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.

Belt tensioning device with a belt drive

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 the component rotatable thereto.

Belt tensioning device

A belt tensioning device for a belt drive which comprises a driving machine with a driving belt pulley drivable by a driveshaft around a driving axis, and a plurality of further belt pulleys and with an infinite belt which is wrapped around the driving belt pulley and the further belt pulleys wherein the belt tensioning device comprises a housing in which two tensioning arms are supported so as to be pivotable around a common pivot axis, in which tensioning arms there are supported tensioning rollers with axes of rotation extending parallel to the driving axis, wherein the tensioning arms are supported relative to one another by spring means, wherein, with the driving belt pulley mounted at the driving machine, the housing can be mounted in that, in an annular region surrounding the driveshaft of the driving belt pulley, the housing is contact-free relative to the driving machine.

Belt tensioning device for being used with a starter generator

A belt tensioning device for a belt drive having at least one apparatus with a housing, a driveshaft and a belt pulley, as well as an infinite belt for driving the belt pulley. The belt tensioning device includes a base that can be or is firmly connected to the apparatus, exactly one tensioning arm that, relative to the base, is supported so as to be pivotable around a pivot axis and that, via a torsion spring, is supported in the circumferential direction against the base. The belt tensioning device also includes a tensioning roller that, at the tensioning arm, is supported so as to be rotatable around an axis of rotation and serves to tension the belt. When the belt tensioning device is mounted at the apparatus, the pivot axis of the tensioning arm is arranged inside the outer diameter of the belt pulley of the apparatus.

A spring, especially for use in a belt tensioning device, with a number of at least 1.25 and at a maximum 2.5 coils, which extend around a spring axis A, wherein a first coil endhas an axial offset Va relative to a first coil region, arranged at an angle of 360&#xb0; around the spring axis A, and wherein a second coil endhas an radial offset Vr relative to a second coil regionarranged at an angle of 360&#xb0; around the spring axis A. A belt tensioning device and an assembly with such a belt tensioning device include such a spring.

Spring, belt tensioning device, and assembly

A belt tensioning device for a continuous belt drive. The device includes a torsion spring assembly () with a longitudinal axis (A) and with at least one torsion bar or torsion tube (). The torsion spring assembly () can be clamped axially and in a rotationally fast way into a rack. A tensioning arm (), at one end, is arranged at the torsion spring assembly () so as to be aligned approximately radially relative to the longitudinal axis (A). A tensioning roller () is rotatably fixed at the other end of the tensioning arm (). The axis of rotation (A) of the tensioning roller () extends substantially parallel relative to the longitudinal axis (A) of the torsion spring assembly (), and the tensioning arm () can be resiliently supported relative to the rack so as to oscillate around the longitudinal axis (A).

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.
