Abstract
A hemispherical dynamic pressure bearing includes a supporting shaft, a fixed hemisphere fixed on a first end of the supporting shaft, and a sliding hemisphere slidably disposed on a second end of the supporting shaft. A spring is disposed on the supporting shaft for biasing the sliding hemisphere away from the fixed hemisphere. A bushing has first and second hemispherical grooves in which the fixed and sliding hemispheres are disposed, respectively. A gap adjuster is connected to the shaft for adjusting a gap between each hemisphere and its respective groove. The gap adjuster applies a variable force against the sliding hemisphere to compress the spring.
