HYDROSTATIC BEARING Russian patent published in 2007 - IPC F16C32/06 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in radial-and-thrust supports of spindle units of metal-cutting machine tools. Proposed hydrostatic bearing has housing with ring and radial channels, shaft and movable bushing with radial channels. Bushing is found in space between housing and shaft. Radial channel in housing in made in form of throttling holes arranged over circumference or slot throttling clearance and it connects ring channel with step slot throttling clearance. Radial channels in bushing are made throttling.

EFFECT: reduced power losses at delivery of lubricant, no negative compliance both in radial and axial directions, increased load-bearing capacity of hydrostatic bearing.
