Abstract: One embodiment includes a gear pump with a driven gear, a gear shaft passing through the driven gear, and a stationary journal bearing. Also included is a fluid film, between a surface of the stationary journal bearing and a surface of the gear shaft, and a hybrid pad on the stationary journal bearing. The hybrid pad has a minimum leading edge angular location on the stationary journal bearing of 41.5° and a maximum trailing edge angular location on the stationary 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.

Abstract: 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.

Abstract translation: 一个实施例包括具有从动齿轮的齿轮泵，通过从动齿轮的齿轮轴和加压轴颈轴承。 还包括流体膜，在加压轴颈轴承的表面和齿轮轴的表面之间，以及在加压轴颈轴承上的混合垫。 混合垫片在加载的轴承轴承41.5°上具有最小的前缘角位置，并且在54.5°的加载轴承轴承上具有最大后缘角位置。 齿轮泵还包括用于将高压流体从齿轮泵的排出口供给到混合垫片处的流体膜的输送路径。
