Abstract
A compliant hydrodynamic fluid film bearing for supporting a rotating motor on a stationary mount, includes a bearing sheet supported by a resilient, compliant support element formed of a series of resilient metal tubular members held in parallel spaced array by a cage. The degree of damping can be selected by filling some or all of the tubes with damping material. The tubular support elements are very strong for their size and weight, and yet produce a support element of only moderate and predictable stiffness.
