A tensioning device for attraction mechanism including a receiving and mounting housing, a roller carrier pivotably connected to the mounting housing, a bearing which radially supports the roller carrier relative to the mounting housing, a spring between the roller carrier and the mounting housing for applying a tensioning force, and a damping device. The damping device includes a damping bush which, by friction, dampens any movement between the roller carrier and the mounting housing in such a way that damping is greater in the direction of an increasing tension force than in the direction of decreasing tension force. A flat band spring applies the friction force to the damping bush. The flat band spring is secured, at a first end, to the receiving and mounting housing in a rotationally fast way, and at a second end to the damping bush in a rotationally fast way.

Belt tensioning device

A belt tensioning device for traction mechanisms includes a receiving and mounting housing, a pulley carrier pivotally connected to the receiving and mounting housing, a bearing supporting the pulley carrier relative to the receiving and mounting housing, and a spring located between the pulley carrier and the receiving and mounting housing for applying the tensioning force. The belt tensioning device, in normal operation, on the slack side between a generator and a main pulley can also be used when the slack side becomes the load side by a blocking mechanism which enables swinging motion of the pulley carrier relative to the receiving and mounting housing in a first direction, and limits or prevents such motion in a second, opposite direction.

Tensioning means for traction mechanisms, especially belt tensioning means

The invention relates to belt tensioning device (1) with a receiver housing (2), a roller carrier (3) connected to the receiver housing (2), a spring-loaded bearing means (5) between the receiver housing (2) and the roller carrier (3), and a spring element (6) which acts between the receiver housing (2) and the roller carrier (3) for applying a tensioning force. To simplify the structure of belt tensioning device (1) and to cut production costs, according to the invention, the spring element (6) used for spring loading of the bearing means (5) in addition to being used for applying the belt tensioning force to the pulley carrier.
