Abstract
An improved hub assembly is utilized to rotatably mount a grinding wheel. The hub assembly includes a hub which engages a first major side surface of the grinding wheel. A circular clamp member is mounted on the hub by a plurality of fasteners. An annular flange ring circumscribes the clamp member and engages a second major side surface of the grinding wheel. The clamp member has radially extending arms which engage the flange ring and press it against the grinding wheel. A cover is mounted on the flange ring and extends over the fasteners. When the grinding wheel is to be removed from the hub assembly, the fasteners are loosened by inserting a suitable tool though openings in the cover. Loosening the fasteners enables the annular flange ring to be rotated relative to the clamp member until the radially extending arms on the clamp member are aligned with radially extending recesses formed inside the flange ring. The flange ring can then be moved axially outwardly away from the grinding wheel and the clamp member.
