    • The invention concerns a rim J comprising two rim seats (11, 12) with different diameters, inclined outwards and axially extended outwards by two low projections (21, 22), the rim seat (11) with smaller diameter being axially assembled inwards to a support bearing surface (5) via a truncated portion (31) and the rim seat (12) with larger diameter being assembled axially inwards to said bearing surface (5) by a rib (6) of slight, even null, height, whereof the inner axial wall (60) has a generatrix forming with the axis of rotation an angle beta radially and axially opening outwards, not more than 30 DEG . The invention is characterised in that said rib (6), having an axially inner wall (60) with axial width L6 not greater than the axial width L12 of said second seat (12) is provided on the circumference with at least two small-size transverse grooves (7).
    • 本发明涉及一种边缘J,其包括具有不同直径的两个边缘座(11,12),其向外倾斜并通过两个低突起(21,22)向外延伸,具有较小直径的边缘座(11)向内轴向组装到 经由截头部分(31)和具有较大直径的边缘座(12)的支撑轴承表面(5)通过稍微甚至零零零的高度的肋(6)轴向向内组装到所述支承表面(5),其中 内轴向壁(60)具有母线,其旋转轴线成角度β径向和轴向向外开口,不大于30°。 本发明的特征在于,具有不大于所述第二座(12)的轴向宽度L12的轴向宽度L6的轴向内壁(60)的所述肋(6)在所述圆周上设置有至少两个小尺寸 横向槽(7)。
