Abstract

See full text

A groove is applied to one or more contact surfaces of a journal bearing of a pump to increase a force applied to the contact surface(s). Each groove has an end exposed to discharge pressure of the pump so that the groove communicates the discharge pressure across the contact surface. The groove reduces an area of the contact surface over which fluid leakage results in a pressure differential, thereby increasing a net force applied to the contact surface. Applying the groove to the axial end face of the journal bearing enhances an axial force applied to the journal bearing whereas applying the groove to a radially facing land reduces friction between the journal bearing and the outer housing.
