Abstract: A seal (100) for sealing a lubricant space prevents lubricant (320) escaping. A rolling stand has a seal of this kind. The seal (100) is made at least partially from elastic material. To enable a pressing force FR, with which the bottom face (112) of the seal is pressed against an opposite contact surface (218), for example of a roll journal (212), to be variably set, the seal (100) has at least two cavities, which are separated from each other in the circumferential direction and which are open towards the lubricant space of the bearing.

Abstract: A roll stand for the rolling of rolling stock, especially metal products. The roll stand includes at least two chocks for mounting at least one roll, the roll being rotatably mounted in the chocks by its two cylindrical roll necks. A cylindrical neck bushing is arranged on the roll neck with radial play. A rotationally fixed annual axial bearing is axially offset from the neck bushing. The bearing arrangement for the roll necks in the chocks is formed as a plain bearing, preferably a hydrodynamic oil film bearing. When subjected to a load in a rolling process, the neck bushing moves and deforms not only in the radial direction, but also in the axial direction.

Abstract: 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.

Abstract: A device for measuring a wear condition on the plain bearing surface of a sensor plate comprises a measuring apparatus, which has wear sensors of a sensor plate integrated into the plain bearing surface. To capture the material removal at the plain bearing surface due to wear an evaluation apparatus is in signal connection with the wear sensors. The evaluation apparatus is designed, with respect to programming, in such a way that a change, in particular an increase, in the ohmic resistance value of the electrical conductor of a certain wear sensor can be captured in dependence on its own material removal, in order to thereby ensure that the amount of the material removal at the plain bearing surface and/or the remaining thickness of the plain bearing surface at the location of said certain wear sensor can be inferred from the detected change in the resistance value.

Abstract: A volume flow regulating valve for controlling the volume flow of a fluid medium in two outflow ducts. The volume flow regulating valve is composed of a cylinder with a dual piston mounted axially displaceably in the cylinder, with a central pressure chamber being formed in the region of the barbell-shaped central piece of the dual piston. Aside from an inlet for the fluid medium, it is also the case that the two outlet ducts are provided at the central pressure chamber. The outlet ducts are arranged on the cylinder with such an axial spacing that—when the dual piston is situated in a central position in relation to the two outlet ducts—the first outlet duct—preferably partially covered by the first piston—and the second outlet duct—preferably partially covered by the second piston—each open up an equal opening cross-sectional area.

Abstract: A method and a device for controlling a parameter, for example the profile or the flatness, of a rolled stock in strip form. A cooling jacket that can be brought up to the roll and is designed to be variable in its effective length b in the circumferential direction of the roll is used as a final controlling element.

Abstract: To increase the load-carrying capacity or rolling capacity of a roll assembly in a rolling mill, throttle elements are used, which shut off the lateral flow of the lubricating film in a partial region between the roll neck and the bearing surface of the roll neck bearing assembly, thereby bringing about an increase in pressure in the lubricating film. At least one throttle element is embodied as an annular segment, forming an angular shut-off region for the lubricant in the annular gap. The invention makes it possible for existing installations to be easily retrofitted, without the need for structural modifications. In the case of new installations, the same load-carrying capacity as before can be provided while the dimensions of the installation space are reduced. The load-carrying capacity of the bearing assembly can be flexibly adjusted based on the dimensions of the shut-off region for the flow of lubricant.

Abstract: The invention relates to a rolling stand for the rolling of metallic rolling stock. The rolling is achieved with the aid of a roll of which the two roll journals (112) are rotatably mounted in recesses (122) of chocks (120). The recesses are supplied with coolant and/or lubricant via a high-pressure inlet (124) and at least one low-pressure inlet (126). The high-pressure inlet is fed via high-pressure conduits (132) from a high-pressure pump (130). To reduce the costs for driving the high-pressure pump in relation to the prior art, the invention provides that the high-pressure pump is rotationally coupled to the roll journal via a gear mechanism in order to be driven thereby.

Abstract: An installation piece for supporting a roller in a roller stand of a roller frame. The installation piece includes a main bore for receiving a journal of the roller, an inlet for a lubricant, an outlet for the lubricant, and a pump device for pumping the lubricant leaving the installation piece through the outlet. The pump device has a housing, an inlet channel, and an outlet channel. The inlet channel communicates with the inlet and the outlet channel communicates with the outlet for the flow of the lubricant. The pump device is driven by the flow of the lubricant in the inlet. The housing of the pump device is equipped with a screw pump and a turbine, which is driven by the pressurized inflowing lubricant, in the inlet channel for driving the screw pump.
