Definitions

  • the invention relates to a roller bearing with chocks, in which a roll extending along the Waize ⁇ achse is mounted for rolling a metal strip with the roll neck, wherein each chock is connected to the roll pin via a retaining ring and adjusting rings.
  • the existing part rings are normally loosened, split retaining rings are dismantled and only then can the chocks be axially removed from the rollers.
  • the retaining rings and setting rings are set aside so that it cannot be ruled out that parts can also get lost or be misplaced in the usually rough metallurgical operation.
  • these are of course required if - in reverse order - the assembly takes place again.
  • the object of the invention is therefore to provide a roller bearing that allows a significantly simplified assembly and disassembly of the rollers.
  • the retaining ring consists of a bayonet ring which is supported on the roll neck in the state in which the roller locks against the chock and which is rotatably mounted relative to the latter in order to move from the locked state to a disassembly state in which the chock is axially removable from the roll neck.
  • the bayonet ring is supported on the roll pin, on cams provided on it.
  • the adjusting rings consist in the usual way of two rings arranged axially one behind the other, which are connected to one another via an internal or external thread in such a way that the axial distance from one another can be changed, so that the axial play of the bearings can be adjusted in this way.
  • a feather key is inserted into a groove provided on the setting rings.
  • the bayonet ring can be connected non-rotatably to the one setting ring via screws arranged coaxially to the roller axis, elongated holes being provided in the bayonet ring, in which screws provided on the setting ring are guided, so that the bayonet ring can be rotated relative to the corresponding setting ring by the angle predetermined by the elongated holes.
  • a circlip extending over half the circumference is provided on the chock to hold both the bayonet ring and the parting rings when the chock is removed from the roll neck.
  • FIG. 1 shows a partial longitudinal section through the chock with roll neck and roll
  • Figure 2 is a front view of the chock
  • Figure 3 is a front view and a section through the bayonet ring.
  • a chock 2 is pushed onto the roller 1, only one side of the roller bearing being shown in the drawing, i.e. the opposite side of the roller is supported accordingly.
  • cams or, if necessary, incisions 3 are provided which cooperate with the bayonet ring 4. Depending on Rotation of the bayonet ring, relative to these cams 3, the cams 3 come with. Cams on the bayonet ring are in engagement with one another or enable the bayonet ring to be axially displaced in the direction of the roll pin end or roll center.
  • oblong holes 5 are provided on the end face, which receive screws 8, by means of which the bayonet ring can be rotated on the one hand relative to the setting ring 6, which receives the screws, and on the other hand is held by the latter.
  • a locking ring 7 is now provided, which surrounds the lower region of the adjusting ring in a semicircular shape and is firmly connected to the chock.
  • This circlip is now designed so that when the chock is removed, both the setting rings and the bayonet ring on the chock are retained.
  • the construction of the roller bearing according to the invention has the advantage that adjustment work can only be carried out once or only after the bearing has been changed.

Abstract

L'invention concerne un palier de laminoir comportant des inserts dans lesquels un cylindre (1), destiné au laminage d'une bande métallique, s'étendant le long de l'axe de cylindre, est logé au moyen du tourillon de cylindre (9), chaque insert (2) étant relié au tourillon de cylindre (9) par l'intermédiaire d'un anneau de maintien (4) et d'anneaux de réglage (6). L'anneau de maintien (4) est composé d'un anneau à baïonnette s'appuyant sur le tourillon de cylindre (9) dans l'état de blocage du cylindre par rapport à l'insert. Par ailleurs, ledit anneau à baïonnette est logé de façon rotative par rapport audit tourillon de cylindre afin de passer d'un état de blocage vers un état de démontage dans lequel l'insert (2) peut être retiré axialement du tourillon de cylindre (9).
