Paper Title:
Numerical Analysis on Hybrid High Speed Sleeve Bearing
  Abstract

Hybrid sleeve bearing is widely used in high speed principal axis system. Numerical analysis on a spiral oil wedges hybrid sleeve bearing of high speed principal axis is investigated in this paper. The finite differential equations of Reynolds, film thickness and velocity in an oblique coordinate system are obtained. By means of the finite differential method, loading capacity, pressure distribution, and stream of lubricating oil of the hybrid sleeve bearing are computed and analyzed. The results show that spiral oil wedges can produce the flow separation between hot oil and cold oil, and avoid the oil heated repeatedly. With the increase of eccentricity and decrease of spiral angle, the loading capacity of the bearing increases.
