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

FIELD: machine building.

SUBSTANCE: combined support contains casing, installed in it roll bearing and journal bearing, at that resilient metal plates are secured as one of the support surfaced of the journal bearing at main operation modes and as setting elements during start-shutdown, they create V-shaped clearances. The resilient metal plates are located in the bushing, installed in the internal ring of the journal bearing, and creating V-shaped clearances with shaft. On the casing along the circle the solenoid valves are installed, they are connected to the power source.

EFFECT: increased service life and reliability of system rotor-supports due to separation and redundancy of the functions of roll bearing and journal bearing, and active control of their characteristics at different operation modes of the rotor machine.
