Abstract
A thrust bearing assembly for a submersible motor assembly of a submersible pump assembly comprising first and second bearing members or plates and first and second bearing holders contained within a housing. Each bearing plate is in the form of a disk having a bearing surface, and the first and second bearing plates are disposed between the first and second bearing holders with the bearing surfaces in face-to-face contact. The first bearing holder is in the form of a thrust bearing holder, and the second bearing holder is in the form of a gimbal plate. The first bearing plate is adapted to rotate with a rotor shaft of the submersible pump assembly and to impose a thrust load on the second plate, and the second bearing plate is adapted to remain stationary relative to the rotating first bearing plate. Grooves are defined by one or both of the bearing surfaces to allow fluid from a fluid supply to enter between the bearing surfaces to create a fluid film to lubricate and cool the bearing surfaces.
