Abstract
An active/self-sensing compensating hydrostatic bearing is disposed between first and second structures to allow relative movement between the first and second structures. The hydrostatic bearing includes a body and a compensator. The body, fixed to the first structure and separated from the second structure by a first gap, has a chamber and an input passage and an output passage both communicating with the chamber. The compensator is disposed in the chamber. A compensating passage, communicating with the input passage and the output passage, is formed between the body and the compensator. A pressurized fluid flows from the input passage to the output passage through the compensating passage, and the pressurized fluid in the output passage flows to the first gap to maintain the stability and the rigidity for the relative movement between the first and second structures. A hydrostatic bearing module using the hydrostatic bearing is also disclosed.
