    The invention relates to a connection arrangement between the ends of two rollers, one of which is designed as a shoe roll and a hose jacket, hereinafter also called short coat, and the other is formed as a counter roll to said shoe roll, wherein the connection arrangement at least one pair Connecting elements between the bearing housings of the shoe roll and the counter roll and means for attaching the connecting elements to the bearing housing of the shoe roll and the counter roll comprises.
    Under shoe roller here is a belonging to a shoe press, provided with a hose jacket press roll to understand, the shape of the counter roller corresponding stationary press shoe is pressed against the counter-roller to form a broad nip. The counter roll may consist of a deflection, full or hollow roll.
    The connection between two nip rolls has an important role to play in the loading of the rolls. The connection must withstand high load and should take up as little space as possible. A demanding application object is the connection arrangement between shoe roll and counter roll in the press section of paper machines.
    The prior art includes the C-clamp rails, with which the mutual attachment of the bearing housing of Nipwalzen done by C-shaped connecting elements. The fasteners require space in the transverse direction of the web-forming machine. In addition, especially with small rollers, the connecting elements do not fit between the bearing housings. The known technique also includes in the machine direction or transverse thereto arranged Zugstangen- or journal connections in which the tie rods open to the outside. In certain positions, the stiffening prevents the
    Fiber web machine opening. A tie rod solution is described in the published patent EP 1953295 Al. The problem with such solutions is that the aforementioned fasteners and tie rods are long and require space. When replacing the hose jacket of the shoe roll, the connecting elements or tie rods must be dismantled so that the change succeeds. This increases the costs associated with the shell change costs. Also, if the shoe roll is considerably smaller than the backing roll, there is a shortage in assembling the tie rods or fasteners to the shoe roll as a problem.
    The object of this invention is to provide a cheaper, easier and easier to use connection arrangement compared to the prior art. More specifically, it is characteristic of the connection arrangement according to the invention that the connecting elements are adapted to be pivoted, for the duration of the roll shell change, inside the contour described by the cross-section (i.e., base) of the shoe roll shell.
    This can be achieved by a connection arrangement between the ends of two rollers, one of which is formed as a shoe roll with hose jacket and the other is the counter roll to said shoe roll, said connecting assembly at least a pair of connecting elements between the bearing housings of the shoe roll and the backing roll and means for attaching the connecting elements to the shoe roll and the counter roll comprises. It is essential that the connecting elements are articulated by said means to the bearing housing of the shoe roll, that the connecting elements come to rest in their one position within the contour described by the tubular casing cross-section and thus allow the coat change. The
    Connecting elements then do not stand in the way of the jacket change, so that it is accelerated.
    Said means preferably comprise axes extending in the axial direction of the shoe roll for articulating the connecting elements to the bearing housing of the shoe roll and locking, i. Locking bolts for locking the connecting elements in the existing on the bearing housing of the backing roll locking holes. The joint axes allow easy pivoting of the connecting elements in jacket changing position inside the contour described by the cross section of the shoe roll shell.
    The connecting elements preferably have a jacket changing and a loading position, wherein in the load position, the connecting elements are aligned parallel to nip load or form a small angle with this, so that the connecting holes on / in the bearing housing of the smaller roller are closer to each other. Thanks to these positions, the jacket change can be done without dismantling the fasteners from the bearing housing of the shoe roll. The connection arrangement may comprise securing bolts for locking the connecting elements in jacket changing position.
    According to one embodiment, the connecting elements consist of tie rods. The tie rods are of simple construction and withstand high loads. There are / are at least a pair of connecting elements, but preferably two pairs of such elements or even a large pair of rolls of a wide machine even five pairs of such elements at the ends between the bearing housings of the shoe roll and the counter roll available. In this case, the load capacity of the connecting elements can be considerably increased when using large diameter rollers. The connection arrangement can also be ♦ ·· 4: ## · ···· »· · Locking means for locking the connecting elements in Mantelwechselstellung include.
    The diameter s of the counter roll can be 600-2000 mm, preferably 900-1600 mm. According to one embodiment, the counter-roller consists of a hollow cylinder.
    The diameter d of the shoe roll may be 600-2000 mm, preferably 950-1250 mm.
    Preferably, the connection arrangement is adapted for use between the bearing housings of a shoe and its counter-roller in fiber web machines, but can also be used for other corresponding purposes.
    With the connection arrangement according to the invention to achieve a very simple and compact connection that withstands high loads and requires less space in both the machine direction and in the cross-machine direction than the compounds of the prior art. It is particularly important that the replacement of the hose jacket of the shoe roll can be done without disassembly of the connecting elements of the connection assembly. As a result, the jacket change is considerably accelerated. The connection can be opened and closed without a complicated opening mechanism, and the opening of the connection does not require the least amount of machine direction or cross machine direction. In the case of plant renewal, thanks to the connection, new rolls can be installed without the need to change the old fiber-web machine frame. For example, a modern shoe roll can be installed in an old fiber web machine. The actuating mechanism of the connecting elements is very simple and thus also advantageous to manufacture. In general, the
    Manufacturers a shoe roll and for this match two mating rolls (one as reserve roll), so that he, the fasteners are hinged to the bearing housing of the shoe roll, now only needs to deliver a set of fasteners, which savings are achieved.
    In the following, the invention will be described in detail with reference to the accompanying drawings, which illustrate some embodiments of the invention. Show it:
    Fig. 1 considered the connection assembly according to the invention in the loading position in the direction of the roll axes; Fig. 2 considered the connection arrangement according to the invention in jacket changing position in the direction of the roll axes; FIG. 3 shows the connecting arrangement according to the invention in jacket changing position in the direction of the roll axes when replacing the hose jacket of the shoe roll; FIG.

    Fig. 1 shows a typical embodiment of the use of the connection arrangement according to the invention in an object in which the shoe roll has a considerably smaller diameter than the counter-roller. According to Fig. 1, the
    Connecting assembly 10 between the bearing housings 34 and 34 'of the shoe roll 12 and the backing roll 14 at least a pair of fasteners 18 and means 22 for attaching the connecting elements 18 to the bearing housing 34 and 34' of the shoe roll 12 and the backing roll 14. Both the shoe roll 12 and the mating roll 14 are with their axes / waves in the • ft • · • • • •
    l · l · · ft · ft · t · ft
    Bearing housings 34 and 34 'attached, of which at least one is fixedly mounted on a bearing block. The bearing block in turn is attached to the frame of the fiber web machine.
    The connecting elements 18 are preferably made of tie rods having holes 44 at both ends. Via the upper holes 46 and the lower holes 45, the connecting elements 18 are fixed to the shoe roll 12 and the counter roll 14, more precisely to the bearing housings 34 and 34 'of said rolls. The connecting elements 18 are articulated to the bearing housing 34 of the shoe roll 12 via axes 24 extending in the longitudinal direction of the shoe roll 12. The connecting elements 18 are thus arranged articulated in the machine direction. The articulation allows pivoting of the connecting elements 18 between the shell change position and the load position. The lower holes 45 of the connecting elements 18 serve for locking as well as the oval holes 28 on the bearing housing 34 'of the counter-roller 14, which are better shown in Fig. 3, 4a and 4b. The clearance of the connection can be realized through holes with play at least on the connecting elements or the bearing housings. For example, a slightly oval shaped hole is suitable for this purpose. In the load position shown in FIG. 1, securing pins 26 extending in the lower holes 45 of the connecting elements 18 as well as in the oval holes 28 in the axial direction of the shoe roll 12 are inserted, which lock the connecting arrangement 10. Between the axes 24 and the connecting elements 18, for example, a wedge connection can be arranged. For example, lubricated bronze bushings may be inserted into the holes, forming sliding pairs with the locking bolts.
    According to one embodiment, the connecting elements can also be articulated via the lower holes, wherein the
    Fasteners are moved down in jacket changing position down when the shoe roll is in sub-position. In this case, the securing bolts are inserted into the oval holes 28 and into the upper holes 46 in the loaded position.
    In load position, the connecting elements 18 are preferably aligned parallel to the nip load. The forces occurring under load are then easier to control than in the case in which the connecting elements 18 extend in an angle deviating from the Nipbelastungsrichtung. It is also a working embodiment particularly in connection with rolls of various sizes. The mutual distance of the hole centers on the same bearing housing is 500 - 900 mm. The vertical position also allows the use of relatively short connecting elements, so that relative to the solutions of the prior art relatively light fasteners can be made. The connecting element in the connection arrangement according to the invention is compact and preferably has a length of only 300-600 mm.
    In Fig. 2, the connecting elements 18 in
    Mantelwechselstellung so pivoted about the axes 24 that they come to rest within the contour described by the cross section of the hose jacket 16 of the shoe roll 12. In other words, the tie rods are arranged on the shoe roll 12 so that they can be pivoted to open into the interior of the bearing housing 34 of the shoe roll 12. The tie rods then remain within the contour described by the hose jacket 16, whereby a direct replacement of the shell 16 without disassembly of the connecting elements 18, simply by pulling the jacket 16 in the axial direction of the load axis 42 on the bearing housing 34 on the shoe roll 12 is made possible. The pivoting of the connecting elements in jacket changing position can be done mechanically by means of a pivot lever. This pivoting can be done either manually, but the connection arrangement can also have a separate mechanism for this. The manual pivoting can be done by pivoting the connecting elements 18 by means of a pivot lever arranged on the axis 24. With manual operation, an expensive hydraulic swing motor is unnecessary.
    Preferably, the connecting elements 18 can be locked by means of the securing means 50 in the OPEN position. These securing means 50 include locking holes 31 and locking bolts, which when locking the
    Connecting elements are inserted into jacket holes in the holes 31. Such locking holes 31 are preferably present on both connecting elements 18 and on the bearing housing 34 of the shoe roll 12.
    Fig. 3 shows the connecting arrangement in changing position, i. in the position in which the replacement of the hose jacket 16 takes place. To the bearing housing 34 'of the backing roll 14 are preferably guide wedges 36 for mutually guiding the bearing housings 34 and 34' during installation thereof. The fasteners 18 preferably have curled recesses for the fixed axis 42 of the shoe roll 12 to fit within the bearing housings 34 of the shoe roll 12. For larger rollers such recesses are not required, so that the connecting elements can also be straight.
    The connection arrangement according to the invention is, for example, for use in conjunction with a hollow roller as counter-roller. 9
    suitable. As a hollow roller, for example, the known under the product name SolidL hollow cylinder Metso comes into question. The diameter s of the counter roll may be 600-2000 mm, but preferably 900-1600 mm. As Schuhwal2e comes, for example, the well-known under the product name SymBelt shoe roll Metso in question. The diameter d of the shoe roll may be 600-2000 mm, but preferably 950-1250 mm. In the embodiments shown in Figs. 1-3, the upper roll consists of a fixed axle and hydraulic shoe load system equipped roll to be loaded and the lower roll of a hollow roller provided with roller bearings. When using the connection assembly according to the invention, the size of the bearing assembly is irrelevant, because the compound claimed on / in the bearing housing of the backing roll no place, apart from the connection hole locations on the inside. In general, the counter roller roller bearing is selected to be as large as possible in view of the load consumption.
    In the connection arrangement, the shoe roll and the counter roll may also be positioned in reverse, i. the shoe roll is at the bottom, the counter roll at the top. The positioning is determined by the trajectory in the fiber web machine. Preferably, however, the heavier roll is placed below. Although in the drawings, the illustrated connection arrangement only forms the connection of the bearing housings of the rollers on the one end face, however, the construction of the connection is preferably the same at both ends of the rollers. From the point of view of production, it is particularly advantageous that the connecting elements are hinged to the shoe roll, because in general the manufacturer, if it is a shoe press nip, a shoe roll and two counter-rollers, one of the latter as a reserve, would be the connecting elements 10th ··· «·« «* *« «· *

    The tie rods preferably to be used as connecting elements according to FIG. 4a can be 100 mm wide in the axial direction of the rolls and then withstand great loads. At high load two pairs of connecting elements can be arranged at both ends of the rollers, in which case, as for example in Fig. 4b, two connecting elements are arranged parallel to each other. The mutually parallel connecting elements together form, for example, a 200 mm wide entirety, which withstands a considerably greater load than the individual connecting element.
    The connection assembly is adapted for use between the bearing housings of fibrous web rolls. An advantageous embodiment is the connection between a shoe roll and its mating roll in the press section of a paper machine. Also for other corresponding applications, this connection arrangement is suitable. For the connection arrangement high-strength materials must be used so that a sufficient load capacity is ensured during operation. The fasteners and the securing bolts may be made, for example, of stainless steel suitable for this purpose which does not rust on the joint surfaces.
