ABSTRACT:
An axial thrust sliding bearing is provided for a shaft-driven centrifugal fluid handling machine which provides non-contact accommodation of axial thrust loads, self-pressurized lubrication, and improved wear resistance. A shaft is journaled within a stationary bearing support sleeve and has an opposed bearing ring disc secured to the shaft for rotation therewith. The sleeve and the disc each have spaced apart, facing front end surfaces angled with respct to the axial center line of the shaft so that during rotation of the shaft and of the bearing ring disc secured thereto, the front end surface of the bearing ring disc is moved toward and away from a fixed point on the front end surface of the stationary bearing support sleeve, thereby providing a pumping action on a lubricating fluid contained between the two surfaces.
