Abstract:
1. Device for measuring and aligning a first component and a second component relative to each other, where the first component comprises a first shaft and the second component comprises a second shaft which are intended to be aligned in a predetermined relationship to each other, and where the device comprises a first detector unit disposed to be mounted on the first shaft and a second detector unit disposed to be mounted on the second shaft and a control unit which is connected to the first detector unit and the second detector unit, characterized in that the device further comprises a first geometric pattern disposed on the first detector unit and a second geometric pattern disposed on a second detector unit, the position of the first geometric pattern being detectable by the second detector unit and the position of the second geometric pattern being detectable by the first detector unit, where the device is disposed to detect angular deviations and parallel deviations from the case where the shafts are considered to be aligned with each other, by analyzing with the control unit the detected position of the respective geometric pattern, and where said angular deviations and parallel deviations are detected by measurement of the change in position of said patterns, at least two different axial rotational positions of the shafts.
