Abstract
Torque information of a rotating machine may be determined by counting a number of discrete samples representing a rotation of a rotating component. If the number of discrete samples representing the rotation of the rotating component changes, it may be assumed that the torque has changed due to a change in loading placed on the rotating machine. The amount of change in torque may be determined by determining the amount of change in the number of discrete samples representing the rotation of the rotating component.
Claims7
A method of estimating torque applied to a rotating component of a production gearbox, the method comprising the steps of:
- providing empirical data relating torque to a number of sample readings between complete revolutions of a rotating component of a test gearbox;
- counting a number of sample readings between complete revolutions of a rotating component of the production gearbox;
- comparing the counted number of sample readings of the rotating component of the production gearbox to the number of sample readings between complete revolutions of the rotating component of the test gearbox contained in said empirical data;
- and
- estimating torque applied to the rotating component of the production gearbox based on said comparison.
