A hydrostatic bearing design employing inherently compensated orifices
whose geometric design is such that the use of multiple orifices is
substantially simplified. In normal cylindrical hydrostatic bearings, the
orifices are usually employed in rows. There can be from three to 120
orifices per row, and usually from one to six rows in most designs. In
these designs, the orifice is usually a separate component, which is
pressed into the surface that constitutes the bearing. Inherently
compensated orifices are comprised of three sections, i.e. the entrance
section, the restricting orifice section, and the exit section. The first
two of these sections are of circular cross section. This design employs
slots versus cylindrical type of construction, thereby giving square or
rectangular cross sections. The manufacturing of this type of hydrostatic
bearing is greatly simplified since only three or slightly more parts are
required, versus a separate part for each orifice. Various details are
described with respect to the various structures illustrated. This design
can be used not only with the typical cylindrical type bearing, but also
can be utilized in flat and conical bearing geometries.
