According to different loads, a hydrodynamic bearing may be journal hydrodynamic bearing thrust hydrodynamic bearing.
A journal hydrodynamic bearing maybe designed with varous structures, including three-oil wedge bearing, step-face bearing, tilt pad bearing etc.
Three-oil wedge bearings and step-face are fixed pad multi wedge bearing. During operation many hydrodyanmic oil films are formed, with good rotary accuracy, self-alignment, high rigidity and damping, better high speed stability. They are commonly used for high speed light load bearing.
Tilt pad bearing are tilting multi-oil wedge bearings, of which pads may be automatically adjusted for inclination with varied load and speed. There are one of the bearings with stability and mainly used for high speed and light load bearing.
A thrust dynamic bearing maybe designed with various structures, including fixed-pad inclined thrust bearing, fixed pad inclined-planar thrust bearing, fixed- pad step-face thrust bearing, tilt-pad thrust bearing, etc.
Fixed-pad inclined thrust bearings, fixed-pad inclined-planar thrust bearings, fixed pad step-face thrust bearings are fixed-pad thrust bearing and the main form of thrust plain bearings. They apply to medium and small-scale light-load thrust plain bearings.
Tilting-pad thrust bearings apply to important large and medium scale thrust plain bearings.
