Abstract
A fluid-film, pocket bearing of the three axial-groove-type, which has three bearing pads but only two pressure pockets. The design of the bearing provides significant stabilization and a capacity for supporting heavy loads with the predominant pocket loading being horizontal thereof. One of the pads, in the lower half of the bearing, encompasses the location whereat loading thereof obtains, and this one pad has no pressure pocket. The trailing edges of the two pockets (in the other pads) are smoothly blended into the pad surfaces.
Claims24
A fluid-film, pocket bearing, for journaling a rotary shaft, comprising:
- an annulus having inner and outer circumferential surfaces, and an axial center;
- means defining a plurality of bearing pads on said inner surface;
- means communicating said inner and outer surfaces, for admitting fluid to said inner surface;
- and
- relieved pockets formed in said inner surface;
- wherein
- said pockets comprise means for effecting loading of said bearing predominantly horizontally thereof;
- said pockets each have a substantially uniform depth, throughout a substantial cicumferential length thereof, and leading and trailing edges, relative to a rotary direction of a given shaft to be journaled by said bearing;
- one of said edges is defined by diminishing depths which blend commonly into one of said bearing pads;
- and
- the other of said edges is defined by an abrupt, recessed step of said uniform depth.
