GEAR PUMP DRIVEN GEAR PRESSURE LOADED BEARING |
| 摘要 |
One embodiment includes a gear pump with a driven gear, a gear shaft passing through the driven gear, and a pressure loaded journal bearing. Also included is a fluid film, between a surface of the pressure loaded journal bearing and a surface of the gear shaft, and a hybrid pad on the pressure loaded journal bearing. The hybrid pad has a minimum leading edge angular location on the pressure loaded journal bearing of 41.5° and a maximum trailing edge angular location on the pressure loaded journal bearing of 54.5°. The gear pump also includes a porting path for supplying high pressure fluid from a discharge of the gear pump to the fluid film at the hybrid pad. |
