Paper Abstract
In order to enhance the measuring accuracy of angular displacement, it is important to form high accuracy and superior quality of moire fringe signals. They are strongly affected by the radial disturbance of grating disk which is mounted on the shaft of bearing system. Specifications for the hydrodynamic bearing system often call for much higher radial accuracy and stability. This requirement poses unique challenges for the design of the bearing system. In this paper, the design of precision three-lobe hydrodynamic bearings is described, and lubricant performance of some structure parameters is analyzed. The radial accuracy of this bearing system is within 0.023 micrometers .
