- Due to the complex structure, the difficult calculation process of the bearing force and many influence factors of static performance of Water-Lubricated Hydrostatic and Dynamic Hybrid Bearing, the static performance index and influence rule are hardly to be explored and mastered by the engineer, and then it has brought great difficulty to the design of the bearing. Therefore, the paper derives the bearing core equations of single fan-shape ladder-pocket support pad and opposed bearing system, and analyzes the influence law of the design parameters on the static performance of Hydrostatic and Dynamic Hybrid Bearing System regulated by Multi-Head Pump. The result shows that the bearing force is composed of static force and dynamic force, and the dynamic force does not affect the static performance. The bearing capacity increases gradually with the increase of pump pressure and the film thickness, and decreases with the increase of shadow pocket thickness, which has nothing to do with the flow rate and rotational speed. The static stiffness increases gradually with the increase of pump pressure, and decreases with the increase of shadow pocket thickness and film thickness, which has nothing to do with flow rate and rotational speed. The power loss increases gradually with the increase of flow rate, pump pressure and rotational speed, and decreases with the increase of shadow pocket thickness and film thickness. The proposed research provides the theoretical reference for the design and analysis of the Hydrostatic and Dynamic Hybrid Bearing system.
