprising a pivoting arm on which a clamping roll is rotatably arranged. In order to damp pivoting movements of the pivoting arm, a damping device is provided in the region of a pivoting axis X. Furthermore, the pivoting arm is supported by a tension spring device which ensures a frictional arrangement of the clamping roll on a traction mechanism, in the assembled state.

Tensioning device

A tensioner (') for a traction mechanism such as a belt, chain or the like, with a tensioning lever () which can be acted on by a helical spring (), can pivot about a stationary shaft and on which a tensioning element is provided for abutment against the traction mechanism to be tensioned. The helical spring () is held at its ends by spring receptacles () and a means () is provided for delimiting the spring excursion.

Tensioner for a traction mechanism

A tensioning device for a traction mechanism, particularly a belt or a chain, including a tensioning lever over which the traction mechanism is guided and on which a tensioning spring is disposed with one end thereof, the other end thereof being provided on a spring holder by which the tensioning device can be fastened to an external object. A holding pin () extends through the tensioning spring (), with the pin at one end () thereof being disposed in a fixed position on the tensioning lever () and at the other end thereof having a locking section () disposed on a locking element () provided on a spring holder (). The locking element can be adjusted between a locking position of the holding pin end (), in which the tensioning device () is fixed in a position with the pretensioned tensioning spring (), and a released position of the holding pin end (), in which the holding pin () is axially displaceable in the locking element (), and limited by a stop.

Tensioning device for a traction mechanism, particularly a belt or a chain

The invention relates to a tension roller () for a fraction drive, comprising a washer () mounted on an antifriction bearing and a spacer (). A sealing cap () is provided between the washer () and the spacer () and allows for a captivated arrangement of all components of the tension roller.
