Abstract:
The present disclosure is directed toward a method for measuring a true concentricity of a rotating shaft. The method includes simultaneously measuring, with diametrically opposed position sensors, opposite sides of the rotating shaft at an initial state to acquire a first measurement data and at a 180-degree rotation to acquire a second measurement data. The method further determines a rotational centerline and a shaft centerline based on the first and second measurement data, and calculates a concentricity error of the rotating shaft based on the determined rotational centerline and the shaft centerline.

Claim (Index 15):
The method of  claim 11 , wherein:\n the first measurement data and the second measurement data include positional measurements of the opposite sides of the rotating shaft relative to the two-dimensional optical sensor, and the determining one or more rotating shaft centerlines further comprises:\n measuring a first shaft diameter and a second shaft diameter, wherein the first shaft diameter is measured based on the positional measurements of the opposite sides of the shaft acquired in the first measurement data, and the second shaft diameter is measured based on the positional measurements of the opposites sides of the shaft acquired in the second measurement data; \n calculating a first shaft centerline based on the first shaft diameter, and calculating a second shaft centerline based on the second shaft diameter, and \n further wherein the concentricity error is calculated based on the first shaft centerline, the second shaft centerline, and the rotational centerline.
