摘要： In a press roll apparatus, bearing portions rotatably support end portions on both sides of a pair of press roll portions, respectively. Each of the bearing portions includes a bearing body portion, a rolling bearing, and a pair of oil seal portions. The bearing body portion has an annular shape, and the press roll portion is inserted. The rolling bearing is positioned on the side of the press roll portion inserted into the bearing body portion as viewed from the bearing body portion, and rotatably supports the press roll portion. The rolling bearing is coated with lubricant. The oil seal portions are positioned on both sides in the first direction as viewed from the rolling bearing. The oil seal portions are connected to the bearing body portion. The oil seal portions are positioned so as to be spaced from the press roll portion inserted into the bearing body portion.

摘要： 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.

摘要： The invention relates to a roll arrangement for use in metallurgical technology, comprising a roll that has a roll barrel and two roll necks, and at least one neck bushing for accommodating at least one of the roll necks in a rotationally fixed manner. A carrier element that functions as a form-locking rotationally fixed connection is arranged between the roll neck and the neck bushing. In order to increase the load-bearing capacity of the roll bearing without increasing the size of or the mounting space for the roll bearing and at the same time ensure easy assembly, the roll neck is mounted in the neck bushing with some radial play such that a circumferential cavity is formed between the neck bushing and the roll neck in the unloaded stated as a result of the radial play. In order to increase the size of the cavity, the roll neck or the inner surface of the neck bushing additionally has a concave contour or profile.

摘要： The invention relates to a sealing device for installation in a roll arrangement between the roll journals of a roll and chock. The sealing device has an annular main body having sealing rims that extend radially outwards. Furthermore, the sealing device has an annular reinforcement element having a strip-like section which coaxially surrounds the main body on the outer side thereof. In order to ensure the dimensional stability and thus also the function of the sealing device even after the installation thereof in the roll arrangement, that is to say after said sealing device has been pushed onto the frustroconical roll journals, the reinforcement element according to the invention has, in addition to the coaxial strip-like section, at least one flange which is connected thereto and is connected to the sealing rim. Furthermore, the invention relates to said roll arrangement.

摘要： A device for recirculating oil from the end face of the barrel and the peripheral surface of the roll neck of rolling mill rolls. A sealing race arranged between the bearing elements and the end face of the barrel is mounted on the roll neck. A first conical ring body has a conical outer surface and a cylindrical inner surface that is seated on the outer surface of the sealing race and is sealed from the race, whereby inclination of the conical outer surface towards the end face runs towards the roll axis. A second conical ring body is rigidly mounted in the bearing housing and has a conical inner surface, which conical inner surface is arranged some distance opposite the conical surface of the first conical ring body, such that the two conical surfaces form a hydraulic pump gap that conveys oil away from the end face.

摘要： A C-section ring fixed on a steel-mill roll and coaxially surrounding its stub has inner and outer axially extending legs defining an axially open cavity. The inner leg is tapered away from the roll and is formed adjacent the free end with a radially outwardly open annular groove. An annular cover part fixed on a stationary support, engaged in the cavity, forming a drain compartment open axially away from the roll, and formed with a radially outwardly open catchment groove radially aligned with a free end of the inner leg is also formed with a passage extending from the catchment groove to the drain compartment. An annular extension on the cover part has an inner surface carrying a seal ring that bears radially inward on the stub. An add-on part on the extension forms with the extension, with the cover part, and with the C-section ring a labyrinth.

摘要： An inner seal ring is disclosed for use in an oil film bearing for a roll in a rolling mill. The roll has a neck with an intermediate section tapering from an end face to a reduced diameter end section contained within a sleeve. The sleeve is fixed in relation to the roll neck and is journalled for rotation in a bushing contained within a chock. A flexible neck seal is mounted on the intermediate section of the roll neck for rotation with the roll within a seal end plate fixed to the chock. The inner seal ring comprises a circular midsection with an annular face on one side and with inner and outer flanges projecting from an opposite side. The inner flange is configured to engage the neck seal, the outer flange is configured to coact in spaced relationship with the seal end plate to define a first labyrinth, and the annular face is contoured to coact in an abutting relationship with the roll end face in defining a second labyrinth.
