Vane pump with tilting pad radial bearings

A vane pump comprises: a drive shaft that passes through the pump frame; a rotor coupled to the drive shaft that has multiple vanes and rotates within the pump frame in an axial direction about an axis of rotation with an outer rotor surface that has a radius that extends from the axis of rotation;...

Beschreibung
Zusammenfassung:	A vane pump comprises: a drive shaft that passes through the pump frame; a rotor coupled to the drive shaft that has multiple vanes and rotates within the pump frame in an axial direction about an axis of rotation with an outer rotor surface that has a radius that extends from the axis of rotation; a cam ring within the pump frame that circumscribes the rotor and vanes with a cam ring inner surface; multiple radial tilting pad bearings that support the cam ring; a bearing support ring coupled to the pump frame that generally circumscribes the cam ring and mounts the radial tilting pad bearings; side plates that radially extend from the drive shaft to the pump frame to enclose the rotor and the cam ring with at least one side plate having an inlet port and an outlet port; and means for initiating rotation of the cam ring from rest.
