COMBINED HYBRID SUPPORT Russian patent published in 2009 - IPC F16C21/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering, namely to rotor-support unit production. Combined hybrid support comprises a housing and a bush of hydrostatic/hydrodynamic sliding bearing. The bush is set in the housing and can be moved axially; a closed cavity supplied with the operating fluid under pressure is formed by the bush and the housing. The bush inner surface comprises two parts: one is characterised by mating conical multilobe surface embracing a shaft conical journal, the other one - by mating cylindrical surface on the shaft. On the cylindrical surface side the bush is applicated with an axial application spring in respect to the shaft, the spring force value is less and its direction is opposite in relation to the force developed in the above closed cavity and affecting the bush. A system of supplying operating fluid to the running clearances of the hydrostatic/hydrodynamic sliding bearing is formed in the housing and the bush; it consists of feeding pipes, gasket rings and a jet.

EFFECT: increasing reliability and service life of the rotor-support unit, simplifying its production and operation due to simple design, increasing operation resource, motion stability and suppressing shafts and rotors whipping.
