A sealing device used for a wheel bearing is provided. The sealing device is inserted into the wheel bearing, and includes a first insertion body and a second insertion body. The first insertion body has an annular first frame and a first sealing part coupled to the first frame. The second insertion body has an annular second frame having a diameter smaller than that of the first frame, and a second sealing part coupled to the second frame. The second insertion body rotates relative to the first insertion body around a rotary shaft. The first insertion body and the second insertion body are arranged such that a gap is formed between the first sealing part and the second sealing part. The first sealing part and/or the second sealing part has a lip having an annular shape around the rotary shaft. The lip has at least one groove on the surface thereof in the outward radial direction.

    L'invention concerne un dispositif d'étanchéité utilisé pour un palier de roue. Le dispositif d'étanchéité est inséré dans le palier de roue, et comprend un premier corps d'insertion et un second corps d'insertion. Le premier corps d'insertion a un premier cadre annulaire et une première partie d'étanchéité couplée au premier cadre. Le second corps d'insertion a un second cadre annulaire ayant un diamètre plus petit que celui du premier cadre, et une seconde partie d'étanchéité couplée au second cadre. Le second corps d'insertion tourne par rapport au premier corps d'insertion autour d'un arbre rotatif. Le premier corps d'insertion et le second corps d'insertion sont agencés de telle sorte qu'un espace est formé entre la première partie d'étanchéité et la seconde partie d'étanchéité. La première partie d'étanchéité et/ou la seconde partie d'étanchéité ont une lèvre ayant une forme annulaire autour de l'arbre rotatif. La lèvre a au moins une rainure sur sa surface dans la direction radiale vers l'extérieur.

    휠 베어링에 사용되는 밀봉 장치가 제공된다. 밀봉 장치는 휠 베어링에 삽입되며, 제1 삽입체와 제2 삽입체를 포함한다. 제1 삽입체는 환상의 제1 프레임과 제1 프레임에 결합된 제1 밀봉부를 갖는다. 제2 삽입체는 제1 프레임보다 작은 직경을 가지는 환상의 제2 프레임과 제2 프레임에 결합된 제2 밀봉부를 갖는다. 제2 삽입체는, 회전축을 중심으로 하여 제1 삽입체에 대해 상대 회전한다. 제1 삽입체와 제2 삽입체는 제1 밀봉부와 제2 밀봉부의 사이에 간극이 형성되도록 배치된다. 제1 밀봉부와 제2 밀봉부 중 적어도 하나는 회전축을 중심으로 하는 환상을 갖는 립을 갖는다. 립은 외측반경방향의 표면에 적어도 하나의 홈을 갖는다.
