Embodiment Construction
[0069] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0070] Such as Figure 7 As shown, the content of the static and dynamic performance design method of the high-speed water-lubricated dynamic pressure spiral groove thrust bearing of this embodiment is given, which mainly includes the following steps:
[0071] s1: Considering the coupling effects of multiple factors such as cavitation effect, centrifugal effect, turbulent flow effect and thermal effect, a closed high-speed water-lubricated dynamic pressure spiral groove thrust bearing lubrication model is established:
[0072] The geometric structure of the closed high-speed water-lubricated dynamic pressure spiral groove thrust bearing is as follows: figure 1 As shown, the thrust bearing is composed of two opposite fixed thrust pads and a clockwise rotating thrust disk; the upper and lower working surfaces of the thrust disk are engraved with peri...
