COMBINED SUPPORT Russian patent published in 2015 - IPC F16C21/00 

FIELD: machine building.

SUBSTANCE: combined support contains casing with installed in it journal bearing, roll bearing, its internal cage is installed fixedly, with concentrically located in the journal bearing shaft tail, as well as movable shoe secured with possibility of movement in slots. The slots are on the internal surface of the casing, the roll bearing is installed concentrically on the shaft, at that the internal cage of the roll bearing is fixedly installed on the shaft, the movable shoes are installed with possibility of movement under action of the transverse deformations of the piezoelements of the piezoelectric drive, installed in slots of the casing and connected to the voltage source.

EFFECT: increased reliability of rotor-support system, improved dynamic characteristics of the support at start-up-shutdown modes, assurance of the rotor rotation at start-up modes with use of the roll bearing with its decommissioning by change of the voltage applied to the piezoelements at the set speed of rotation.
