Definitions

  • the invention relates to a multi-part roller with a hollow cylindrical, axially secured bale, which is connected at its ends in a form-fitting manner with a trunnion, which may optionally engage with a flange in corresponding recesses on the associated end of the bale, the aligned longitudinal axes of which define the axis of rotation of the roller.
  • Such rollers are generally symmetrical.
  • the center forms the bale, which can be smooth or calibrated.
  • At both ends of the bale there are trunnions with which the roller is mounted in its bearings.
  • Dome pins are arranged on both sides of the trunnions, via which the rollers are driven.
  • the roll barrel can also be asymmetrically calibrated and shaped as a vocational roll.
  • rollers are in one piece. Since, in general, the bale or the middle section wear out faster than the other roller parts, that is, the trunnions and the drive pins, it is necessary to replace the entire roller with a new one as soon as the middle section or bale is worn out; this means that the trunnions and the drive pins also have to be replaced, although it would not be necessary to replace these parts as such.
  • connection can basically be made by shrinking, welding, screwing and the like.
  • shrinking roller bodies or roller sleeves onto one-piece axles a shrink fit with an exact fit is required.
  • the roll bodies or roll shells are shrunk onto the axles, it is difficult to loosen the shrink connection again.
  • a shrink connection can only be loosened frequently. furthermore, not all desired material combinations are possible.
  • roller bodies A prerequisite for connecting roller bodies to axes by welding is that the materials to be connected are weldable.
  • the roller body is practically no longer detachable from the axis and, consequently, the entire roller is a unit that can no longer be separated.
  • FR-A-1 562 660 and FR-A-2148609 have disclosed multi-part rollers which allow simple changing of the roller barrel alone.
  • the roller according to FR-A-1 562660 has an axis with pins tapering at both ends.
  • the hollow roller bale rests on the straight middle part of the axle and is enclosed by bearing internals that are located on the conical axle ends.
  • the bearing internals can be removed and pulled off hydrostatically by means of pressure oil introduced between the bearing bush and the journal, whereby the roll barrel is exposed.
  • the roller according to FR-A-2148 609 has a continuously tapering axis with trunnions forming bushes on both ends, which are adapted to the conical shape of the axis, and a central bushing for receiving the roller barrel.
  • the individual parts of the roller are firmly but releasably clamped together on the common axis of rotation by means of an axial frictional connection, for which purpose wedges and screws are used, one of which works with conical stones between a trunnion and the roller barrel perpendicularly through the axis of the screw.
  • the axial preload can be varied depending on the wedge suit.
  • the torque in the roller bales is transmitted exclusively by means of a frictional connection.
  • the invention has for its object to provide a multi-part roller with the features of the preamble of the main claim, which is not only easy and inexpensive to manufacture, but which guarantees a perfect operating behavior with non-positive and positive, reliable connection and nevertheless a light and if necessary allows quick replacement of the roll barrel.
  • This object is achieved according to the invention by an eccentric connection between the trunnion and the bale.
  • This allows a multi-part roller to be realized, the individual parts of which are connected to one another by a sensible combination of positive and positive locking using simple means and which is suitable for transferring high rolling loads for a wide variety of roller types with great economy.
  • the selected non-axial assignment ensures a secure positive connection between the axle section and the roll barrel, whereby the positive connection is able to continue to transmit the torque after the clamping force generated by the tensioning screw has been exceeded without damaging influence on the rolling operation, in the event of such overload peaks caused by the rolling force with increased torques, the positive connection alone takes over the introduction of the excess torque into the roll barrel.
  • At least one flange which is eccentric to the common axis of rotation engages in a form-fitting manner in a correspondingly eccentric recess at one end of the bale.
  • At least one trunnion has an axis that continues at least partially in the bale coaxially to the common axis of rotation, following the flange, and the axial securing of the trunnion takes place between the axis of the one trunnion and the immediately other trunnion or between the two axes of the Trunnion.
  • the resultant advantage consists in particular in that the axle is connected in one piece to the trunnion and is pulled through the bale.
  • the connection point between the two trunnions is outside the bale, which facilitates the assembly and disassembly of the roller and is advantageous for the use of the roller in operation.
  • the axis is guided concentrically through the bale, so that the material of the bale is largely evenly distributed around the axis, which has advantages in particular when designing such a roller as a pilgrim roller.
  • the axis which continues coaxially to the common axis of rotation, enables the torque to be introduced into the bale exclusively via the eccentric flanges. This arrangement is advantageous for a bale that is symmetrical about its axis of rotation.
  • the position of the threaded or tensioning screw causing the axial preload excludes additional shear stresses when transmitting the torque.
  • the axis is advantageously mounted eccentrically to the common axis of rotation.
  • This eccentric axis guide in asymmetrical caliber cross-section i.e. In the center of the caliber, the central connecting axis and the eccentric arrangement of the flanges on the trunnion ensure easy introduction and transmission of the drive torque, as well as the mentioned advantage with regard to even caliber material distribution around the axis.
  • asymmetrical axis guidance it is not absolutely necessary that the flanges are provided eccentrically, since the asymmetrical axis guidance alone ensures good introduction and transmission of the drive torque.
  • the screw bolt coaxially to the axis and the trunnion.
  • eccentric axis guidance it is possible to arrange the screw bolt either coaxially to the trunnion and eccentrically to the axis or coaxially to the axis and eccentrically to the axis of rotation of the trunnion.
  • the roller is held together non-positively by the threaded bolt with right-hand and left-hand thread. Furthermore, this enables simple assembly and disassembly of the roller.
  • the threaded bolt carries separate right-hand and left-hand threads, namely right-hand threads at one end and left-hand threads at its other end.
  • the threaded bolt can also be designed such that it carries continuous superimposed right and left-hand threads, in such a way that a continuous right-hand thread is also superimposed on a continuous left-hand thread or vice versa.
  • a further right-hand and left-hand thread can be provided for tensioning and releasing the roller parts.
  • This additional right and left hand thread is expediently designed as a superimposed right and left hand thread.
  • Two nuts can be screwed onto the additional right-hand and left-hand thread, one of which can be provided with a right-hand thread and the other with a left-hand thread or vice versa.
  • the associated nuts are expediently given the same thread pitch and depth as the threads of the threaded bolt, but in right-handed and left-handed versions. Furthermore, the two nuts can be positively secured against one another by a locking plate against unintentional loosening.
  • the trunnions can be provided at their ends adjacent to the bale with a driver pin, on which the bale is supported by feather keys.
  • the driver pins can be arranged eccentrically to the common axis of rotation and engage in corresponding eccentric recesses at the ends of the bale.
  • An eccentric can each be arranged on the trunnions, which engage in a form-fitting manner in corresponding lateral recesses in the ends of the bale.
  • the driving pins can be kept smaller in diameter than the trunnions. Their length is dimensioned such that they keep a certain distance from each other when installed. It is also possible for one drive pin to be extended beyond the center of the roller, so that the other drive pin can be kept correspondingly shorter or can even be omitted entirely.
  • the roller can be designed such that, for. B. a trunnion has a conical end on which the bale with a corresponding conical bore and e.g. is supported by keys, while the other end of the trunnion can be designed differently.
  • the roll barrel can be cylindrical or else calibrated. In particular, it is possible to calibrate the bale like a mit roller.
  • the drive pin and the trunnion are firmly but releasably connected to one another on the common axis of rotation by means of a threaded bolt with left and right-hand threads.
  • an axial threaded hole with a right-hand thread can be provided centrally in the trunnion, and an axial threaded hole with a left-hand thread or vice versa can also be provided centrally in the drive pin, into which the threaded bolt with its left-hand and right-hand thread is to be screwed.
  • the drive pins can have conical ends and the trunnions with corresponding conical bores can be mounted on the conical ends of the drive pins by means of feather keys.
  • the drive pins can have cylindrical ends and the trunnions are mounted with a corresponding cylindrical bore on the ends of the drive pins by means of feather keys.
  • the detachable connection of the drive pins to the trunnions by means of the threaded bolt offers the possibility of a roller in which e.g. a drive pin has been torn off to make it operational again without further ado. This can be particularly important if the roller cannot be repaired by welding or shrinking. This is also important if the drive pin runs in reversing mode and is therefore subject to increased wear in the coupling grooves.
  • the multi-part roller shown in FIG. 1 has a roller bale 10, here a caliber middle part 10 with a circumferential caliber groove 11.
  • the left-hand trunnion 12 in the illustration engages with an eccentric 13 in a correspondingly eccentrically designed recess 14 of the bale 10.
  • the right-hand trunnion 15 in the illustration has an eccentric flange 16 which engages in a form-fitting manner in a corresponding eccentric recess 17 of the bale 10.
  • An axis 18 of the trunnion 15 is guided coaxially to the two trunnions 12 and 15 and to the bale 10 and connected to the trunnion 12 via a threaded bolt 19 with right-hand thread 20 and left-hand thread 21.
  • the threaded bolt 19 is screwed in and out at the end using a square 22.
  • the roller shown in FIG. 2 is designed with its bale 10 as a mit roller with a corresponding groove 11.
  • the bale 10 has eccentric recesses 14 and 17 on both sides, in which corresponding eccentric flanges 13 and 16 engage in a form-fitting manner.
  • the axis 23 is eccentrically guided around the dimension 24 to the axis 25 of the trunnion 15. With 26 and 27, the two drive pins are designated.
  • the threaded bolt 19 is arranged concentrically to the trunnions 12 and 15 and eccentrically around the dimension 24 to the center line 28 of the axis 23.
  • the axis 23 is mounted eccentrically with respect to the common axis of rotation, it runs centrally through the caliber center. This means that the material of the bale 10 is distributed evenly around the axis 23 everywhere. As a result, the bale 10 and the axis 23 run coaxially with one another, which is of particular advantage for the special load cases in a pilgrim roller. On the other hand, this also means that the torque is no longer introduced into the bale 10 via the axis 23. The axis 23 therefore no longer needs to be designed for these loads, since the torque is introduced into the bale 10 exclusively via the flanges 13 and 16.
  • driver pins 29 and 30 are arranged concentrically with the trunnions 12 and 15, on which the bales are supported in a rotationally secure manner via keys 31 and 32.
  • the two driver pins 29 and 30 are connected to one another via the threaded bolt 19 with right-hand and left-hand threads and are kept smaller in diameter than the race pins 12 and 15.
  • the length of the driver pins 29 and 30 is dimensioned such that between the end faces of the two driver pins 29 and 30 a distance remains.
  • the driver pins 33 and 34 are arranged eccentrically to the trunnions 12 and 15 and positively engage in corresponding lateral recesses 35 and 36.
  • eccentrics 37 and 38 are also provided, which also engage in recesses associated with them on the two sides of the bale in a form-fitting manner.
  • the roller shown here is a pilgrim roller.
  • the bale 10 according to FIG. 5 has a conical bore 44, with which it is mounted on a conical end 47 of the trunnion 12 via keys 45 and 46.
  • the bale storage is cylindrical.
  • the two opposite trunnions 12 and 15 are also connected to one another via the threaded bolt 19. For the purpose of a secure connection of the two trunnions 12 and 15, they maintain a certain distance 48 in the assembled state.
  • FIG. 6 shows a roller, the bale 59 of which has four calibers 60, 61, 62 and 63.
  • the trunnions 64 and 65 are mounted with their eccentric flanges 66 and 67 in correspondingly formed recesses in the barrel 59 and engage in corresponding recesses 70 and 71 of the barrel 59 with threaded studs 68 and 69 which are kept smaller in diameter.
  • a threaded bolt 72 has ends 74 and 75 with threads on both sides of a central part.
  • the end 74 carries a right-hand external thread 76, which is screwed into the likewise right-hand internal thread 77 of the threaded pin 68.
  • the threaded bolt 72 is extended beyond the end 75 by a bolt part 80.
  • a right-hand and left-hand thread 81 is provided, which can be designed as a separate right-hand and left-hand thread or as a superimposed right-hand and left-hand thread.
  • Two nuts 82 and 83 are screwed onto the thread 81, the inner nut 82 having a right-hand thread and the outer nut 83 having a left-hand thread, or vice versa.
  • a locking plate 84 is provided between the two nuts 82 and 83 to prevent the nut 83 from loosening automatically.
  • the locking plate 84 carries at both ends a bend 85 and 86 to be produced by bending, the bend 85 engaging over the nut 82 and the bend 86 over the nut 83. This ensures that the nuts 82 and 83 cannot be displaced from the position once set on the threaded bolt 72. A strong tightening of both nuts 82 and 83 against each other by force locking is not necessary, so that the connection can always be easily and above all released without damage.
  • a square 87 is provided, by means of which the threaded bolt 72 can be rotated from the right and thus the roller parts can be clamped together or released from one another.
  • Fig. 7 shows the bolt part 80 of the threaded bolt 72 with the superimposed right and left-hand thread 81, the two nuts 82 and 83 and the locking plate 85 being omitted.
  • the right-hand thread is designated by 88 and the left-hand thread by 89.
  • FIG. 8 shows the bolt part 80 with nuts 82 and 83 screwed on and a locking plate 84 located between them with the bends 85 and 86.
  • a bale 90 is made in one piece with a trunnion 91.
  • a threaded bore 92 with a right-hand internal thread 93 is provided centrally in the trunnion 91.
  • the bore 92 merges into a conical bore 94, with which the trunnion 91 is mounted on the conical end 95 of a drive pin 96 by means of a key 97.
  • An axial threaded bore 98 with a left-hand internal thread 99 is likewise provided centrally in the drive pin 96.
  • the threaded bolt 100 is screwed into the two threaded bores 92 and 98.
  • This has a right-hand external thread at one end 101 and a left-hand external thread at its other end 102, so that by rotating the threaded bolt 100 by means of the square 103, the trunnion 91 and the drive pin 96 can be clamped together or released from one another.
  • the embodiment according to FIG. 10 differs from the embodiment shown in FIG. 9 essentially only in that the drive pin 96 has a cylindrical end 104. on which the trunnion 91 is mounted with a corresponding cylindrical bore 105 by means of a key 97.
  • FIGS. 9 and 10 offer the possibility of making a roller, the drive pin 96 of which has been torn off, functional again simply and with comparatively little effort by replacing the torn off drive pin 96 by a new one.
