| Research Abstract |
The viscosity-temperature characteristic of lubricating oils is often considered as a drawback. The objective of this study is to improve the performance of the journal bearings by inversely using the oil characteristic. The test bearing equipped with the Peltier device and the heater was built and the temperature in the bearing bush was controlled by locally cooling and heating. The temperature distributions were actively developed, so that the film pressure and the bearing eccentricity were changed. Based on both the experimental and theoretical approaches, the possibility to improve the bearing performance was shown.
