초록 ▼

A hydrodynamic bearing which includes a carrier and a plurality of bearing pads circumferentially spaced about the carrier. The pads may have a modular construction whereby pad portions are secured to support portions. The pads may also be releasably secured to the carrier. Various bearing pad constructions are contemplated. This includes constructions in which the secondary support portion includes a membrane and the primary support portion includes a cylindrical member extending between the membrane and the bearing pads, relatively rigid constructions in which the necessary deflections are achieved through pad shape and center post configurations and positioning, pads having a wear surface formed therein, and a continuous bearing pad ring may be substituted for the discrete bearing pads. The carrier may be provided with locator pins in the pad receiving bores to orient the pads properly. The carrier may have cuts and grooves formed therein to provide a flexible or even beam mounted support for the bearing pads. The bearing may also have a multimode configuration and may include smart structures.

A modular hydrodynamic bearing adapted to support a rotating shaft, the bearing comprising: a carrier member, the carrier member having a plurality of openings formed therein, the openings being spaced about a predetermined axis; a plurality of bearing pads secured in the openings of the carrier, each of the bearing pads comprising a pad portion having a pad surface a supported surface and at least one edge extending between the pad surface and the supported surface; a support portion having an axis which is perpendicular to the plane of the pad surface and the support portion supporting the pad portion at a location on the supported surface which is spaced from any edge of the pad, and a base supporting the support portion; the support portion having a first end attached to the pad portion at said location spaced from any edge of the pad and a second end attached to the base and a central region between the first and second ends wherein the support portion is curved so as to flare outward toward the first and second ends so that the support portion is wider proximate the first and second ends than it is in the central region and the support portion being symmetrical about its axis such that every section of the support portion lying on a plane transverse to the axis has the same shape.
