Abstract (en)

[origin: WO2013004780A1] An alignment process for aligning a pair of mating shafts, wherein the alignment process utilizes a first laser sensor (212) attached to a first shaft (112) of a pair of mating shafts and a second laser sensor (222) attached to a second shaft (122) of the pair of mating shafts. The process determines an initially read erroneous radial displacement (324) and a backlash generated laser angular offset (234). The initially read erroneous radial displacement (324) and backlash generated laser angular offset (234) are entered into a geometric formula to determine a true radial displacement (310).
