Mixed and fluid film lubrication characteristics of hydrostatic spherical bearings for hydraulic piston pumps and motors are studied theoretically under unsteady state conditions. The basic equations considering interference and contact of surface roughness are developed using the mixed lubrication model based on the GW and PC models. The effects of the operating conditions and the bearing dimension on the motion of the sphere, asperity-contact/fluid pressure distributions, leakage flow rate, power loss and the stiffness are examined. A seat geometry which reduces the asperity-contact pressure is presented. A simplified model applicable to the limited conditions in the fluid film lubrication is also derived.
