Abstract: A chuck (A) grips the housing (2) of a hub assembly (B) to hold it fast and further engages a hub spindle (20) that is within the housing and rotates the spindle on a bearing (6) that is between it and the housing so that a flange (10) on the hub (4) may be machined with precision. The chuck includes a fixed base (76) that carries jaws (114) which clamp down on the housing to firmly hold the housing. It also includes a rotatable base (124) and an arbor (164) carried by the rotatable base and engaged with the spindle of the hub to impart the rotation of the hub. The arbor can shift radially with respect to the rotating base to accommodate misalignment between the axes of rotation for the hub and the rotating base. A bearing (188) lies between the arbor and rotating base to resist an axially directed force applied to the arbor to expand it in the hub spindle.

Abstract: An arbor or chuck assembly for holding a workpiece or tool includes an arbor or chuck body (1, 41) having a linear body portion (1a, 41a) and an expansion or contraction portion (1b, 41b) with inclined faces, a collet (2, 31) positioned radially between the arbor or chuck body (1, 41) and the workpiece or tool for reciprocal movement along a machine axis and having a linear body portion (2a, 31a) and an expansion/contraction portion (2b, 31b) with inclined faces in sliding contact with those of the arbor or chuck body, and a ball bushing (3, 33) provided between the linear surfaces of the collet (2, 31) and arbor or chuck body (1, 41) with a slight interference fit, in order to provide zero clearance and substantially frictionless movement therebetween. Expansion or contraction and release of the arbor or chuck is controlled by a compression spring (4, 34) biasing the moving member in one direction, and a drawbar (12, 42) for pushing the moving member against the spring force in a release direction. The collet may have rubber seals (5, 35) for sealing its slots and apertures from contaminants. A cap (40) mounted on the end of the arbor or chuck body may have a tapered wall which slidingly engages an edge of the moving member as it reaches the end of its travel in the release direction to avoid deformation.
