A bidirectional radial bearing for rotatably supporting a rotor or shaft may include a bushing with an interior bore having one or more antirotation retainers that may be equally spaced and extend the axial length of the interior bore. The interior bore of the bushing may be formed into a plurality of lobes. The interface of adjacent lobes and a compliant foil and a foil underspring form symmetrical converging wedges. The combination of the lobed bore and the compliant foil and foil underspring establish symmetrical converging wedges surrounding the rotor or shaft. In another aspect of the present invention, a single compliant foil may combine with the lobed bore and one or more foil undersprings to form two or more symmetrical converging wedges. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. |
