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.

润滑油的粘温特性通常被认为是一个缺点。本研究的目的是通过反向利用油的特性来提高滑动轴承的性能。安装了装有珀尔帖装置和加热器的试验轴承，通过局部冷却和加热来控制轴瓦内的温度。温度分布被积极地发展，从而改变了膜压力和轴承偏心。从实验和理论两方面分析了提高轴承性能的可能性。
