SUPPORTING BEARING ASSEMBLY OF CENTRIFUGAL MACHINE Russian patent published in 1999 - IPC

FIELD: compressor engineering, applicable for production of supporting bearing assemblies for shafts of centrifugal machines in compressors, turbo-expanders, pumps, turbines. SUBSTANCE: supporting bearing assembly comprises a shaft neck, body and disks in antifriction bearings installed for engagement with the above neck with the axes of rotation parallel to the axis of the shaft neck; at least the axis of one of the disks is installed in the body for radial movement, for example, due to eccentric arrangement of the mounting surfaces for antifriction bearings relative to the mounting surfaces of the axes directly in the support body. The shaft neck is furnished with a coaxial bush engageable with the disks. The invention provides for independent finishing of the supporting assembly on a separate stand, which facilitates enhanced reliability and economical efficiency of centrifugal machines. EFFECT: no necessity of finishing of turbo-machines in industrial conditions for elimination of the effect of forces caused by specific conditions and place of service. 2 cl, 3 dwg
