    A roll with a revolving hollow roll and a stationary cross head which extends therethrough lengthwise, spaced a distance from the inside circumference of the hollow roll on all sides, has, in the space between the hollow roll and the cross head, a longitudinal chamber provided with a feed line for pressure liquid, divided by a sealing arrangement which comprises strip shaped longitudinal seals extending on both sides of the action plane of the roll, as well as transverse end seals. The transverse end seals are designed as gap seals, the gap surfaces of which are kept spaced from each other by separate precision antifriction bearings.

    专利说明:

    The invention relates to mechanical engineering and can be used in rollers for pressure treatment of material in the form of a web.
    The aim of the invention is to reduce friction losses and decrease wear on the end transverse roll seals with a higher pressure of the working fluid.
    FIG. 1 shows the swath; | In FIG. 2 is a section A-A in FIG. one; in fig. 3 — node 1 in FIG. 1, (an embodiment of a transverse seal in the form of a thrust precision rolling bearing), FIG. 4 is the same embodiment of the transverse seal in the form of a radial precision rolling bearing.
    The roller includes a fixed axis 1 and a cylinder 2 rotating around it, the inner surface of which from all sides is located at some distance from the outer surface of the middle part of the axis, and the bearings 3 installed near the ends rest on axis 1. Spurs 4. axis 1 protrudes from cylinder 2 and form roll axles through which forces can be transferred to the roller or with which the roller can be supported on the brackets for fastening it. Counter roll 5 is adjacent to the main roll from above and forms with its upper side (forming) the gap 6 between the rollers.
    The gap formed between the bearings 3 due to the gap between the inner cylinder cylinder 2 and the middle part of the t axis is divided
    35 Another slit surface 20 is provided on another ring 21 under the bolster, which consists of a radial flange 22 and a specially directed annular flange 23,
    adjacent to the inner surface 0 of cylinder 2, viewed on its outer edge 7 of cylinder 2, mounted on axis 1 diametrically opposed (i.e. in the widest place), as well as transverse end seals 9 mounted on the inner side of bearings 3 adjacent to them on the camera 10, lying on the side of the gap 6 between the rollers, and the camera 11, remote from the gap 6 between the rollers. Chamber 10 enters trunk 12, by means of which working fluid can be introduced into chamber 10. This working fluid, on the one hand, presses against the inner surface 7 of cylinder 2, and on the other hand, onto surface 13 13 facing it. Under the action the pressure in the chamber 10, which is necessary to obtain lipoposta ring 15, and the end face of the drill, facing the ring 15, forming a slit surface 20. The working surface 24 for rollers is formed 45 side surface of the radial flange 22, facing the shoulder 23
    The bearing ring 21 interacts with a stop (support) sleeve
    5 (j 25, made in the form of a hub with a flap, which is rigidly and firmly fitted onto the axle 1 from the inner side of the ring 21 and which carries axial, radial flange,
    The 55 knotted with the ring 21 pins prevent rotation of the bearing ring 21 relative to the axis 1. In order to ensure that the ring 21 fits to the roller 18 or to another ring 15, when
    The linear pressure, axis 1, can bend in the gap from all sides in relation to the inner surface of the zipindra, without touching it. This may entail a known deflection of cylinder 2, because it is supported through bearings 3 on axis 1..
    In the longitudinal seals 8, when the cylinder 2 rotates, there are always leaks in the lower chamber 11, so that it is gradually filled with a working fluid. In some cases it is desirable to fill also
    this chamber is forced by the working fluid under other pressure, which is in a certain relation to the pressure in chamber 10.
    The lateral end seal 9 (Fig. 3) includes a precision rolling bearing 14, designated as a single unit, in the form of a thrust roller bearing, the ring 15 of which is embodied in the form of a radial flange and with cylinder 2 rigid. connected. The radial flange 15 is on one side adjacent to the internal search 16 on the inner surface 7 of the hollow roll, and on the other side to the bearing 3. The bearing ring 15 has a flat surface 17 for the bearing rollers 18 and at the same time forms a slotted surface for the compaction slit 19 .
    Another slit surface 20 is provided on another bearing ring 21, which consists of a radial flange 22 and a specially directed annular collar 23, provided
    looked at its outer edge
    looked at its outer edge
    against the ring 15, with the end of the collar facing the ring 15 forming a slit surface 20. A working surface 24 for the rollers is formed. the lateral surface of the radial flange 22 facing the flange 23 ..
    The bearing ring 21 interacts with a locking (support) sleeve.
    25, made in the form of a hub with a flange, which is rigidly and firmly mounted on the axis 1 on the inner side of the ring 21 and in its radial flange carries axial, detachably connected with the ring 21 of the trunnion, preventing rotation of the bearing ring 21 relative to axis 1. To ensure fit rings 21 to rollers 18 or to another ring 15, when from
    In the absence of pressure in chamber 10, axially acting springs 2.6 are provided.
    The bearing ring 21 is mounted with respect to the hub of the support sleeve 25 with a radial clearance of 27, so that the hub of the support sleeve 25 can move somewhat relative to the ring 21. In this zone, a seal 29 is provided in the annular internal groove 28 of the radial flange 22. Fluids from chamber 10. This seal cannot rotate as parts 21 and 25 do not rotate relative to each other, but it must cope with slight relative displacements of parts 21 and 25 while maintaining the function y tightness. Actually, compaction during rotation occurs in the slit 19, in which the slot surfaces 17 and 20 rotate against each other. Since these slotted surfaces can be kept at a very small distance of 0.04-0.07 mtr, due to the throttle effect, a small amount of working fluid (FIG. 3) flows downwards along the slit 19, so that pressure can be suppressed in . Chamber 10 with a relatively small flow of working fluid. The escaping small amounts of liquid serve to lubricate the bearings 14 and 3. A special bead 23 and a slit 19 can be placed radially from the inner end surfaces of the rollers 1.8, but then the rollers 18 will be in the high pressure zone, which is undesirable.
    FIG. Figure 4 shows an alternative embodiment in which the lateral end seal 30 includes a precision radial roller bearing 31 containing an inner mounting ring 32 of a cylindrical outer surface 33 of which forms one slit top. ness The adjusting ring 32 is separated by a narrow slit 34 from axis 1 and, thus, can be shifted somewhat radially relative to it and also deviate somewhat. The rotation of the ring 32 is prevented by a pin 35 entering into the inner axial groove 36 of the ring 32. Sealing with respect to the working fluid in the chamber 10 is effected by an annular seal 37,

    The other ring 38 of the liner includes a radial flange 39, the surface on the inner circumference of which forms another slotted surface 40. An axial flange 41 is attached to the radial flange 39 on the outside, the surface 42 on the inner circumference of which forms another working surface for the rollers 18. Thanks to rollers 18 the slot surfaces 33 and 40 are kept at a small distance, which makes it possible to form a sealing gap 43, the rollers 18 are outside the high pressure zone.
