- 論文の詳細を見る
For elucidating the effect of tooth fatigue on dynamic performance of case-hardened gears, the gears were fatigue-tested by a power circulating gear testing machine, and tooth root strain, vibration acceleration level, sound pressure level and so on were measured. The tooth failure mode was classified into two types; a tooth breakage by bending fatigue at the tooth fillet and a tooth breakage due to surface fatigue near the pitch point. In the same failure mode, the changing pattern of sound pressure level was the same even if the surface hardening method was different. The dynamic load, vibration and noise tended to increase as the tooth profile deteriorated.
