Abstract

By converting the alignment issue of multiple span rotary shafts into a non-connected shaft alignment issue, we present a precision alignment strategy for multiple span shafts, and a laser-based method for measuring misalignment of non-connected shafts is proposed. The quadrant photodiode detector was calibrated at different rotation angles to obtain the sensitivity coefficient. According to the calibration results, the experiment scheme of the method was optimized. Then measurement experiments were carried out and the error source, the measurement uncertainty of the results were analyzed. Finally, the misalignment was also measured by a coordinate measuring machine, and the comparison results show that the relative error of the two methods is less than 5%. Therefore, the proposed method can be applied to align multiple span shafts accurately. Furthermore, this method can also be used for non-connected shaft position determinations such as wheel alignment inspections, alignment of machine spindle and center shaft, and others.
