Abstract
The application of bearing technology in the field of intelligent equipment and special robots continues to promote technological innovation and industrial upgrading, such as the improvement of bearing materials and the development of intelligent bearings, which helps to improve the performance and operation efficiency of equipment. In this paper, the model of dynamic and static pressure tilting pad journal bearing is established, and the influence of eccentricity and preload on the static characteristics of dynamic and static pressure tilting pad journal bearing is studied. The results show that along the rotation direction of the journal, the oil film thickness decreases gradually, the static pressure of the pad increases gradually, and the lower pad is the main bearing pad; With the increase of eccentricity and preload coefficient, the bearing load coefficient and friction coefficient also increase.
