FIELD: devices for fastening of grinding wheels, applicable in high-velocity grinding in mechanical engineering. SUBSTANCE: device for fastening of grinding wheel has adapter flange 1 and pressing-down flange 2 interconnected by means of screws 3 through spherical split ring 4 and washer 5 with gasket 6, and grinding wheel is clamped and installed. Grinding wheel during assembly, first, is based on flexible member 10 and balanced with the aid of weights 11. Made on pressing-down flange and grinding wheel are spherical bands which in assembly provide for tension through spherical split ring to unload the grinding wheel from centrifugal forces. EFFECT: device for fastening of grinding wheel allows compensation of loss of grinding efficiency due to reduced diameter of grinding wheel, as it wears out by turning washer relative to adapter flange to increase in this manner the width of grinding due to increased amplitude of variation of zone of contact of grinding wheel with blank. |
