Abstract
A method for determining belt wear in a belt drive, wherein the belt is loaded with a defined torque and the rotation angle of a pulley is determined.
Claims12
A method for determining belt wear in a belt drive, the method comprising
- loading a belt (5) with a defined torque on a pulley (4), and
- determining, with a sensor, a rotation angle (φ) of the pulley (4) as a measure for the belt wear,
- wherein the belt drive (5) includes the pulley (4) and at least one tensioning arm (8, 9) which is mounted pivotably on the pulley (4) and which is connected to a tensioning roller (6, 7), and
- wherein the belt (5) is guided around the pulley (4) and the tensioning roller (6, 7).

A method for determining belt wear in a belt drive, the method comprising
- loading a belt (5), on a pulley, in opposite directions with defined torques, and
- determining, with a sensor, an overall rotation angle (φ) of the pulley (4) as a measure for the belt wear,
- wherein the belt drive includes two tensioning arms (8, 9) which are mounted pivotably on the pulley (4) and which are each connected to a tensioning roller (6, 7), and
- wherein the belt (5) is guided around the pulley (4) and the two tensioning rollers (6, 7).
1 more element
A method for determining belt wear in a belt drive, the method comprising
- loading a belt (5) with a defined torque on a pulley (4), and
- determining, with a sensor, a time that the pulley (4) takes to reach a deflection corresponding to the defined torque as a measure for the belt wear,
- wherein the belt drive (5) includes the pulley (4) and at least one tensioning arm (8, 9) which is mounted pivotably on the pulley (4) and which is connected to a tensioning roller (6, 7), and
- wherein the belt (5) is guided around the pulley (4) and the tensioning roller (6, 7).
