Abstract
A bearing assembly for an electrical motor of an ESP pump assembly comprising an outer bearing sleeve with an inner surface and an anti-rotation device rotationally coupling the outer sleeve to a stator and an inner bearing sleeve with an outer surface and an anti-rotation device coupling the inner bearing sleeve to a drive shaft. A fluid film gap located between the outer surface and the inner surface generates a high pressure zone and a low pressure zone in response to a rotational motion of the inner bearing sleeve relative to the outer bearing sleeve. The high pressure zone generates a fluid exit zone and the low pressure zone generates a fluid inlet zone for the working volume of fluid within the fluid film gap. A fluid supply path with ports at the sides of the bearing can exchange a volume of cooling fluid with the volume of working fluid within the fluid film.
