Definitions

  • the present invention relates to a roll bearing device, preferably for rolling mills, and has for its object to improve the usual roll bearing or, more strictly speaking to replace them by a construction, which is less bulky, provides better possibilities of mounting of the rolls and enables a more rapid exchange of rolls; the new construction having the important advantage that the rolling pressure is unloaded from the frame and is instead transferred from one bearing box directly to the other via so-called stay-screws.
  • the construction is also intended to utilize as much as possible the advantages which may be obtained by use of roller bearings and other exactly made bearing constructions.
  • Essentially characteristic for the construction is i. a. that posts have been substituted for the roll casings, which posts support and guide the bearing boxes.
  • the construction as a whole and its different features may be said to be based on this constructional detail, as will be seen from the following.
  • Figs. 1-7 relate to two high mills and Figs. 8, 9 and 10 to three high mills.
  • Fig. 1 shows a section II of the pair of rolls of Fig. 2, while Fig. 2 shows a front view of the pair of rolls.
  • Fig. 3 shows a section along the broken line III-III of Fig. 1 with some parts added.
  • Fig. 4 shows an end View of a pair of rolls carried by its posts and Fig. 5 a front view of two pairs of rolls of the reciprocating two high mill, which are mounted in a similar manner.
  • Fig. 6 shows a pair Of rolls in a radial section and Fig. 7 a detail section along the line VIIVII of Fig. 6.
  • Fig. 8 shows a front view of the three high mill rolls and Fig. 9 in the left half a radial section and in the right half an end view of the three high mill rolls.
  • Fig. 10 shows a plan view of three high mill roll pairs without adjusting device for the rolls.
  • top, intermediate and bottom rolls are designated by i, la and 2 respectively and their bearing boxes with 3, 3b and respectively.
  • the mounting of the rolls is seen in Fig. 3, the upper section of which shows the known SKF-construction with spherical roller bearings 55 for the roll journals 3a, two for each journal.
  • the journal situated to the left has a shoulder and the narrower outer part of it is resting in a roller bearing provided with a divided outer ring 5a guiding the rolls in the axial direction.
  • the bearing boxes are supported and guided by posts 6 (Figs. 3, 4 and 5) each resting on a separate base plate 1.
  • Each post with its base plate is used instead of a bearing casing and is according to the invention provided with a guide, in the first place for the two bearing boxes, which are situated at the same side of the pair of rolls and of the post.
  • the post can at the same time form a guide at its other side for the bearing boxes of another pair of rolls, for instance in two high mills according to Fig. 3, in which the post has a T-profile, the flanges 8 constituting the guides themselves.
  • Posts intended to guide only at one side may for instance have L-profile.
  • In the bearing boxes there are recesses 9 corresponding to the flanges.
  • the bearing boxes 3, 4 respectively at each side are connected to each other by means of two stay-screws I2 (Fig. 1.).
  • a head l3 on the screw and a bushing I4 fixed in the lower bearing box 4 each stay-screw is fastened in this bearing box, and by means of a nut l0, fixed in the upper bearing box 3 and provided with screw threads for the stay-screw, a screw connection is obtained which enables the desired change of the distance between the rolls.
  • the reference numeral l5 designates distance bars and I6 and I! an elastic suspension of the top roll, which eliminates the play in the threads and at the head I 3 of the stay-screws.
  • the stay-screws are synchronised by, for instance, a worm gear [8, [9 which isadapted to be turned by means of a handwheel 20, Figs. 4. and 5, or by an electric motor.
  • Fig. 5 the bottom roll of the pair of rolls to the right is stationary, that is to say that its bearing boxes rest in the post for instance on adjusting screws 22, and may be immobilized by means of screw bolts 23.
  • the top roll I consequently can be raised and lowered.
  • the top roll i is stationary and the bottom roll 2 is adjustable as to the height, that is to say it hangs in the stay-screws i2.
  • the conducting devices consist of' separate lower scrapers and separate upper scrapers, it'is; notnecessary to adjust the conducting devices when the position of the rolls-is. changed. This is especially important in fore-pairs with adjust.-
  • the bearing boxes. will nottbc so broad. as a roll 7 housing whereby'the conducting devices become more easily accessible. and it will be. easier to control that the conducting devices are. correctly po sitioned.
  • the cooling water. supply tubes. may be mounted in the posts and the coolingwater tubes in Figs; 6 and. 7 may be provided with: fixed splash plates 3'8. Thus. loose protection plates, wood blocks, waste and other provisional splash plates may be obviated. For the sake.
  • the posts have been fGl-med wtih:guiding surfaces, so that the: pairs 1 of rolls. may be completely mounted. and, provided 7 with conducting devices and cooling water supply tubes outsiderthe train.
  • Thefexchange-foi rolls 4 therefore will become very easy and quick and is done as follows:
  • the middle roll la is supposed to be fixed, while the top roll and the bottom r011 are adjusted by their individual stay-screws 12.
  • the bearing box may be carried and guided by posts in fundamentally the same manner as has been described above.
  • the post has, however, a somewhat different profile from that described above.
  • the top roll as well as the bottom roll hasa spring device l6, l1.
  • A- rolling mill comprising a pair or axially V aligned bearing blocks, a roll having 'e-Iid' journals journailed insaid bearing blocks, a secondpair of axially aligned bearingblocks. in. superposed relationto said first. pair, a second roll having endjournals journalled the second pairpf 7 'bearingjblocks', vertically extending spaced parallel stay screws'm'oun't'ed' in and restrained from axial movement with respect to each of' the bearingblocks of the 'firstpa'in said second pair of bearing blocks each having spaced parallel vertical bores" therein through which said stay screws extend to mount the upper bearing blocks on the respective stay screws.
  • each of the upright supporting standards having a vertical guide flange thereon with the guide flange on one in opposed relation to and disposed in the same vertical plane as the guide flange on the other and said bearing blocks each having a vertical channel in the outer end faces thereof adapted for vertical sliding engagement with the respective opposed guide flanges on said upright standards to removably support the bearing block and roll assembly on said standards, the vertical channels in the end faces of the bearing blocks being ofiset to one side of the axis of the journals therein.
