FIELD: mechanical engineering.
SUBSTANCE: device has ring-shaped balancing chamber filled fully with low melting point materials being capable of melting in case of melting of support and harden due to natural heat drain as a result of thermal cycle between support and environment. Between rotor and bearing surface a ring-shaped piezoelectric element is mounted, opposite sides of which are connected through resistor. Resistor is placed close to balancing chamber.
EFFECT: higher efficiency.
