Abstract:
The performance of a porous-ceramic hydrostatic journal bearing manufactured by
the starch consolidation (SC) technique has been examined using a highly instrumented test rig.
The results have been compared with those of a 5-recess hydrostatic bearing of the same size and
comparable design, under the same testing conditions. The SC porous-ceramic bearing showed
an improved performance over the conventional hydrostatic bearing. Static and rotational stiffness
were 95 per cent and over 150 per cent higher, respectively. In addition, the porous ceramic
bearing exhibited a more economic performance with a 64 per cent lower flowrate and pumping
power than the hydrostatic bearing. In terms of heat generation, the porous ceramic bearing
showed 50 per cent lower temperature rise
