レーザ反射光を用いた安価・迅速な歯車歯面損傷診断システムの実用化

抄録

In the industrial field of making gear, it is difficult to check all gear products. To address this problem, we developed an automatic damage diagnosis system of the gear tooth surface using a laser beam. Only attaching a laser sensor, we can grasp the size and position of the damage immediately on a gear tooth surface without using a rotary encoder. This method can be diagnosed for spur, helical, and profile shifted gears. Furthermore, to utilize this system in the practical field, we developed a new system which was compact, lightweight, and low cost by using a touch panel and Raspberry pi. The accuracy between new and conventional desktop PC system was compared, and we confirmed the results were comparable level. Finally we did the damage diagnosis experiment to use this compact device in the real gear factory by workers. They could use it smoothly and verified the validity of this device.
