Definitions

  • various reinforcing techniques have heretofore been used or These techniques include the embedding of metallic rings, fabrics of various compositions, haphazardly arranged textile and glass fibers, and short lengths of metal fibers known as metal wool in the abrasive material to increase the strength thereof.
  • the various reinforcing elements heretofore employed in grinding wheels are spaced a substantial distance from the peripheral surface of the wheel to prevent their exposure at the grinding surface in order to avoid interference with the grinding action thereof.
  • the rings are disposed contiguous to the hole or arbor through the center of the grinding wheel and the remaining portion of the wheel extending radially therefrom is unreinforced.
  • the portion of the abrasive wheel disposed inwardly of the ring is subjected to a stress which is substantially purely tangential, whereas the stresses adjacent to the periphery of the ring are substantially purely radial.
  • U-shaped reinforcing elements 54 are mechanically interlocked such as by wrapping or twisting around the reinforcing ring 40 and are extended radially outwardly therefrom having the ends thereof securely held by the clamps 150 in appropriate radially projecting relationship.
  • the reinforcing elements 54 and the reinforcing ring 40 can thereafter be sprayed or brushed with a suitable adhesive securely attaching the reinforcing element to the ring forming therewith a unitary reinforcing network which can be simply handled and be positioned in the mold for forming the grinding wheel.
  • Adhesives suitable for this purpose are well known in the art and can comprise bonding agents such as epoxy, polyester, and phenolic resins, for example.
  • the points of contact between the reinforcing element 54 and the ring 40 can be rigidly secured to each other by means of tack welding, brazing, soldering and the like, as desired.
  • reinforcing elements comprise crimped high strength steel wire having a cross sectional area equivalent to a circular wire of a diameter ranging from about 0.030 to about 0.130 inch and an ultimate tensile strength of at least about 200,000 p.s.i.
