Definitions

  • This invention relates generally to rolling mill roller guides, and is concerned in particular with an improved means for pre-spinning the guide rollers in advance of the arrival of a mill product therebetween.
  • FIG. 1 is a plan view of a roller entry guide in accordance with the present invention
  • FIG. 2 is a horizontal sectional view on an enlarged scale taken through one of the guide rollers
  • FIG. 3 is a sectional view taken along line 3 - 3 of FIG. 2 ;
  • FIG. 4 is a view similar to FIG. 2 showing an alternative embodiment of the invention.
  • FIG. 5 is a sectional view taken along line 5 - 5 of FIG. 4 .
  • the objective of the present invention is to provide an improved means for driving the guide rollers that avoids the aforementioned drawbacks of the prior art.
  • a roller entry guide has mutually spaced annular rollers arranged to contact opposite sides of a product, e.g., hot rolled steel rod, moving at high speed along a path.
  • the rollers are supported on respective shafts by bearings defining axial gaps therebetween.
  • the gaps are surrounded by vanes carried by the rollers.
  • a pressurized fluid typically an oil mist, is delivered to the axial gaps via passageways in the shafts.
  • the oil mist impinges on the vanes to rotatably drive the rollers, and also serves as a lubricant for the roller bearings.
  • a roller entry guide in accordance with the present invention is generally indicated at 10 .
  • the guide includes a housing 12 supporting a pair of arms 14 pivotally adjustable about axes 16 .
  • the projecting distal ends of the arms carry annular guide rollers 18 rotatably mounted on respective shafts 20 .
  • the guide rollers are arranged to contact opposite sides of a product, typically hot rolled steel rod 22 , moving at high speed along a path “P” into a roll stand (not shown).
  • each guide roller 18 is rotatably supported on its respective shaft 20 by bearings 24 defining an axial gap 26 there between.
  • the bearings preferably comprise roller bearings having inner races 24 a fixed with respect to the shaft 20 , and outer races 24 b fixed with respect to the interior of the roller 18 .
  • a spacer 28 is interposed between the inner bearings races 24 a .
  • the spacer is surrounded by a series of vanes indicated typically at 30 and formed on an interior surface of the guide roller 18 .
  • An axially extending passageway 32 in shaft 20 is arranged to direct a flow of pressurized fluid to radial passageways 34 communicating with a circular passageway 36 formed by confronting grooves in the shaft 32 and spacer 28 .
  • Nozzles 38 in the spacer lead from the passageway 36 and are arranged to direct the pressurized fluid against the vanes 30 to thereby rotatably drive and pre-spin the rollers 18 .
  • the pressurized fluid is advantageously an oil mist which serves the added purpose of lubricating the bearings 24 .
  • FIGS. 4 and 5 The embodiment shown in FIGS. 4 and 5 is largely identical to that shown in FIGS. 2 and 3 , except that the vanes 30 ′ are formed on the interior of a bushing 40 pressed into the interior of the guide roller 18 .
  • each roller need only be provided with one array of internal vanes.
  • the rollers are rotatably driven by the same pressurized fluid that also serves as the lubricant for the roller bearings. No potentially troublesome external application of cooling water is required, and the internal vanes can serve to rotate the rollers in either direction, thus enabling the rollers to be reversed.
  • roller entry guides While the internal pre-spinning and lubrication system of the present invention has been described with reference to roller entry guides, it should be understood that the same concept can be utilized to pre-spin and lubricate rollers in other rolling mill applications where rollers are used to guide the hot rolled product along curved paths.
  • One non-limiting example of such an application would be to pre-spin and lubricate the rollers of a rollerized guide directing the hot rolled product into an inclined laying head.
