| Abstract(J) | 電気自動車用減速機として高周速トラクションドライブが注目されるが，高周速では発熱に対する冷却が課題である．本研究は潤滑方向別にローラ表面温度を測定し，かみ外れ潤滑で冷却効果が高いことを確認した．加えて，油膜流れを可視化することで，かみ外れ方向における冷却効果の定性的な原理解明を目指した． Translation |
| Abstract(E) | Traction drives at high peripheral speeds are attracting attention as reduction mechanisms for electric vehicles, but thermal cooling under high-speed operation remains a major issue. This study measured roller surface temperatures under different lubrication directions and confirmed that 'disengagement lubrication' provides superior cooling performance. Additionally, oil film flow was visualized to qualitatively investigate the mechanisms behind enhanced cooling in the 'disengagement lubrication' and to support a foundational understanding of the observed thermal behavior. |
