  • Each of the abrasive Segments has attached 58 Field 61 Search 51/206.4 206.5 207 thereto a holding Phite which is held against the flange by a clamping ring.
  • the clamping ring has an outer pe riphery equal to that of the flange, but has an inner [56] References Cited periphery spaced from the supporting body.
  • Each of the holding plates has a projection which extends into UNITED STATES PATENTS such space and contacts the inner periphery of the 1,697,505 1/1929 Hyde 51/2065 clamping ring 1,734,012 10/1929 Jeppson.... 3,633,637 H1972 Kolesh 83/840 4 Claims, 4 Drawing Figures PATENTED JAN 3 4 I975 Fig. I
  • the present invention is concerned with a segmental grinding wheel, in particular an abrasive cut-off wheel, the supporting body of which on one edge of the circular or polygonal periphery thereof is provided with a radially extending flange for aligning the segments forming an abrasive ring and a clamping ring coinciding with the flange, the clamping ring being secured to the flange by means of screws and each abrasive segment being form-closedly locked in radial direction.
  • the actual supporting body, the holding plates of the segments and the clamping ring are held together and locked by means of screws, pins or the like.
  • FIG. 1 is a perspective view of a segmental cut-off wheel with a supporting body according to the invention
  • FIG. 2 is a section along line 1-1 of FIG. 1 and FIGS. 3 and 4 are sections of further examples of the holding plates.
  • Supporting body 1 on one edge of the periphery thereof, is provided with a flange 25.
  • Clamping ring 23 coincides with flange 25, but is narrower than the latter. That is to say, the outer periphery or ring 23 equals that of flange 25, while the inner annular surface 26 thereof is spaced from lower annular surface 27 of supporting body I of interstice A.
  • Holding plates 3 of segments 2 on the lower portion thereof are provided with projections 28, passing beneath the inner annular surface of clamping ring 23 and resting thereon under the action of centrifugal force during use of the grinding wheel.
  • projections 28 may be produced by welding a flange on to the holding plates (FIG. 2) or by bending the lower border thereof FIGS. 3 and 4). It may, however, be readily understood that other constructions are also possible.
  • the number of screws 11 need be chosen only in view ofthe fixation of clamping ring 23, it being, however, advantageous if there is provided one screw 11 per segment 2 to prevent a shifting of segments 2 under the action of tangential forces during use of the grinding wheel.
  • a segmental grinding wheel in particular an abrasive cut-off wheel, of the type including a supporting body and a plurality of abrasive segments supported to extend from the periphery of said supporting body, the improvement comprising:
  • said supporting body having at one edge of the outer periphery thereof a radially outwardly extending flange;
  • each of said segments having attached thereto a holding plate with a first side thereof abutted against said flange, each of said holding plates having an inner end with a projection extending therefrom in a direction away from said flange and parallel to the longitudinal axis of said grinding wheel;
  • a clamping ring abutted against second sides of said holding plates, said clamping ring having an outer annular surface of the same diameter as that of said flange, said clamping ring having an inner annular surface spaced from the outer periphery of said supporting body, said projections of said holding plates extending between said inner annular surface of said clamping ring and said outer periphery of said supporting body.
  • each of said projections comprises a flange rigidly at tached to the respective holding plate.
  • each of said projections comprises an integral portion of the respective holding plate, bent outwardly therefrom.
