Abstract

912,135. Centrifugal blowers. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 3, 1959 [July 4, 1958], No. 22909/59. Class 110(1). In a centrifugal compressor the rotor unit is internally supported by bearings fast with a fixed shaft, and the distance between the bearings is equal to or less than the distance between the axial limits of sealing means provided between a radially outwardly directed surface of the unit and a surface of the casing. A bladed impeller 3 is keyed to a hollow shaft 9 and at one end of the shaft is formed peripheral toothing 10 which engages a gear train. A fixed shaft 18 has a duct 19 which supplies oil under pressure to bearings 16 and 17. Fluid-tight packings 23 and 24 are disposed between the casing 5 and the shaft 9 and may extend the full length of the shaft on either side of the impeller 3. The impeller may be double-sided and a second intake provided. Since the bearings 16 and 17 are concentric with the fluid-tight packings 23 and 17 they are set close together forming a rigid structure and at the same time providing a large bearing surface with adequate packing against the admission of air or lubricant.
