【 摘 要 】

The purpose of this paper is to show the results of parametric experiments about the thermohydrodynamic performance of the steady-state loaded hole-entry hybrid bearing. Because there are many available theoretical in that respect have been studied, it become an urgent need to do related experimental researches. In the present study, the internal pressure and temperature distribution, flow rate and shaft center position under different supply pressures were measured. At the same time, a series of tests under different load and speed conditions were conducted. The experimental results show that bearing performances are significantly affected by the temperature rise of oil film, meanwhile, speed is the most important factor affecting the bearing temperature distribution.
