Abstract
Disclosed herein is an apparatus that includes a fluid dynamic bearing defined in a gap between an inner component and an outer component. In some instances, the inner component and the outer component are configured for relative rotation. In some instances, the apparatus further includes a fluid reservoir configured to supply a fluid to the fluid dynamic bearing and the fluid reservoir is defined by shearless surfaces.
Claims20
An apparatus comprising:
- a stationary component;
- a rotatable component;
- a fluid dynamic bearing defined in a gap between the stationary component and the rotatable component, wherein the stationary component and the rotatable component are configured for relative rotation;
- and
- a fluid reservoir in the stationary component or the rotatable component, wherein the fluid reservoir is bounded by surfaces that are stationary with respect to one another.
