Abstract:
1. A method for calibrating a torsion torquemeter including: a power shaft configured to transmit rotational torque about an axis, the power shaft including a first wheel carrying a first and second series of angular reference points; a reference shaft including a first end attached to one end of the power shaft and a second end including a second wheel carrying a third and fourth series of angular reference points, the angular reference points of the first and third series being parallel to each other, and the angular reference points of the second and fourth series being parallel to one another while being inclined relative to the reference points of the first and third series; a measuring device to measure a first angular offset between two reference points respectively belonging to the first and third series of angular reference points, and a second angular offset between two reference points respectively belonging to the second and fourth series of angular reference points; a calculation unit to determine a torque value output by the power shaft on the basis of the first and second angular offsets measured by the measuring device; the method comprising:
