In response to the problem of lubrication failure of sliding bearings in circular arc gear pumps under variable operating conditions, this paper studies the lubrication characteristics of sliding bearings. Establish a fluid lubrication model for sliding bearings and introduce radial forces and Reynolds boundary conditions. Analyzing the influence of rotational speed and outlet pressure of circular arc gear pump on the lubrication characteristics of sliding bearings based on finite difference method. The research results indicate that as the rotational speed increases, the minimum film thickness gradually increases, the maximum film pressure gradually decreases, and the position of the dynamic pressure effect gradually shifts forward. The maximum film pressure position and the minimum film thickness position differ by about 0.4 rad in the circumferential direction. The acceleration curve has a significant impact on the lubrication characteristics of sliding bearings, and the greater the acceleration, the more obvious the changes in lubrication characteristics. Compared with the acceleration process, the changing trend of lubrication characteristics of sliding bearings during the boosting process is opposite.
