POWER TRANSMISSION SYSTEM, TURBOMACHINE AND POWER TRANSMISSION METHOD Russian patent published in 2018 - IPC F01D25/16 F02C7/32 F02C7/36 

FIELD: machine engineering.

SUBSTANCE: power transmission system for the turbomachine comprises a transmission shaft connected to engine shaft by connection means and actuates equipment or auxiliary means. The transmission shaft is configured for operating in supercritical mode and comprises means for damping vibrations at its resonant speed. Damping means are mounted on radially outer end of the shaft and arranged in removable casing. When transmitting power to the equipment or auxiliary means, the transmission shaft is rotated at the supercritical speed and vibrations are dampened during its operation at its resonance speed by the damping means. Another invention of the group relates to the turbomachine comprising said system.

EFFECT: reduced size of the turbomachine transmission shaft and simplified maintenance.
