STATIONARY BEARING OF A DRIVE GEAR OF A GEAR PUMP

摘要

One embodiment includes a gear pump with a drive gear 18, a gear shaft 32 passing through the drive gear, and a stationary journal bearing 34. Also included is a fluid film location annularly between a surface of the stationary journal bearing and a surface of the gear shaft, and a hybrid pad location on the stationary journal bearing adjacent the fluid film location. The hybrid pad has a minimum leading edge angular location on the stationary journal bearing of 31.0° and a maximum trailing edge angular location on the stationary journal bearing of 43.0°. The gear pump also includes a porting path 48 for supplying high pressure fluid from a discharge of the gear pump to the fluid film at the hybrid pad.
