Abstract
A ring support system for use in a variable pipe diffuser. The ring support mechanism includes at least three axle shafts and at least three roller bearings rotatably mounted to the axle shafts, an inner ring having a groove disposed in the outside diameter, and an outer ring having a corresponding groove disposed in the inside diameter. The at least three axle shafts are circumferentially mounted in the outer ring such that the rollers are positioned partially within the groove of the outer cylinder such that the roller bearings define a diameter nearly equal to the outside diameter of the inner ring. The inner ring is positioned within the at least three roller bearings such that the at least three roller bearings are in axial sliding contact with the groove of the inner ring and in rolling contact with the groove of the inner ring. The ring support system provides rotational and axial support of the inner ring.
