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 translation: 卡盘（A）夹紧轮毂组件（B）的壳体（2）以使其快速握住并进一步接合在壳体内的轮毂心轴（20），并且将心轴旋转在位于其之间的轴承（6）上 和壳体，使得可以精确地加工轮毂（4）上的凸缘（10）。 卡盘包括固定基座（76），该固定基座（76）承载夹持在壳体上以夹紧外壳的夹爪（114）。 它还包括由可旋转底座承载的可旋转底座（124）和心轴（164），并与轮毂的主轴接合以使轮毂旋转。 心轴可以相对于旋转底座径向移动，以适应轮毂和旋转底座的旋转轴线之间的未对准。 轴承（188）位于心轴和旋转底座之间，以抵抗施加到心轴的轴向力，以使其在轮毂心轴中膨胀。
