    A stone roll for paper machines having a rotatable tubular roll shell of stone. A bearing flange is disposed at either end of the stone roll. A plurality of paraxially arranged stressing rods are disposed in bores in the roll and extend between the bearing flanges. A stationary beam extends through the bore of the roll. A layer of metal is disposed at or defined on the inner surface of the tubular roll shell. Seals extend from the sides of the beam into contact with the metal layer. A hydraulic pressure chamber is defined between the stationary beam and the inner surface of the metal layer and around the beam between the seals for enabling force exerted on the exterior of the roll to be transmitted to the stationary beam.

    专利说明:

    The invention relates to a roller for transmitting a pressing force to a web of fibrous material, mainly to a paper web, and can be used mainly in the pulp and paper industry.
    The purpose of the invention is to maintain the specified conditions of pressing due to reliable contact of the roll with the pressed sheet.
    FIG. Figure 1 shows a roller for transferring the pressing force to the web, a longitudinal section; in fig. 2 - a variant of the design of the roll, a longitudinal section .30
    The roller contains a tubular rotary body 1, through which the stationary core 2 passes, fixed by ends in support tool 3. Between the roller case and the core there is an annular chamber 4 in which elements of a hydraulic device are placed to transfer the pressing force from the roller body to the core. Chamber 4 may be 40 divided by the rod seals 5 into two half-ring-shaped chambers. A pressure fluid may be introduced into one of the chambers to transfer the pressing force from the housing 1 of the roll 45 to the core 2. Atmospheric pressure is preferably maintained in the other chamber. The longitudinal seals 5 are supported on the core 2, are capable of radial movement on it and are pressed against the cylindrical inner surface 6 of the roll body.
    Instead of a compression-shaped chamber 4, bounded by circumferential seals 7 and longitudinal seals 5, other elements may also be provided for transmission - | press effort. For example, it might be located sliding on

    The surface of the roll housing and the slip pad passing along its entire length. In this case, the latter would rest on the hydraulic chamber 4 of compression.
    In addition, there are several sliding elements arranged in a row that look like a plunger; each of these elements would have support on a hydraulic camera and slide along the inner surface of a rotating roll body.
    According to FIG. 2) to each end of the roll, the middle of the rolling bearing 8 lies in the same plane as the middle of the spherical sleeve 9. Instead, the rolling bearings 8 could also be located a short distance from the roll body and, for example, lean directly on the core in its part ten.
    According to FIG. 1 both support flanges 11 and 12 are clamped by means of the clamping rods 13 to the roll body, the outer surface of which is formed by a layer of natural or artificial stone-like material. There are several evenly distributed around the circumference of the clamping rods 13, each of which. located in its own, passing through the roll casing, hole, i.e. passes from one of its support flange to another and is connected to a layer of stone-like material. The diameter of each hole should be slightly larger than the outer diameter of the clamping rods. The annular gap present in each hole is thus filled with a becoming solid material. Due to this, vibration of the clamping rods is avoided and corrosion is prevented.
    FIG. Figure 1 shows that the longitudinal sealing strips 5 slide either directly on the inner surface 6 of the stone roll housing or on the metal layer deposited by electroplating. Instead of a metal layer, the surface 6 can also be formed by a synthetic layer.
    The stone roll housing in FIG. 2 compared to FIG. 1 has enlarged outer and inner diameters. Accordingly, the outer diameter of the supporting flanges 11 12 is also increased. In this case, the clamping rods 13 extend along the inner surface of the stone roll body at a small distance from it. Directly radially with respect to the clamping rods 1.3, a metal pipe 14 passes concentrically through the inside of the roll. At each end of the pipe 14, a support ring 15 or 16 is fixed, respectively. With these support rings, pipe 14 is centered on links 17 and 18, which are molded to the inside of support flanges 11 and 12. Each centering pair is sealed by means of a sealing ring 7. Thus, between the cylindrical inner surface of the stone roll body and the metal pipe 14 there is a closed annular inner space in the form of an intermediate chamber, which is filled first with liquid and then becoming solid filler 19.
    FIG. 2, the cylindrical inner surface 20 of the coarse 14 forms a working surface for the longitudinal seals 10. The circumferential seals 7 slide along the inner face sides of both bearing rings 15 and 16. The transfer of the pressing force from the stone roll body to the core 2 is not only through the compression chamber 4 and additionally through the filler 19 and through the pipe 14. It is essential that a filling material is used which completely fills all the areas of the intermediate space between the roll body and the pipe 14, i.e. the filler should not shrink when cured. In addition, it should not become brittle after prolonged use.
