Definitions

  • the invention relates to a rolling stand with a work roll floating in the rolling stand and rotatably mounted about an axially extending rotation axis with two axially opposite end faces.
  • rolling mills the shaping of a rolling stock, for example a steel, takes place on a roll stand. This shape is called rolling.
  • the rolling of the rolling stock is carried out between at least two work rolls (briefly below usually only rolls), which are in the roll stand - rotatable about their respective axially extending axis of rotation - are stored.
  • the structure of the roll stand depends on the number of rolls, the position of the rolls, the shape of the rolls, the forces acting during rolling and the accuracy requirements of the rolling stock. There are both rolling mills with only one as well as those with several nach- or side by side arranged roll stand (s).
  • a “floating” bearing (also often referred to as a “flying” bearing) is understood to mean a bearing of an element extending around an axially extending axis of rotation, such as the roller, which bearing (with respect to the axially extending rotational axis of the rotating element) in the axial direction has a game / allows, ie, the (Float to be stored) element is not clearly fixed in the axial direction.
  • the (Float to be stored) element is not clearly fixed in the axial direction.
  • rollers Since, in such small diameter rollers, the (drive) torque - due to mechanical reasons - can no longer be directly transmitted via a drive pin arranged on the (end face) of the roller, such rollers are exclusively supported by - parallel (with respect to their respective axes of rotation) Rolls arranged and about their respective lateral surfaces / surfaces in frictional or frictional contact with the (driven) rollers standing - (rotatably mounted about their own respective rotation axes) intermediate rollers driven.
  • these rollers are also - based on the strip running direction - laterally, d. H. at its (two) axial end faces of other (also rotatably mounted about their own rotation axes) support rollers or support rollers - by adhesion or friction (roller and backup roller / - roll or the outer surfaces / surfaces roll off) - supported.
  • Such - the roller axially supporting - sees support - (also) in (with respect to its axis of rotation) axial direction - curved tread / lateral surface / surface ("Barrel shape"), whose diameter-largest circumferential circle (circumferential circles or peripheral circular surfaces are obtained by cuts through the support roller normal to the axis of rotation) with respect to the axis of rotation of the roller is radially offset.
  • the roller has a mechanical play in the axial direction, so that not always both sides of both support rollers are touched simultaneously, but the roller between them "floats free”.
  • An object of the invention is to provide a roll stand with at least one work roll mounted therein, which avoids the disadvantages of the prior art, in particular in which such friction and wear behavior is avoided or improved.
  • the mill stand which has a work roll (in the following only roll) rotatably mounted in the mill stand and rotatable about an axially extending axis of rotation, has at least one bearing assembly which is arranged on one of the two end faces of the work roll and which has a housing in which the work roll is mounted using a fixed bearing.
  • the roller is then floatingly supported in the rolling stand.
  • D. h. Simplified and in short, the bearing assembly, which supports the roller by means of solid storage, is "floating" added to the rolling mill.
  • such a bearing assembly in whose housing the roller is accommodated by means of the fixed bearing, can also be arranged on each of the two end faces of the roller.
  • a bearing arrangement can be understood as a bearing concept or a bearing / bearing arrangement (for mounting a component rotating around an axially rotating axis such as the roller), which or which the component to be supported or the roller in the axial direction (with respect the axis of rotation) clearly positioned.
  • Such a fixed bearing will thus absorb both radial forces and axial forces (axial forces in both axial directions) and guide them into a component to be supported or the roller "surrounding" construction, such as a housing or the housing of the bearing assembly.
  • This fixed bearing can in principle be taken up by a single bearing, for example a roller bearing (or possibly also a slide bearing), (here a bearing receives both the axial forces and the radial forces, such as a deep groove ball bearing or a four point bearing with non-displaceably arranged outer bearings. or inner rings) are met.
  • a roller bearing or possibly also a slide bearing
  • a bearing receives both the axial forces and the radial forces, such as a deep groove ball bearing or a four point bearing with non-displaceably arranged outer bearings. or inner rings
  • two bearings for example two roller bearings (or optionally also two plain bearings), are often used to fulfill the fixed bearing function, for example an employed (roller) bearing (Here are two fixed bearing braced against each other, for example, two mirror-image angular contact ball bearings or tapered roller bearings) or a fixed-lot storage (here the axial and radial forces are divided separately into two bearings, ie exclusively axial forces receiving thrust bearing and exclusively the radial forces receiving Radial bearings, such as a cylindrical roller bearing (for the radial forces) with a thrust roller bearing (for the axial forces)).
  • the fixed bearing by means of rolling bearings, they may, in order to reduce friction and wear, grease lubricated or oil lubricated, in particular grease lubricated be.
  • “Floating supported” means in particular that the supported component, here the roller (in the roll stand), in its position not fixed or fixed (in the rolling stand) is fixed (ie “floating” (or translationally displaceable) and via the bearing assembly “only” is supported, whereby so then the roller or assembly of roller and bearing assembly is included in the rolling mill), but (translational) degrees of freedom (for the roller) are possible, which is a (translational) position change of the roller allow in the mill, for example, an axial and / or horizontal displaceability of the roller.
  • the invention is based on the consideration and knowledge that in the storage of the roller with the previous rolling on the rotating roller roller - due to rolling on the rotating roller roller - in a component, d. h./namely the support roller, both a "(static) support function” (here the roller is axially supported) and at the same time a “freedom of movement function” (here the rotational movement or the rotational degree of freedom of the roller by a dynamic rolling movement between the roller and the support roller allows) is combined.
  • a "(static) support function” here the roller is axially supported
  • a freedom of movement function here the rotational movement or the rotational degree of freedom of the roller by a dynamic rolling movement between the roller and the support roller allows
  • the invention provides a "structural and functional" separation or separation of these two functions, ie. H. the "static support function” and “freedom of movement function", before.
  • the realization of the "freedom of movement function” is characterized in that the work roll - by means of one or the - "classic” - fixed storage - stored / recorded in the bearing assembly or its housing.
  • the rotatory Degree of freedom is - exclusively - made possible by the fixed bearing, - whereby - in "fixed” (ie non-rotating) housing or the bearing assembly - the roller rotates relative to the "stationary" housing or bearing assembly.
  • the "static support function" for the roller
  • the housing or the bearing assembly in the rolling stand for example in a local rolling stand, "supported or taken up”.
  • the fixed bearing is realized by using a roller bearing arrangement, in particular an employed rolling bearing arrangement.
  • the rolling bearing arrangement forming the fixed bearing can be realized by means of a single (roller) bearing, but in particular - just necessarily in the case of an employed (roller) bearing - by means of two (or possibly even more) (roller) bearings.
  • the employment of the rolling bearing arrangement can be realized in the form of an X arrangement or an O arrangement.
  • the employment may be an O-arrangement.
  • the rolling bearing arrangement in particular the employed rolling bearing arrangement, is realized by using at least one first and at least one second set of tapered roller bearings or spherical roller bearings or angular contact ball bearings.
