Abstract:
(EN) [Problem] To obtain a structure wherein water having entered the gap between the bottom surface of an annular groove in a rotation-side flange and the axial inner surface of a rotating body for braking can be easily discharged to the outside space. [Solution] The outer diameter DO of an annular groove 15 is greater than the diameter DDI of the circle inscribing the axially outer openings of water drain holes 17a and is smaller than the diameter DDO of the circle circumscribing the axially outer openings of the water drain holes 17a.
(FR) [Problème] Obtenir une structure dans laquelle l'eau ayant pénétré dans l'espace entre la surface inférieure d'une rainure annulaire dans une bride côté rotation et la surface interne axiale d'un corps rotatif pour le freinage peut être facilement évacuée vers l'espace extérieur. [Solution] Le diamètre extérieur DO d'une rainure annulaire (15) est supérieur au diamètre DDI du cercle inscrivant les ouvertures axialement extérieures de trous de drainage d'eau (17a) et est inférieur au diamètre DDO du cercle circonscrivant les ouvertures axialement extérieures des trous de drainage d'eau (17a).
(JA) 【課題】回転側フランジの環状溝の底面と、制動用回転体の軸方向内側面との間に存在する隙間内に浸入した水分を、外部空間に容易に排出できる構造を実現する。 【解決手段】環状溝15の外径DOが、水抜き孔17aの軸方向外側開口部の内接円の直径DDIよりも大きく、水抜き孔17aの軸方向外側開口部の外接円の直径DDOよりも小さい。
