  • the present invention relates to roller bearing means for journaling roller cylinders in a universal mill roll support.
  • Mill roll supports comprise an open sided box-like structure in which a supporting axle, passing through the center bore of the mill roll, is mounted.
  • a multi row roller bearing is interposed between the axle and the roll and is provided at both ends with an annular disc shaped cover member which seals the bearing.
  • a roll supporting frame in which means are provided so that the roll may be removed in a vertically upward direction.
  • This means comprises a structure which is slidably movable during assembly or disassembly along guide rails and in which the driver of the mill roll is seated in an intermediate piece journaled in the frame.
  • the intermediate piece removably carries the drum spindles.
  • -It is an object of the present invention to provide a journal by which the mill roll may be horizontally or vertically installed or disassembled.
  • a roller bearing having a box-like supporting structure open on one side, in which the mill roll can be inserted.
  • an axle In the axial bore of the mill roll there is located an axle about which an annular plural rowed roller bearing is arranged.
  • the axle is provided with a pair of annular ring shaped side covering members which enclose the bearing.
  • Each of the ring shaped covering members is formed as a part of a unitary integral slide which in plan view is rectanand which may be removably fastened to the box support structure.
  • the mill roll forms with the roller bearing and the side bearing cover pieces form with the slide member a completely enclosed unitary assembly which can be easily removed from the box supporting structure by lifting the entire assembly in a direction counter to the direction of its load. Furthermore, when it is necessary to remill the external surfaces of the mill roll, the entire unitary assembly can be turned while still maintained directly in the roller frame. By this construction an excessive number of box supporting frames is not necessary. Furthermore, the present construction has the advantage in that'only a very little amount of space is necessary in order to install or disassemble the arrangement and hoists or lifting tools may be used to lift the entire assembly. Still a further advantage arises from the fact that both axial and radial forces are more assuredly absorbed by the box-like structure when the bearing of the present invention is employed.
  • At least one step like guide rail is arranged between the annular disc like cover and the slide.
  • the arms of the slide are provided with seats which cooperate with the edge of the box supporting structure to provide an interlocking engagement between the two.
  • both ends of the axle be provided with covers having slides which are similarly formed so that the members at each end of the assembly are the same. This reduces the number of parts necessary and makes the task of assembly much easier.
  • FIG. 1 is a sectional view through a vertical mill roll I and bearing having mill roll, which is removable in the DESCRIPTION OF INVENTION
  • a box-like supporting structure 1 is shown having one of its sides open.
  • a vertical mill roll 2 is lo-. cated within the box supporting structure and is journaled by means of a multi row roller bearing 3 about an axle 4 which is fixedly mounted in a manner to be seen.
  • the roller bearing 3 comprises four rows of tapered or conical roller elements set between an outer ring 5 and an inner ring 6.
  • the inner ring 6 is provided with guide rims 7 and a retaining rim 8.
  • the tapered roller elements generally bearing the reference numeral 9 are held within a cage 10 in conventional manner.
  • Compensating discs or shims 11 are arranged at each of the axial sides of the multi rowed roller bearing.
  • the ring-like or annular disc shaped cover 12 is pressed against each of the shims 1 1.
  • the ring shaped cover is one piece with a slide 13 which in plan view is rectangularly shaped.
  • the cover and slide unit is formed from a single casting or single piece of machine worked metal.
  • the rectangular slide is slidable in a similarly shaped rectangular opening 14 formed in the side of the box supporting structure 1 opening from its upper edge.
  • arms 15 Extending in opposite directions from the upper edge of the slide 13 are arms 15 which are adapted to rest on the upper edge of the box-like supporting structure and which are by means of bolts 16 removably fastened to the box 1.
  • the slide 13 is also secured to the axle 4 by means of bolts 7 as seen more clearly in FIG. 3.
  • the opposite end pieces 18 of the axle 14, which are reduced in diameter are located in a circular opening 19 formed in the slide 13.
  • a sealing ring 20 which serves to seal the multi rowed taper roller bearing 3.
  • An annular cover ring 21 is fastened to the mill roll 2 by means of bolts 22.
  • the lateral edge 23 of the annular ring 21 bears against the outer ring of the bearing 3.
  • That portion of the. annular disc bearing 12 facing the annular covering ring 21 is formed with a groove24 in which a rectangular sealing member 25 is located.
  • the sealing member 25 is similar to a piston seal ring and acts to seal the roller bearing 3 from the radially external side while permitting the mill roll 2 to rotate about the bearing.
  • An inlet bore 26 extends from the exterior of the device into the chamber formed by the inner and outer rings of the bearing 3. Through this inlet bore 26 conventional and suitable lubricant can be fed to the bearing.
  • bearing 3 is symmetrically formed and that the both sides are the same. Further, the construction of the slide members and its integral covering ring 13 and 12, respectively, are also the same at both of the lateral sides of the device.
  • FIG. 4 shows clearly the guide rails 29 which are shown in cross section in FIG. 3 and in the dot-dash in FIG. 2. These guide rails are set at the junction of the annular cover 12 and the slide 13 and fit within a correspondingly formed slot in the edges of the rectangular opening in the sides of the box supporting structure. These guide rails transmit the axial forces to the box support structure 1.
  • the slide 13 is formed with a flat edge 30 which when it is placed in position rests contiguously on the bottom edge 14a of the rectangular open ing- 14 in the box-like support. This edge 30 transmits the radial forces to the box-like structure.
  • the arms extending laterally from the slide 13 are formed with extending seats 31 which are adapted to seat within a correspondingly formed receiving seat on the upper edge of the box supporting structure 1 to form with it an interlocking engagement.
  • the bolts 16 are removed and the cover 12 with its integral slide 13, the bearing 3 and the mill roll itself are removed in the horizontal direction shown by the enlarged arrow.
  • the entire bearing assembly axle and mill roll can be removed bodily from the supporting structure.
  • the entire assembly can then be placed on a work structure having similar supporting elements which supporting structure allows sufficient room for the operator to work and which will allow the mill roll to be turned and milled.
  • a supporting structure away from the mill roll apparatus has a further advantage in that in such a supporting structure suitable measuring and testing apparatus may be freely employed to test the proper functioning of the mill roll. For example, an impact impulse testing apparatus may be used. Further, correction or repair can be more easily made at this remote position.
  • FIGS. 1 through 4 show the adaption of the present invention for handling vertical mill rolls, it will be obvious to those skilled in this art that the same apparatus and the same principles can be employed for journalling horizontal mill rolls.
  • FIG. 1 By turning the apparatus shown in FIG. 1 clockwise about a angle and the apparatus as shown in FIG. 4 counterclockwise in a 90 angle, such a horizontal mill roll bearing will be apparent.
  • FIG. 2 will then become a side elevation view while FIG. 3 becomes a horizontal cross section through the bearing shown in FIG. 1. Because of the symmetry of the apparatus and because the axial and radial forces are absorbed completely in either direction this disposition from vertical to horizontal can be made without any modification or changes required.
  • the mill roll, its axle and multi rowed bearing assembly constitute a single unit which can be fastened to the box-like supporting structure in both vertical and horizontal positions.
  • the covers 12 bear axially against each edge of the bearings 3 and thus by use of annular shims ll of uniform thickness the central location of the bearing 3 and mill roll 2 can be insured with respect to the hollowed out opening of the boxlike supporting structure.
  • this construction insures that the bearing 3 itself is centered within the bore of the mill roll 2 and lies symmetrically with respect to the central plane of the mill roll.
  • a journal for universal mill rolls and the like comprising a mill roll located in a supporting structure having opposed side walls, said mill roll being provided with a roller bearing and axle located within its bore and supported on the side walls, ring shaped cover members sealing each of the axial ends of said roller bearing, said ring shaped covers being formed integrally with a slide member having a rectangular shape when viewed in plan, said slide member being insertable within a rectangular opening in the side wall of said supporting structure and having a pair of extending arms engaging the edge of said side wall and means for removably connecting said arms to said side wall.
  • roller bearing comprises a plurality of annular rows of tapered roller bearing elements.
  • the journal of claim 1 including at least one step shaped guide rail arranged between the juncture of the slide and the ring cover seal.
  • each of the arms of the slide member are provided with seats to center said roller bearing within the mill roll.
