Definitions

  • the invention relates to a cone sleeve for rolling mill rolls, in particular profiled rolling disks.
  • Cone sleeves of this type are used in rolling mills for rolling profiles, tubes and round material such as wires, in particular, because the two, often also three, elements used in these rolling mills are arranged at a mutual angle of 120 ° to one another and the profile is formed between their end faces by rolling disks subject to high loads, have a short service life and therefore have to be replaced frequently.
  • the worn rollers or roller disks for example shrunk onto the cone sleeve, can be removed from the drive shaft together with the sleeves and exchanged for new roller disks.
  • the invention is therefore based on the object of creating a conical sleeve which is simple in terms of production technology without the abovementioned disadvantages.
  • the sleeve consists of fiber-reinforced plastic, for example of multilayer wound, resin-impregnated fabric inserts.
  • Fabric inserts made of textile silk, glass, carbon or aramid fibers are preferred, which can advantageously be impregnated with polyester, epoxy or phenol in order to create a fiber-reinforced plastic sleeve, the surface of which is relatively rough in that the fibers of the Insert ends in the sleeve surface because the individual fibers of the insert are cut during surface processing to produce the taper. Due to the much better adhesion of the rough sleeve surface to the steel of the drive shaft, a pulling pressure of only approx.
  • the plastic sleeve is of the highest thermal and mechanical strength, cannot rust, is water-repellent and resistant to chemicals as well as greases, oils and emulsions. Should the plastic sleeve turn on the drive shaft during extreme operating loads, the material pairing of plastic and steel still excludes damage to the drive axle.
  • the fabric inserts should preferably consist of wound fibers.
  • the fibers can extend up to an angle of 90 ° to the longitudinal axis of the sleeve.
  • the sleeve can be given strength values specifically tailored to the respective application in any load direction.
  • a cone sleeve which preferably has an axially parallel slot with a rounded portion at the inner end, makes it easier to pull it onto the drive shaft because the slot acts as an expansion joint.
  • the conical sleeve 1 which receives a rolling disk (not shown) after mounting, has a bore 4 which widens from its rear end 2 in the drawing-up direction with an inner cone 3; it encloses the drive shaft, not shown, of a roll stand in the opened operating position.
  • a hub made of 42 Cr Mo 4 steel, for example, can also be located between the drive shaft and the conical sleeve.
  • the cone sleeve 1 consists of multilayer wound, resin-impregnated fabric inserts 5 made of textile silk, glass, carbon or aramid fibers.
  • the fibers 6 run at an angle 7 which promotes the strength of the sleeve 1 to the longitudinal axis 8 of the sleeve.
  • the hardener such as, in particular, unsaturated polyester, epoxy or phenol, gives the sleeve 1 high strength after curing.
  • the sleeve 1 is so tight on the drive shaft without the risk of spinning that a fastening wedge is not required.
  • the mounting of the conical sleeve 1 is facilitated by a slot 9 parallel to the longitudinal axis 8 of the sleeve with a fillet 10 at the inner slot end.
