Abstract

1,049,995. Grinding. ATLAS COPCO A.B. Nov. 3, 1965 [Nov. 17, 1964], No. 46557/65. Heading B3D. A holder for an abrasive disc 2 comprises a rotatable drive shaft 1, a first layer of resilient material 10 having an annular rim portion coaxial with the shaft arid disposed in a plane 11 perpendicular thereto, the layer having a central recess facing the plane, a second resilient layer 12 fixed to the surface of the first layer on the side opposite the plane, means connecting the central portions of the layers to the shaft, and locking means within the recess for locking an abrasive disc on the shaft so as to be supported by the first layer, the second layer being formed of a material having greater capacity to stretch under centrifugal action than the first layer so that centrifugal displacement of the first layer tending to diminish the recess is counteracted by centrifugal stretching of the second layer. The shaft 1 has a threaded end 4 which receives a hub 3 formed with a flange 6. The first resilient layer, which may be of natural rubber, is vulcanized to the flange and a part of the outer surface 9 of the hub, and the second resilient layer, which may also be of natural rubber, is vulcanized to the first layer and to a further part of the surface 9 of the hub. An annulus 13 of woven material may be vulcanized between the layers to reinforce the holder. The locking means is in the form of a nut 7 which is received within the recess behind the plane 11 containing the outer annular rim of the first layer, and the abrasive disc 2 is locked between the flange 6 on the hub and a flange 8 on the nut. The first layer 10 has a Shore durometer hardness of 90-95, preferably 10-20% higher than the hardness of the second layer which may have a Shore durometer hardness of 80-85.
