Abstract:
(EN) A mating member 8a rotates in the direction of an arrow D2. A washer 1 rotates in the direction of an arrow D1 in accompaniment with the rotation of the mating member 8a. In the gap between a tapered section 12a and the mating member 8a, a lubricant flows in a -θ direction viewed from the washer body, and the lubricant flows into a region Ra that gradually becomes narrower in the -θ direction. A "wedge effect" occurs thereby, and the pressure increases in the gap between a first surface 10a and the mating member 8a. In the gap between a tapered section 12b and a mating member 8b, the lubricant flows in a +θ direction viewed from the washer body, and the lubricant flows into a region Rb that gradually becomes wider in the +θ direction. An effect that is opposite the "wedge effect" occurs thereby, and the pressure decreases in the gap between a second surface 10b and the mating member 8b.
(FR) Un élément d'accouplement (8a) tourne dans la direction d'une flèche (D2). Une rondelle (1) tourne dans la direction d'une flèche (D1) en accompagnement de la rotation de l'élément d'accouplement (8a). Dans l'espace entre une section conique (12a) et l'élément d'accouplement (8a), un lubrifiant s'écoule dans une direction -θ vue depuis le corps de rondelle, et le lubrifiant s'écoule dans une région (Ra) qui s'étrécit progressivement dans la direction -θ. Un « effet de coin » se produit ainsi, et la pression augmente dans l'espace entre une première surface (10a) et l'élément d'accouplement (8a). Dans l'espace entre une section conique (12b) et un élément d'accouplement (8b), le lubrifiant s'écoule dans une direction +θ vue à partir du corps de rondelle, et le lubrifiant s'écoule dans une région (Rb) qui s'élargit progressivement dans la direction +θ. Un effet qui est opposé à l'« effet de coin » se produit ainsi, et la pression diminue dans l'espace entre une seconde surface (10b) et l'élément d'accouplement (8b).
(JA) 相手部材8aが矢印D2方向に回転する。ワッシャ1は、相手部材8aの回転に伴って矢印D1方向に回転する。テーパ部12aと相手部材8aとの隙間には、ワッシャ本体から見て-θ方向に潤滑油が流れ、-θ方向に徐々に狭くなる領域Raに潤滑油が流れこむ。これにより「くさび効果」が生じ、第1面10aと相手部材8aとの隙間の圧力は上昇する。一方、テーパ部12bと相手部材8bとの隙間には、ワッシャ本体から見て+θ方向に潤滑油が流れ、+θ方向に徐々に広くなる領域Rbに潤滑油が流れこむ。これにより「くさび効果」とは逆の効果が生じ、第2面10bと相手部材8bとの隙間の圧力は下降する。
