抄録

In this paper, an induction-hardened sintered powder metal spur gear was compared with an induction-hardened steel spur gear in terms of dynamic performance using a power circulating gear testing machine. Tooth root strain, vibration acceleration of gear box and sound pressure near gear box were measured at rotational speeds of 1 600 rpm to 10 000 rpm. The tooth root strain was analyzed at time-frequency domain by wavelet transform. The dynamic performance of the sintered powder metal gear was superior to that of the steel gear. The vibration acceleration and the sound pressure of the sintered powder metal gear were lower than those of the steel gear. According to the result of the time-frequency analysis of the tooth root strain by wavelet transform, it was clear that the damping characteristic of the sintered powder metal gear was superior to that of the steel gear.
