COMBINATION BEARING SUPPORT Russian patent published in 2008 - IPC F16C21/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly to production of rotary-bearing supports made up of a combination of a plain and anti-friction bearings increasing the reliability and life of rotary machines. The combination bearing support consists of an anti-friction bearing and a plain beating with a tapered bearing surface fitted on the shaft. The shaft accommodates also an unequal-rigidity ring fitted to get deformed in radial direction, i.e. to have outer diameter varied under centrifugal force effect, to ensure a friction contact with the plain bearing movable tapered bushing. Note that the said ring is a corrugated one furnished with recesses and ledges, the former being designed to rigidly fix the ring on the shaft and the latter accommodating the weights.

EFFECT: higher reliability and longer life, easier manufacturability and operation.
