Definitions

  • the invention relates to a roller, the bale of which is provided at both ends with a trunnion.
  • 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.
  • the known rollers are in one piece. Since in general the bale or the calibration medium part wear out faster than the other roller parts, that is to say the trunnions and the drive journal, it is necessary to replace the entire roller with a new one as soon as the caliber central part or the bale is worn out; this means that the trunnion and the drive pin must also 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 there is a shrink fit with an exact fit 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 to a limited extent; in addition, 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.
  • the invention has for its object to provide a roller of the type mentioned so that after wear of the most stressed part of the roller only this part needs to be replaced with a new one, while the remaining parts of the roller can continue to be used.
  • the center section of the caliber, or the bale and the trunnion can be designed specifically and differently depending on the operational conditions, for example taking into account wear, thermal shock, hot or cold welding, strength, toughness, surface refinement, saturation technology during casting, and roll calibration , the roller geometry etc.
  • the trunnions each have a flange with which they engage in a form-fitting manner in recesses provided at both ends of the bale.
  • 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. This offers the possibility that the roller is driven via the eccentric flange from the drive side and also drives the other trunnion via the eccentric flange with the bale at the same speed.
  • An axis projecting through the bale is expediently provided on one of the trunnions and is connected to the other trunnion.
  • the axis is integrally connected to the trunnion and pulled through the bale.
  • the connection point between the two trunnions is det 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 mit roller.
  • the axis can be mounted coaxially with the common axis of rotation.
  • the torque is introduced into the bale exclusively via the eccentric flanges.
  • This arrangement is advantageous in the case of a bale which is designed symmetrically to its axis of rotation.
  • 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 two trunnions are advantageously over the Axle is firmly but releasably connected by means of a threaded bolt with right and left hand threads.
  • a threaded bolt with right and left hand threads.
  • Such a threaded bolt is provided with a right-hand thread on one half and a left-hand thread on its other half, so that by rotating the threaded bolt in only one direction, for example to the right, the components to be connected are pulled towards one another.
  • 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 so that it carries a continuous superimposed right and left-hand thread, in such a way that a continuous right-hand thread is also superimposed on a continuous left-hand thread or vice versa.
  • the right-hand thread and the left-hand thread have the same pitch.
  • a further right-hand and left-hand thread can be provided for bracing 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-hand and left-hand versions. Furthermore, the two nuts can be positively secured against each other 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 mounted by means of feather keys.
  • the driver pins can be eccentric to the common axis of rotation be ordered 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 such that they maintain 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 e.g. a trunnion has a conical end on which the bale has a corresponding conical bore and e.g. is supported by keys, while the other end of the trunnion can be designed differently.
  • both trunnions have conical ends and the bale is fitted with a corresponding double-conical bore on the two conical ends of the trunnions by means of feather keys.
  • the two opposite pins are held together by means of a threaded bolt with right and left hand threads.
  • 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 bore with a right-hand thread can be provided centrally in the trunnion, and an axial threaded bore with a left-hand thread or vice versa can also be provided centrally in the drive journal, 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 can be mounted on the conical ends of the drive pins by means of feather keys with corresponding conical bores.
  • the drive pins 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 center 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 in 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 on the end face via a square 22.
  • the roller shown in FIG. 2 is designed with its bale 10 as a pilgrim 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 guided eccentrically to the axis 25 of the trunnion 15 by the dimension 24.
  • the two drive pins are designated.
  • the threaded bolt 19 is arranged concentrically to the trunnions 12 and 15 and eccentrically by 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 ver evenly around the axis 23 everywhere shares. 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 feather keys 31 and 32.
  • the two driver pins 29 and 30 are connected via the threaded bolt 19 with right and left hand threads and are kept smaller in diameter than the trunnions 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, the recesses also assigned in them Intervene positively on both sides of the bale.
  • the roller shown here is a pilgrim roller.
  • pins 39 and 40 with a somewhat smaller diameter are arranged on the trunnions 12 and 15.
  • the bale 10 is rotatably supported on the left-hand side by means of the clamping sleeve consisting of the two rings 41 and 42, while the conical pin 40 is mounted on the conical sleeve 58.
  • the two trunnions 12 and 15 are connected to one another by a screw 43.
  • the bale 10 according to FIG. 6 has a conical bore 44, with which it is supported on parallel keys 45 and 46 on a conical end 47 of the trunnion 12.
  • 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.
  • the bale 10 according to FIG. 7 is provided with a double-conical bore 49, 50, with which it is mounted on the two conical ends 55 and 56 of the trunnions 12 and 15 via a plurality of parallel keys 51, 52, 53 and 54.
  • the two trunnions 12 and 15 are connected via the threaded bolt 19 with right and left-hand threads so that a distance 57 remains between the two end faces of the conical ends 55 and 56 of the trunnions 12 and 15.
  • FIG. 8 shows a roller whose bale 59 has four calibers 60, 61, 62 and 63.
  • the trunnions 64 and 65 are mounted with their eccentric flanges 66 and 67 in correspondingly shaped 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 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 frictional connection is not required, so that the connection can always be solved easily and above all 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. 9 shows the bolt part 80 of the threaded bolt 72 with the superimposed right-hand 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. 10 shows the bolt part 80 with nuts 82 and 83 screwed on and a locking plate 84 located therebetween 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 feather 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.
  • FIGS. 11 and 12 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.
