Abstract
A belt drive for driving a rotatably mounted object, includes a main part, at least two belt wheels, a device for generating a pretensioning force, and a continuously circulating belt which loops around the belt wheels. The first belt wheel is connected to or can be connected to a drive, and the second belt wheel is connected to or can be connected to the object. The invention is characterized in that the device has at least two rollers which are attached to opposite sides of a lever that is pivotally mounted on the main part, and each roller contacts a section of the belt, wherein the lever is acted upon by at least one spring element and can be moved relative to the main part.
Claims20
A belt drive comprising:
- a base body and a first belt wheel and a second belt wheel, the first belt wheel being connected or connectable to a drive, and the first belt wheel and the second belt wheel each being rotationally supported about a respective rotational axis,
- an endlessly circulating belt wrapped around the first belt wheel and the second belt wheel,
- a lever pivotably supported about a pivot axis on the base body by a pin, and
- at least two rollers mounted on opposite sides of the lever, each of the at least two rollers contacting a respective section of the belt,
- the lever is loaded by at least one spring element,
- the pivot axis of the lever is positioned between the rotational axis of each of the first belt wheel and the second belt wheel,
- the pin is displaceable such that the lever is both rotatable and displaceable, and
- a centerline extends through center points of the first belt wheel and the second belt wheel, and the pin is displaceable along the centerline.
A belt drive comprising:
- a base body and a first belt wheel and a second belt wheel, the first belt wheel being connected or connectable to a drive, and the first belt wheel and the second belt wheel each being rotationally supported about a respective rotational axis,
- an endlessly circulating belt wrapped around the first belt wheel and the second belt wheel,
- a lever pivotably supported about a pivot axis on the base body by a pin, and
- at least two rollers mounted on opposite sides of the lever, each of the at least two rollers contacting a respective section of the belt,
- the lever is loaded by at least one spring element, the pivot axis of the lever is positioned between the rotational axis of each of the first belt wheel and the second belt wheel, the pin is displaceable such that the lever is both rotatable and displaceable, and
- the lever has a two-part construction including two links that are axially spaced from each other along the pivot axis, and the rollers and the pin are axially held between the two links.
A belt drive comprising:
- a base body and a first belt wheel and a second belt wheel, the first belt wheel being connected or connectable to a drive, and the first belt wheel and the second belt wheel each being rotationally supported about a respective rotational axis,
- an endlessly circulating belt wrapped around the first belt wheel and the second belt wheel,
- a lever pivotably supported about a pivot axis on the base body by a pin, and
- at least two rollers mounted on opposite sides of the lever, each of the at least two rollers contacting a respective section of the belt,
- the lever is loaded by at least one spring element, the pivot axis of the lever is positioned between the rotational axis of each of the first belt wheel and the second belt wheel, the pin is displaceable such that the lever is both rotatable and displaceable, and
- a groove is defined in the base body, and the pin is engaged within the groove such that the pin is slidable within the groove.
