Abstract:
A press-fit thrust bearing system and apparatus. A press-fit thrust bearing for an electric submersible pump includes a protruding band extending around a midsection of a bushing, the protruding band extending inward towards a drive shaft, outward towards a diffuser, or both. When extending outwardly, the band is press-fit into the diffuser to prevent dislodgment of the bushing. A non-rotating guide sleeve extends around the bushing above the protruding band, the guide sleeve interlocking with the protruding band to prevent rotation of the bushing. The guide sleeve includes a projection, the protruding band has a channel and the projection mates with the channel to form the interlock. A pair of flanged, rotatable bearing sleeves extend inwards of the single bushing and are keyed to the drive shaft. The top and bottom faces of the bushing serve as thrust handling surfaces.

Claim (Index 14):
A press-fit thrust bearing set comprising:\n at least one rotatable flanged sleeve; a bushing press-fit to a diffuser outward of the at least one rotatable flanged sleeve, the bushing comprising:\n a tubular portion; and \n a protruding band extending circumferentially around at least a portion of an intermediate section of the tubular portion and outward towards the diffuser, the protruding band press-fit to the diffuser; \n a first outer surface portion of the bushing press fit to the diffuser, the first outer surface portion adjacent a first edge of the protruding band and extending towards a first thrust surface of the bushing; a non-rotatable guide sleeve extending circumferentially around a second outer surface portion of the bushing, the second outer surface portion extending from a second edge of the protruding band towards a second thrust surface of the bushing, the guide sleeve pressed between the second outer surface portion of the bushing and the diffuser; and at least one flange of the at least one rotatable flanged sleeves extending over one of the first thrust surface of the bushing, the second thrust surface of the bushing, or a combination thereof.
