    • 专利摘要:
    The mantle of the pressure roller with an adjustable bend, for paper manufacture, is supported at both ends by a swivel bearing at least, through the yoke (7). The hydraulic support mechanism within the roller mantle carries supporting forces from the yoke to the roller mantle. Both ends of the yoke have supporting surfaces resting on pedestals with the space between these surfaces along the vertical centre (m) being equal to or only marginally greater than the gap (I) between the bearings of the counter roller. The gap between the swivel bearings for the roller mantle is approximately equal to the space (I) between the counter roller bearings. A collar piece ranges from the pede pedestal within the roller mantle at each roller end for the yoke support surfaces. The design allows the bend to be applied at the ends of the roller, without increasing roller dimensions, so that the required pressures can be applied along the roller length. It also allows a drive to be fitted easily.

    专利说明:

    This invention relates to a design of a press roll with adjustable deflection, particularly used in paper industry.
    The purpose of the invention is to increase the effectiveness of the regulation of shaft bending.
    FIG. 1 shows a press shaft with adjustable deflection without a drive and with a self-aligning bearing positioned outside the casing; Fig. 2 is the same; the self-aligning bearing is located inside the skin xaj in Fig. 3, the same as in Fig. 2, driven, but without additional supporting devices; figure 4 is another design of figure 2,
    Preferably, the press roll with adjustable deflection for treating the fibrous material comprises a casing 2 mounted for rotation around a fixed core 1 for passing a web of paper in the gap with a control shaft 3, which can be rotated in supports 4, with the axis of rotation of the casing 2, the control shaft 3 and the gap between they lie in the plane of extrusion, the ends of the casing 2 are mounted by means of self-aligning bearings 5 in the supporting posts 6, the core 1 with its ends by means of supporting elements 7 is installed in The pillars 8a in the cavity 9 of the casing 2 are located the main hydraulic support device 10 mounted on the cylinder 2, connected with the discharge means 11 and in contact with the casing 2, the distance AB between the planes passing through the supporting elements 7 of the core 1, at least equal to or less than the distance between the supports 4 of the control 3, the distance between the self-aligning bearings 5 of the casing 2 is equal to the distance between the supports 4 of the control 3. Each support column 6 has a cantilevered tubular protrusion 12, through ohm of which the supporting elements 7 of the core 1 are mounted in the supporting posts 8, and the console protrusion 12 is located inside the casing 2.
    Longitudinal console ledge 12
    on its outer surface carries
    self-aligning bearing 5.
    The press shaft has at least
    At least one additional hydraulic support device 13, 14 mounted on the core 1 and located between the main hydraulic support device 10 and each end of the casing 2 and connected with the additional pressure means 15,16.
    Additional hydraulic support device 13,14 made in the form of pressure chambers having the shape of a semiring.
    The additional hydraulic support device 13, 14 is made in the form of pressure shoes.
    One of the ends of the casing 2 carries a toothed rim 17 for communication with the drive sprocket 18.
    The casing 2 has an elongation in the form of a sleeve 19 having the shape of a flange. The sleeve 19 through the self-aligning bearing 5 is connected with the support post 6, which simultaneously serves as the bearing housing. The inner cavity of the sleeve 19 is closed outside 20 with a lip seal.
    The supporting element 7 is spherical. A lip seal 21 serves to seal the gap between the core 1 and the support stand 6, which is mounted either on the movable support arm or on the base 22. The cavity 9 contains sealing gaskets 23 and the longitudinal gaskets 24. In the cavity 9, through the pressure means 11 is fed under pressure, the oil, as a result of which, the core I is acted upon by the supporting force directed toward the control shaft 3. The length of cavity 9 (pressure chamber) is only slightly less than the length of the sun of the pressing zone; outside this zone there is an auxiliary hydraulic support devices 13,14, driven by the injection of oil through additional injection means 15,16.
    One of the support devices 13 acts in the direction of the control 3, and the other 14 in the opposite direction, with the result that, if necessary, the ends of the core 1 can receive an additional bend. Position a denotes the median plane of the support 4 (bearing) of the control 3. Distance AB - distance to
    .Opposite support. The cover 20 has a lip seal 25.
    In Fig. 2, the self-aligning bearing 5 is mounted inside the casing 2, and the core 1 has hydrostatic pressure shoes 26 located in the pressing plane, which are supported by the outer surfaces on the casing 2.
    In FIG. 3, the spring ring 26 through the sleeve 27 does not allow the spherical support element 7 to move in the axial direction (rigid support). The support ring 28 and the spring ring 29 prevent the axial displacement of the bearing 5 relative to the support bar 6. The support ring 30 and the spring ring 31 prevent the gear rim 17 from displacing the bearing 5. The key 32, which is mounted on the support bar 6, enters the groove 33 of the core 1 and prevents it from turning.
    A drive shaft 34 with a prismatic key 35 is driven by a drive shaft (not shown). The shaft 34 is mounted in a spherical bearing 36, closed with a collar 37 with lip seal 38, Bearing 36 and a roof 37 are supported on shields 39 mounted on a support post 6. The shaft 34, through an angled gear coupling 40, drives the drive sprocket 18, which engages with the gear rim 17. The spherical bearing 41 facilitates rotation around the pin 42, which is rigidly connected to the support 6 Å through the flange 43 and the screw 44. if during operation the press roller casing 2 is flexed and accordingly tilts ring gear 17, the sprocket 18 without difficulty follows this inclination.
    The bearing 41 is axially supported on one side in the sprocket 18 by the spring ring 45, and on the other side by the ring 46 and the spring ring 47 is pressed against the pin 42. The support leg 6 is also a cover.
    The console protrusion 12 (figure 4) is extended inside the casing 2 by the amount
    I that allows the core 1 to be shortened accordingly.
    The press shaft functions as follows.
    46
    During operation, a sheet of paper (or a sheet of cardboard, textile cloth) passes through a gap formed by the casing 2 and the co-roll 3. In this case, the casing 2 of the shaft rotates in one direction, and the counter shaft 3 in the other.
    Pressure acting in the gap
    on the moving web, is determined by the oil pressure, which is located in the cavity 9 of the casing 2. At the same time, along the length of the air gap, i.e. in the direction perpendicular to the direction of movement of the web, uniform pressure distribution is achieved. I
    If necessary, an uneven pressure distribution can be obtained. This is achieved by the addition of support devices 13,14 due to a change in the bending moment.
