BEARING UNIT FOR CENTRIFUGAL MACHINE Russian patent published in 2001 - IPC

FIELD: manufacture of centrifugal machines; manufacture of carrier thrust bearings for compressors, pumps, turbines, etc. SUBSTANCE: bearing unit has trunnion of shaft and bearing rollers with ridges located circumferentially around shaft trunnion. Rollers and shaft trunnion are so engageable that straight line passing through line of contact of roller and trunnions passes through points of contact of roller ridges and engageable parts of shaft trunnions; this line is parallel to axis of shaft trunnion. Beads of roller may be located on one side from cylindrical surface of contact of roller and shaft trunnion. EFFECT: enhanced radial rigidly; possibility of taking-up reversible axial load at minimum wear, minimum friction losses; enhanced reliability of bearing unit. 2 cl, 3 dwg
