ASME B5.35:1983 pdf free download Machine Mounting Specifications for A,brasive Discs and Plate Mounted Wheels
1 PURPOSE To provide standards to be used in the design of machine face plates matching the location of nuts, washers, studs of abrasive discs, or plain or tapped holes of plate mounted wheels.
2 SCOPE This Standard covers ANSI Standard practice for location and size of bolt holes for mounting abrasive discs and plate mounted wheels.
3 GENERAL
3.1 Abrasive discs are bonded abrasives which are molded with inserted nuts, inserted washers, project- ing studs, or a tapped mounting plate on the mount- ing side of the abrasive disc. The nuts, washers, studs, or tapped holes are located in a pattern to match the spacing of corresponding holes in the machine face plate.
3.2 For standar diameters and minimum thick- nesses of steel disc wheels, see Table 1.
3.3 Inserted nut type discs (see Fig. 1.1) are those having threaded nuts anchored in the mounting side of the disc which are located in a pattern to match the spacing of corresponding holes in the machine face plate (see Fig. 1.2).
3.4 Inserted washer type discs (see Table 2 and Fig. 2) are those having washers anchored in the mounting side of the disc which are located in. a pattern to match the corresponding holes in the machine face plate.
3.5 Tapped mounting plate type discs (see Table 3 and Fig. 3) are those having a mounting plate cemented to the mounting side of the disc which has tapped holes located in a pattern to match the cor- responding holes in the machine face plate.
3.6 Projecting stud type discs (see Table 4 and Fig. 4) are those having studs enclosed in the mount- ing side of the disc which are located in a pattern to match the corresponding holes in the machine face plate.
3.7 Cylinder type discs (see Table 5 and Fig. 5) are similar in shape to Type 2 abrasive wheels. Mounting may be by means of inserted nuts, projecting studs, or tapped mounting plate. The mounting means are located in a pattern to match the corresponding holes in the machine face plate. 3.8 Plate mounted wheels (see Tables 6 and Fig. 6) are bonded abrasives having mounting plates of steel or other rigid material cemented to the mounting side of the wheel which has mounting holes located in a pattern to match corresponding holes in the machine face plate. The mounting holes are always located within the inside diameter of the abrasive section. Grinding is done on the exposed flat side.
4 STANDARD HOLE SPACING FOR STEEL WHEELS (MACHINE FACE PLATES) FOR 10 in. TO 30 in. DIAMETER ABRASIVE DISCS See ANSI B7.1, American National Standard Safety Requirements for the Use, Care, and Protection of Abrasive Wheels, Table 2, Minimum Thickness of Machine Face Plates (Steel Disc Wheels) for Mounting Abrasive Discs.
4.1 For 10 in. to 30 in. diameter discs, see Figs. 7,8, and 9.
4.1.1 Holes on each bolt circle are equally spaced.
4.1.2 Holes in steel wheels are 0.386 in. in diameter.
4.2 For 36 in. and 40 in. diameter discs, see Figs.10 and 11.
4.2.1 Holes in steel wheels are 0.386 in. in diameter.
4.3 For 42 in. to 72 in. diameter discs, see Figs. 12,13, 14, and 15.
4.3.1 Holes in steel wheels are 0.386 in. in diameter.
