【Abstract】 The paper presents a new method, which is applied in the axis alignment of a mechanically rotary system by means of PSD (position sensitive detector) and laser technology. The method is mainly used in the axis alignment of a rotary axle. Owing to a high precision of bearings, the displacement error of axis is mainly dependent on the side play amount of axle center in the bearing hole. So it can meet the needs in practice to align the axis of bearing hole. The paper presented a detailed description to the principle of measurement and instrumentation system, deduced the calculating formulae of the side play amount of axle center, and gave out the results of the experiments. Meanwhile, all kinds of the factors influencing the precision of measurement were analyzed. According to the theoretical calculation and experiments, this method is of a high precision and reliability and has a wide range of applying prospect.更多还原
