ABSTRACT OF THE DISCLOSURE A hub assembly 30 for releasably mounting a circular grinding wheel 18 on a rotatable shaft 14 is disclosed. The assembly 30 includes a hub 36 having a radially extending face 42 to engage one major side surface of the grinding wheel. A central axially extending surface 122 on the hub engages a central passage 120 through the, grinding wheel 18 to center the grinding wheel relative to the hub. An annular flange or clamp member 40 has an opposing radially extending face 44 which clamps the grinding wheel against the hub. The flange is centered relative to the hub by an axially extending surface 132 which engages the central passage through the grinding wheel. The flange includes a plurality of slots 70-84 through which the screws 50-64 extend. The heads of the screws may pass through wide portion 90 of the slots, but they cannot pass through narrow portions 96. The flange may be rotated between a disengaged position and an engaged position. In the disengaged position, the heads of the screws are aligned with the wide portions of the slots to enable the flange to be removed. In the engaged position, the heads of the screws are aligned with the narrow portions of the slots to permit the flange to be clamped against the grinding wheel. A cover plate 150 covers the outside of the slots. Holes are formed in the plate to provide access to the screws.
