Abstract
An operating shaft which provides compensation axial and spatial misalignment between a rotatable component mounted within an enclosure and a rotating device generally outside the enclosure. The operating shaft has a first end which is dimensioned to be slidably received within a receiving portion of the rotating device such that the shaft is maintained in a fixed angular position with respect to the rotating device. The shaft is axially slidable with respect to the rotating device such that it will provide compensation for axial misalignment between the rotatable component and the rotating device. The shaft has a second end formed to engage the rotatable component such that an rotation of the rotating device will produce a corresponding rotation of the rotatable component. The shaft also has a spatial compensation device which is integrally formed in the shaft between its first and second ends. The spatial compensation device provides compensation for spatial misalignment between the axis of the rotatable component and the axis of the rotatable device. This is accomplished by creating a compensating angle between the first and second ends which permits the shaft to be rotated about its axis while maintaining the compensating angle.
