Abstract
A system for determining the suitable positioning of a first gear wheel in relation to a second gear wheel. The system comprises an evaluation unit and a roll-of device, which contains a first spindle for the rotatable seating of the first gear wheel, a second spindle for the rotatable seating of the second gear wheel and a drive mechanism for rotating the first gear wheel and a drive mechanism for acting with a positive or a negative torque on the second gear wheel. The roll-off device furthermore has a displacement device for changing the positioning of the first gear wheel in relation to the second gear wheel. A measurement pick-up device and two angle encoders are provided in the roll-off device and are connected with the evaluation unit. The evaluation unit processes coordinate information S(X, Y, Z), which describes the positioning of the first gear wheel in relation to the second gear wheel, the continuous signal from the measurement pick-up device, and signals from the two angle encoders, in order to determine the suitable positioning.
