• 論文の詳細を見る

• The mechanism of hydrodynamic load capacity generation on a slideway is analyzed theoretically and experimentally.It is found that oil inlet pressure is an initial source for the development of this mechanism.At low Reynolds number, oil inlet pressure develops due to viscous drag of oil ahead of the oil inlet into narrow inlet passage, rather than to inertia force.The moment that develops as a product of oil inlet pressure generates a wedge geometry on bearing surfaces, whose surface separation is initially parallel in the stationary state.Initiated by oil inlet pressure, the wedge geometry is considered as the mechanism for generating hydrodynamic load capacity.Taking metallic contacts into consideration, the variation of frictional coefficient with sliding velocity can be estimated.Then, theoretical results are compared with experimental ones.
