Abstract: A belt tensioning device includes a first tensioning arm mounted on a base body pivotably about a first pivot axis and includes a rotatable first tensioning roller. A second tensioning arm is pivotably mounted relative to the base body about a second pivot axis and includes a rotatable second tensioning roller. Via a spring arrangement between the first tensioning arm and the second tensioning arm, the first and second tensioning arms are resiliently supported against one another in the circumferential direction. A damping mechanism is operatively arranged between the base body and the first tensioning arm for damping relative rotational movement between the first tensioning arm and the base body. The damping mechanism generates a varying damping torque dependent on the rotational position and/or rotational direction of the first tensioning arm relative to the base body upon pivoting of the first tensioning arm relative to the base body.

Abstract: A belt tensioning device comprises: a base member; a first tensioning arm, which is pivotably supported by a bearing sleeve on the base member around a first pivot axis and which comprises a first tensioning roller, wherein the bearing sleeve is configured radially elastically and is connected to one of the components, the base member and the first tensioning arm in a rotationally fixed manner, and which is rotatable relative to the other of the components, the base member and the tensioning arm a second tensioning arm, which is pivotably supported on the base member around a second pivot axis and comprises a second tensioning roller; a spring arrangement that pre-tensions the first tensioning arm and the second tensioning arm in circumferential direction relative to each other; pre-tensioning means, which that are arranged radially between a circumferential face of the bearing sleeve and a circumferential face of the component connected to the bearing sleeve to exert a radial force in direction relative to t

Abstract: A tensioning arrangement for a traction drive comprises a base member; at least one tensioning arm, which is pivotably mounted relative to the base member about a pivot axis; a tensioning roller that is connected to a carrier element of the at least one tensioning arm by a bearing so as to be rotatable about an axis of rotation; and an adjustment mechanism configured to pivot the bearing relative to the carrier element within a pivot range and to fasten the bearing in a pivot position within the pivot range. A corresponding device can be provided for adjusting the tensioning arrangement.
