レーザ光を用いた歯車歯面損傷診断の実用化検討

抄録

We developed an automatic damage diagnosis system of the gear tooth surface using a laser beam. Only attaching a laser sensor in a gear box, we can grasp the size and place of the damage on a gear tooth surface without using a rotary encoder. We confirmed the limit of this method against the velocity fluctuation. Furthermore, to utilize this system in the practical field, we developed a new system which was small, light weight, and low cost. The accuracy between new and conventional system was compared, and we confirmed the results were comparable level.
