| Abstract(J) | 軸受等で発生する電食は，モーターの漏れ電流が起因となる．本現象は，摺動部に介在する潤滑油を介した通電により溶損が生じ，損傷に至るものである．そこで本研究では，摺動部の潤滑状態および潤滑油の特性に着目し，それらが電食に及ぼす影響を実験的に明らかにした． Translation |
| Abstract(E) | Electrolytic corrosion in bearings and similar components is caused by motor leakage current. This phenomenon occurs when current flows through the lubricating oil in sliding interfaces, leading to electrical discharge machining (EDM) and subsequent damage. In this study, we focused on the lubrication state and the properties of the transmission fluid to clarify their influence on electrolytic corrosion through experimental analysis. |
