Abstract
(EN)
Provided are a sealing device that can prevent resting leakage of an object to be sealed without increasing sliding resistance with respect to an axle, and a surface treatment method for a sealing device disc member that can easily treat the surface of the disc member, such as a slinger, of the sealing device. The surface treatment method for a sealing device disc member in which a plurality of spiral micro grooves are formed on the surface (31d) of a disc member (3) of the sealing device is characterized in that a grinding member (64) having a plurality of minute projections is moved toward the outer edge (arrow c) while pressing against the surface (31d) of the disc member (3) relatively rotating about an axis (y). The sealing device is characterized in that a face on the other side of the flange is provided with a slinger (3) on which the plurality of spiral micro grooves are randomly formed.

La présente invention porte sur un dispositif d'étanchéité qui peut empêcher une fuite de repos d'un objet à sceller sans augmenter la résistance au glissement par rapport à un axe, et sur un procédé de traitement de surface pour un élément de disque de dispositif d'étanchéité qui peut facilement traiter la surface de l'élément de disque, telle qu'une bague d'étanchéité, du dispositif d'étanchéité. Le procédé de traitement de surface pour un élément de disque de dispositif d'étanchéité dans lequel une pluralité de micro-rainures en spirale sont formées sur la surface (31d) d'un élément de disque (3) du dispositif d'étanchéité, est caractérisé en ce qu'un élément de meulage (64) ayant une pluralité de minuscules saillies est déplacé vers le bord externe ( flèche c) tout en appuyant contre la surface (31d) de l'élément de disque (3) tournant relativement autour d'un axe (y). Le dispositif d'étanchéité est caractérisé en ce qu'une face sur l'autre côté de la bride est pourvue d'une bague d'étanchéité (3) sur laquelle la pluralité de micro-rainures en spirale sont formées de manière aléatoire.
