Definitions
- the invention relates to a device for the axial displacement of rolls in the stand of a rolling mill, in particular the work rolls of a hot or cold rolling mill, the rolls being mounted in radial bearings at their ends, which are preferably designed as bearing journals, and are additionally provided with an axial bearing at one end, via which a displacement system, preferably a hydraulic pressure system, engages the roller.
- a displacement system preferably a hydraulic pressure system
- the object of the invention is to provide a device for the axial displacement of rollers in a stand of a rolling mill, which is free from these known disadvantages mentioned above and is particularly characterized by its very simple construction.
- the inner bearing ring of the radial bearing which is designed as a roller bearing and is attached to the bearing journal of the roller, is axially movable relative to the outer bearing ring of the radial bearing or vice versa. Any known displacement systems can advantageously be used.
- the inner bearing ring of the roller bearing designed as a rolling bearing according to the invention is axially movable relative to the outer bearing ring, practically no sliding friction occurs when the roller is axially displaced, since the axial movement of the inner bearing ring relative to the outer bearing ring of the roller bearing journal of the roller the bearing bodies located between the bearing rings is compensated for by their rolling movements.
- the roller is axially displaced, there is at most a slight bearing roller friction in the radial bearings of the roller, the overcoming of which, however, hardly requires any significant axial forces.
- the axial forces to be applied by the displacement system for the axial displacement of the roller can therefore be kept lower and lower than in the roller displacement devices known to date thereby saving energy and costs.
- the shifting system is integrated as a hydraulic pressure system in the axial bearing, whereby a roll shifting system that is simple in construction, particularly compact and closed to the outside is presented, which is not only more easily accessible and easier to maintain than the previously known roll shifting devices, but also compared to them dynamically faster and more reliable in its functionality.
- the hydraulic pressure system integrated in the axial bearing consists of a double-acting piston-cylinder unit, the outer bearing ring of the axial bearing being designed as a piston and the bearing housing surrounding it being designed as a cylinder.
- the outer bearing ring designed as a piston and the bearing housing of the axial bearing designed as a cylinder are made in several parts. In this way, maintenance and replacement of the bearing or the hydraulic pressure system or parts thereof considerably relieved.
- the radial bearings are, according to a further advantageous embodiment of the invention, with several, in rows in the axial direction at a distance bearing bodies arranged from each other. It is also particularly expedient here to use cylindrical roller bearings or radial bearings designed as needle roller bearings.
- the drawing shows a section of a roller (1) of a rolling mill with a bearing journal (2) which is tapered in a step-like manner at the left end and is mounted in a radial bearing (3) and an axial bearing (4) shown in longitudinal section.
- the right end of the roller (1) which is not shown in the drawing, is provided with a single-stage bearing journal which is mounted in a radial bearing which is of the same design as the radial bearing (3).
- These radial bearings (3) consist of an inner, relatively long, attached to the bearing journal (2) trained bearing ring (5) and two outer bearing rings (7, 8) arranged in the stand (6) of the rolling mill and from the intermediate bearing bodies (9) arranged in four rows at a distance from one another.
- This inventive design of the radial bearing (3) very advantageously allows an axial displacement (arrows 10) of the roller (1) together with the inner bearing ring (5) relative to the outer, two-part bearing ring (7, 8) without it to the undesirably disadvantageous, energy-consuming sliding friction between the bearing rings (5) and (7, 8), since the axial movement of the inner bearing ring (5) relative to the outer bearing ring (7, 8) is absorbed by the bearing bodies (9) and into one Rolling motion is converted from very little friction.
- the radial bearings (3) are expediently designed as cylindrical roller bearings in order to be able to reliably absorb and compensate for the high loads occurring on the rollers during operation of the rolling mill.
- other roller bearings such as needle roller bearings, barrel roller bearings, etc. in a single or multi-row arrangement can also advantageously be used as radial bearings.
- the axial bearing (4) with integrated hydraulic bearing which is also shown in the drawing in longitudinal section and is arranged on the left-hand side and is firmly connected to the stepped bearing journal (2) Printing system provided.
- This axial bearing (4) consists of an inner bearing ring (11) attached to the bearing journal (2), which counteracts axial displacement on the journal (2) is secured by support and retaining rings (12, 13, 14, 15), and from an outer bearing ring (16) with intermediate support rings (17) and bearing rollers (18).
- the outer bearing roller support ring (17) is supported in the axial direction by a ring (19) with a flange which is firmly connected to the outer bearing ring (16).
- the outer bearing ring (16) of the axial bearing (4) is provided on the outside with an annular extension (20) with a sealing ring (21) which is guided in an axially movable manner in a cylindrical recess (22) of the bearing housing (23).
- annular disc (24) with a sealing ring (25) is attached, which seals the cylindrical recess (22) in the bearing housing (23) to the outside in a pressure-tight manner.
- the axial displacement path of the roller (1) which in practice lies between approximately 0 and 400 mm, can be easily monitored and adjusted and / or adjusted at any time even during the rolling operation.
- the bearing housing (23) is sealed off from the outside by an end cover (35) and there is a rubber between the roller body (1) and the roll stand (6) -elastic cuff (36) arranged.
- the device designed according to the invention can be used not only very advantageously for the axial displacement of work rolls and backup rolls in the stand of a hot or cold rolling mill, but also in rolling mills, for. B. for crushing hard materials or the like.
- the device according to the invention is particularly characterized by its very simple and compact, after closed, easily accessible, easy to assemble or disassemble and easy to maintain design that can be retrofitted to existing rolling mills at any time.
- the roller displacement device according to the invention can be used very advantageously in duo, four-high, six-high and special rolling mills.
- the measures according to the invention are not limited to the exemplary embodiment shown in the drawing figure.
- the radial bearings can have any shape, for example a plurality of radial bearings can also lie one above the other.
- the respective structural design is left to the person skilled in the art to adapt to the specific use.
