Abstract
Abstract A hydrodynamic bearing is disclosed which is designed to work in a fluid. The hydrodynamic bearing is formed with a central section of the load carrying surface that is more compliant so that it will deflect under load and form a pressure pocket of fluid to carry high loads.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
68 words
A hydrodynamic bearing surface comprising a plurality of bearing pads, each bearing pad consisting of a rectangular member with upper and lower surfaces and having peripheral ridges extending above the upper surface of the member, a compliant bearing element affixed to the ridges whereby the element will deflect under lubricant film pressure to form a substantially central depression for formation of a pressure pocket to carry high loads.
Claim 2
Dependent Claim
68 words
A hydrodynamic bearing surface comprising a plurality of bearing pads, each bearing pad consisting of a rectangular member with upper and lower surfaces and having peripheral ridges extending above the upper surface of the member, a compliant bearing element affixed to the ridges whereby the element will deflect under lubricant film pressure to form a substantially central depression for formation of a pressure pocket to carry high loads.
Claim 3
Dependent Claim
15 words
A hydrodynamic bearing surface as in claim 1 where compliant bearing element is an elastomer.
Claim 4
Dependent Claim
16 words
A hydrodynamic bearing surface as in claim 1 where compliant bearing element is a thin foil.
Claim 5
Dependent Claim
18 words
A hydrodynamic bearing surface as in claim 3 wherein the central depression is filled with a soft elastomer.
