摘要： A roll with a revolving hollow cylinder which forms the working roll circumference, and a stationary crosshead penetrating said hollow cylinder lengthwise and leaving clearance all around to the inner circumference of the hollow cylinder in which the hollow cylinder can shift radially as a whole, e.g., can drop under its own weight on to the top side of the crosshead. A damping element is provided to damp this sinking movement before contact is made. It features a piston which plunges into a cylinder filled with hydraulic fluid and initially open to the top. During the plunging action, the hydraulic fluid is displaced out of the cylinder and flows away, in a throttled state, between the piston and the cylinder and/or through especially provided choke bores, so that the damping effect is attained.

摘要： A hydrostatically supported roll has several hydrostatic support elements supporting the inner circumference of a rotating hollow roll. The hydrostatic elements are supported on the stationary crosshead that extends through the rotating roll to form a clearance space therewith. Each hydrostatic element has support pockets supplied with a first pressurized fluid via choke canals and branch lines connected to a flow-controlled pump delivering a constant volume of first pressurized liquid, regardless of the counterpressure in the support pockets. The first pressurized liquid fed to the support pockets is temperature-controlled. The support pockets are separated from essentially closed pressure chambers, which are supplied with a second pressure-controlled pressurized liquid from separate feedlines for pressing the hydrostatic elements against the inner circumference of the hollow roll to support same. The second pressurized liquid is not communicated to the inner circumference of the hollow roll. Therefore, independent of any pressure change in the pressure chambers, the same quantity of first pressurized liquid passes over the edges of the support pockets to ensure that the amount of heat transferred to the inner circumference of the hollow roll remains constant.

摘要翻译： 静压支撑辊具有支撑旋转中空辊的内圆周的多个静液压支撑元件。 静液压元件支撑在固定十字头上，该十字头延伸穿过旋转辊与其形成间隙空间。 每个静液压元件具有通过扼流管和连接到流量控制的泵的第一加压流体提供的支撑袋，其输送恒定体积的第一加压液体，而不管支撑袋中的反压力如何。 供给到支撑袋的第一加压液体是温度控制的。 支撑袋与基本上闭合的压力室分离，其从单独的进料线供应第二压力控制的加压液体，用于将静压元件压靠在中空辊的内周上以支撑其。 第二加压液体不与中空辊的内周连通。 因此，独立于压力室中的任何压力变化，相同量的第一加压液体通过支撑袋的边缘，以确保传递到中空辊的内周的热量保持恒定。
