Abstract:

The temperature of bush inner surface temperature is measured by using infrared thermometer and transparent bearing, and temperature rise is measured by using thermocouple. The influence of rotating speed and axial location on the bush inner surface temperature is studied, and the influence of supply pressure and rotating speed on the temperature rise is analyzed. The results show the bush inner surface temperature and temperature rise of spiral oil wedge hydrodynamic bearing increase with the increase of rotation speed. In axial direction, the temperature is higher around the oil return hole. The temperature rise decreases with the increase of supply pressure. The highest temperature of bush inner surface and temperature rise are higher at higher speed, so the temperature rise is the fundamentalreason which restricts the increase of rotation speed for high speed sleeve bearing.
