Definitions

  • ABSTRACT A textile beam construction consisting of a barrel and a cast aluminum head secured to each end thereof. Each head has a hub portion with a cylindrical surface extending axially of the beam and has a retaining surface extending outwardly in radial relation to the cylindrical surface. An annular concave surface or fillet is formed on each head at the junction between the cylindrical and retaining surfaces, and the ultimate strength of each head is materially increased by providing residual compressive stress in the material forming the annular fillet.
  • This fillet is initially formed on a radius greater than the desired finished radius, and a rolling operation is carried out on the fillet surface to apply a compressive force which reduces the radius to finished dimension and creates the residual compressive stress in the cast material of the head forming the fillet surface.
  • This invention relates to an improved construction for a textile beam or spool having a cast aluminum head secured to each end of a central portion or barrel, and to an improved method for manufacturing such a head of cast aluminum to provide the desired amount of ultimate strength.
  • a textile beam or relatively large spool consists of a cylindrical barrel to which a pair of heads are secured, each head having a hub with a cylindrical surface portion at one end of the barrel and extending axially thereof, and having a retaining surface portion extending radially outward of the hub.
  • the heads of the beam have been made as aluminum forgings, and while this adds considerable expense to the article, no other type of construction has been known which satisfies the requirements for minimum weight and for sufficient strength to withstand the high loads imposed when the beam is wound with yarn.
  • Beams or spools have been manufactured with heads made of cast aluminum, but only in smaller sizes and for light duty service because of the relatively low ultimate strength of this type of construction.
  • the present invention provides a beam construction in which the forged aluminum heads can be replaced at an appreciable saving in cost with heads made of aluminum castings and having an ultimate breaking strength suitable for tricot and other relatively high loading applications.
  • the invention also provides a method for commercially manufacturing a cast aluminum head for a beam or spool having a marked increase in ultimate breaking strength in comparison with such a cast aluminum head produced without the use of this method.
  • each head has a hub with a cylindrical surface forming a continuation of the barrel and has a retaining surface extending radially outward from the cylindrical surface.
  • Each head consists of an aluminum casting provided with an annular concave surface forming a fillet at the junction between the cylindrical and retaining surfaces thereof, and the cast aluminum material forming the annular fillet has a residual compressive stress provided therein when the beam is in an unloaded condition.
  • this residual compressive stress is on the order of 25,000 lbs. per square inch.
  • the invention provides a method for making a cast aluminum head for a textile beam or spool in which the concave fillet formed at the junction between the cylindrical and retaining surfaces of the head is initially formed with a radius having a dimension in excess of that desired for the finished dimension of the radius of this fillet, and a compressive force is applied to the annular fillet surface to reduce the dimension of the radius thereof to the desired finished dimension and to thereby create the residual compressive stress in the material of the head forming the annular fillet surface.
  • the method is carried out by employing a roller provided with a convex peripheral profile formed on a radius having the dimension of the finished radius of the fillet; and, this roller is additionally provided with marginal portions bordering the convex peripheral profile, which marginal portions are at right angles to each other and engage the cylindrical and retaining surfaces of the head during the rolling operation to limit the action of the compressive force applied to the fillet surface.
  • FIG. 1 is an elevation showing the principal components of a textile beam or spool and illustrating the forces to which these components are subjected when a material is wound thereon;
  • FIG. 2 is an enlarged sectional detail taken through a head of a beam constructed in accordance with the invention and showing the junction between the hub and yarn retaining surface portions thereof;
  • FIG. 3 is a sectional detail similar to FIG. 2 illustrating a method for the manufacture of a cast aluminum beam head according to the invention.
  • a conventional textile beam 10 schematically illustrated in FIG. 1, consists of a cylindrical barrel 12 whose axis defines the axis of the beam, and a head 14 suitably connected to the barrel at each end 15 thereof.
  • Each head 14 has a hub 16 with a cylindrical surface 17 extending axially of the beam to form a continuation of the cylindrical barrel 12, and has a retaining surface 18 extending radially outward of the cylindrical surface 17.
  • FIG. 2 gives an enlarged sectional view of the junction between the cylindrical surface 17 and retaining surface 18 of the head of a beam constructed in accor dance with the invention.
  • a portion of the barrel 12 is indicated in broken line together with a connection between the hub 16 and the barrel 12 such as disclosed in U.S. Pat. No. 3,317,160.
  • the head 14 shown in FIG. 2 comprises an aluminum casting provided with the annular concave surface or fillet 24 at the junction between the cylindrical surface 17 and the yarn returning surface 18 of the head.
  • the cast aluminum material which forms the annular fillet 24 has a residual compressive stress provided therein, as indicated by the shaded area 26, when the beam is in an unloaded condition.
  • FIG. 3 illustrates a preferred method for making the cast aluminum head 14 of FIG. 2.
  • a concave annular fillet 24a is formed at the junction between the cylindri cal surface 17 and the retaining surface 18 of the head on a radius having a dimension in excess of that desired for the finished dimension of the radius of the fillet 24 of FIG. 2.
  • a compressive force is applied to the annular fillet surface 24a to reduce the dimension of the radius thereof to the desired finished radius of the fillet 24 and to thereby create the residual compressive stress in the area 26.
  • the application of compressive force to the fillet surface 24a is performed by employing a roller 28 having a convex peripheral profile 30 formed on a radius having a dimension conforming to the desired finished radius of the fillet 24.
  • the roller 28 is also provided with marginal portions 32 and 34 bordering the convex peripheral profile 30 thereof, which marginal portions are at right angles to each other.
  • the marginal portions 32 and 34 on the periphery of the roller 28 eventually engage the retaining surface 18 and the cylindrical surface 17 of the head, respectively, thus limiting the action of the compressive force applied to the arcuate fillet 24a and insuring that the fillet is rolled to the desired finished radius.
  • the cut fillet showed plus 6170 micro-strain, the rolled fillet plus 5650 micro-strain, or 520 micro-strain less.
  • the peak fillet strain at rest after 150,000 pounds load, or the zero shift showed the cut fillet with plus 1303 micro-strain, the rolled fillet plus 149 micro-strain, or an 88.6 percent reduction in the zero shift.
  • the failure load for the cut fillet was 284,000 pounds, for the rolled fillet 370,000 pounds or a 30 percent increase in strength. Peak fillet strain at failure for the cut fillet was 18,750 micro-strain, for the rolled fillet 24,000 microstrain or an increase of 5250 micro-strain.
  • a textile beam or spool comprising a cylindrical barrel whose axis defines the beam axis, and a head secured to each end ofthe barrel, each head having a hub with a cylindrical surface extending axially of the beam is in an unloaded condition, said residual compres-.
  • sive stress being localized in that portion of the cast aluminum material which forms said annular concave surface.
  • a head for a textile beam or spool said head having a hub with a cylindrical surface, a retaining surface extending radially outward from said cylindrical surface, and a concave annular fillet at the junction between said cylindrical and retaining surfaces; wherein the material of said head is provided with a residual compressive stress which is localized at said concave annular fillet.
  • a head according to claim 3 wherein said residual compressive stress is on the order of 25,000 pounds per UNITED STATES PATENT OFFICE CERTIFICATE OF CORRECTION PATENT NO. 3,913,863
