    • The invention relates to a device and a method for cooling a roll. The roll concerned can be a roller in a roll stand or a measuring roll. The device comprises a cooling shell having a cross section in the shape of a section of a circular arc, for covering a surface region of the roll (200), wherein, in the region of an edge of the cooling shell, a bearing is formed with a pivot joint (120) with an axis of rotation running perpendicular to the circular arc-shaped cross-section, for pivoting the cooling shell about the axis of rotation. According to the invention, in order to ensure that the size of the cooling gap during the rolling operation or during the operation of a measuring roll is always autonomously optimally set, the bearing has a degree of freedom in radial direction r with respect to the circular arc-shaped cross-section of the cooling shell, such that the cooling shell is mounted in the bearing in such a way as to be freely movable in the radial direction.
    • 本发明涉及一种用于冷却辊的装置和方法。 有关的卷筒可以是轧机机架或测量辊的轧辊。 该装置包括具有截面为圆弧形截面的冷却壳体,用于覆盖辊(200)的表面区域,其中,在冷却壳体的边缘的区域中形成轴承 具有垂直于所述圆弧形横截面延伸的旋转轴线的枢转接头(120),用于使所述冷却壳体围绕所述旋转轴线枢转。 根据本发明,为了确保在轧制操作期间或在测量辊的操作期间的冷却间隙的尺寸总是自主地最佳地设定,轴承在径向方向r上具有相对于圆形 所述冷却壳的弧形横截面使得所述冷却壳以可在径向上自由移动的方式安装在所述轴承中。

    • In order to increase the carrying capacity or rolling capacity of a roll assembly in a rolling mill, throttle elements are used, shutting off the lateral flow of the lubricating film in a partial region between the roll necks and the bearing surface of the roll neck mounting, and thereby bringing about an increase in the pressure on the lubricating film. In this case, at least one throttle element takes the form of an annular segment, in order to form an annular region for shutting off the lubricant in the annular gap. The invention makes it easily possible to retrofit existing installations without making structural modifications. In the case of new installations, the same carrying capacity as before can be provided while reducing the overall space required. The carrying capacity of the mounting can be flexibly adjusted according to the dimensioning of the shut-off region for the lubricant flow.
    • 为了增加轧机中的辊组件的承载能力或轧制能力,使用节流元件,其切断辊颈与轧辊颈部的轴承表面之间的部分区域中的润滑膜的横向流动 轴承组件,从而导致润滑膜中的压力增加。 至少一个节流元件被实施为环形段,形成用于环形间隙中的润滑剂的角关闭区域。 本发明使得现有装置可以容易地改装,而不需要进行结构修改。 在新安装的情况下,可以提供与之前相同的承载能力,同时减小安装空间的尺寸。 可以基于用于润滑剂流动的截止区域的尺寸来灵活地调节轴承组件的承载能力。
