    摘要: An oil feed system for a variable-crown roll which includes a stationary roll axle, a roll mantle arranged revolvingly on the roll axle and hydraulic loading elements acting upon an inner face of the roll mantle in a radial direction and supporting the roll mantle on the roll axle. The loading elements function to regulate the axial profile of the roll mantle. In the roll axle, an axial through hole is formed which communicates with cylinder bores in which the hydraulic loading elements are arranged through substantially radial bores or equivalent ducts. In the axial through hole, at least through one of the roll ends, oil feed pipes are installed and through which pipes, a pressure fluid is fed to the hydraulic loading elements. Into the axial through hole in the roll axle, at the location of the loading elements, an intermediate flange is installed, which operates as a distributor piece and is connected with the loading element. One of the oil feed pipes passes to each of the distributor pieces to which each loading element is connected so that, through the distributor piece, the pressure fluid can be passed to the loading element whereby the loading produced by means of the loading element is adjustable in the desired way.

    摘要: The invention relates to a method for providing a roll (1) for a paper machine with sliding bearings, the roll comprising a stationary roll axle (3) and a tubular roll mantle (2) arranged to revolve around it. In the method, the roll mantle (2) is supported on the roll axle (3) by means of hydraulic sliding bearing members (4a, 4b, 5a, 5b; 25, 28; 40a, 40b) which are arranged to accomplish radial fitting with bearings of the roll mantle in the loading direction and in the lateral direction with respect to it, and the axial fitting with bearings of the roll mantle. The sliding bearing members are loaded by means of a hydraulic medium, the feed of which to the sliding bearing members is controlled by means of control valves (6; 30; 40). In the method relating to the invention, when loading (F) is applied to the sliding bearing member (4a, 4b) effective in the loading direction, the loading force applied to the sliding bearing member (4a, 4b) subject to an external load due to the loading is compensated for automatically, essentially immediately, without an external control instruction, by means of the movement of the control valve (6) stem (60) of the sliding bearing member (4a, 4b) subject to loading, the said control valve (6) bringing about a rapid increase in the pressure of the hydraulic medium in the sliding bearing member (4a, 4b) subject to the external load, at the same time as the pressure of the medium supplied to the sliding bearing member (5a, 5b) located radially on the opposite side of the roll axle (3) in the loading direction is adjusted to a certain minimum value, whereby the bearings of the roll mantle are rendered so as to be essentially without stroke. The invention also relates to a roll for a paper machine which is provided with sliding bearings.

    摘要: A method for fitting a roll mantle of a tubular roll used in a paper machine or equivalent with glide bearings and a tubular roll. The roll mantle is supported on a stationary roll axle by hydraulic glide bearing elements acting upon the roll mantle and/or upon the roll ends. The bearing elements are loaded hydraulically by the pressure of a first pressure medium. The roll is loaded from outside radially in the direction of at least one plane, i.e. in a so-called principal loading direction. The roll mantle is supported on the roll axle by the glide bearing elements which act radially substantially in the principal loading direction in opposite directions and which are provided with a device for regulating the braking pressure provided by a second pressure medium, so that in the principal loading direction, the roll mantle is allowed to move over a certain distance. When the roll mantle approaches its preset extreme position in that direction, the movement of the roll mantle is braked and slowed down by the regulation device, and finally the movement is stopped in its extreme position by the glide bearing elements.

    摘要: A variable-crown roll including a stationary roll axle, a tubular roll mantle rotatably mounted by its ends on the roll axle by end bearings and hydraulic loading shoes arranged between the roll mantle and the roll axle. The loading shoes act upon an inner face of the roll mantle in a direction toward a nip defined in part by the roll, are supported on the roll axle and are loaded by a hydraulic pressure medium. The nip pressure is profiled in the axial direction of the roll by regulating the pressure of the pressure medium passed into the loading shoes. The roll mantle is made of a fiber-reinforced composite material so that the stability of shape of the roll mantle in the direction of the circumference is good, i.e., it maintains its shape, and the rigidity in the axial direction is low, i.e., it is profitable.

    摘要: A bearing control system for a roll with hydrostatic bearings which is mounted by its axle on a bearing block or other equivalent frame member by hydraulically loaded hydrostatic bearing elements. A principal bearing element acts in a principal loading direction and another bearing element is a backup bearing element which acts in a direction opposite to the principal loading direction. The bearing elements include bearing shoes positioned freely around the axle in order to support the axle so that the roll revolves freely in relation to the bearing block or other frame member. The control system feeds a hydraulic pressure medium to the hydrostatic bearing elements so that the roll is displaceable in the principal loading direction, e.g., in the direction of the nip plane, by displacing the axle via the bearing elements.

    摘要: A method for providing a tubular roll mantle of a roll for a paper machine or equivalent with glide bearings and a roll including glide-bearings. The roll mantle is supported on a stationary roll axle by hydraulic glide-bearing members acting upon the roll mantle or upon the roll ends. The bearing members are loaded hydraulically by a pressure medium. The roll mantle is supported on the roll axle by at least one pair of glide-bearing members which acting radially and/or axially in opposite directions. When an outside force that shifts or attempts to shift the roll mantle in the direction transverse to the main loading direction and/or in the axial direction is applied to the roll mantle, the pressure in the glide-bearing member placed at the side of the higher loading is adjusted to a level higher than the pressure in the glide-bearing member acting in the opposite direction so that the outside forces are neutralized. In another embodiment, the roll mantle is permitted to be shifted over a certain distance in the main loading direction. When the roll mantle approaches its preset extreme position in this direction, the movement of the roll mantle is brake down, and finally the movement is stopped in its extreme position by the glide-bearing members.

    摘要: A method and arrangement for computing and regulating distribution of linear load in a multi-nip calender. A material web is passed through the nips in a set of rolls including a variable-crown upper roll, a variable-crown lower roll and intermediate rolls positioned between the upper and lower rolls. The rolls in the set of rolls are supported so that, when the nips are closed, the bending lines of the rolls are curved downwards. When computing and regulating the linear loads, one or more of the physical properties affecting the bending of each intermediate roll under load, such as bending rigidity, mass, shape, and material properties, are taken into account. The ratio of the linear loads applied to the intermediate rolls, the weight of the rolls per se, and/or the support forces applied to the rolls are regulated so that the set of rolls is in a state of equilibrium and a predetermined state of deflection.
