METHOD OF TECHNICAL STATE DIAGNOSTICS OF WHEELSPACE BEARING OF TWO SHAFT GAS TURBINE ENGINE Russian patent published in 2015 - IPC G01M15/14 G01M13/04

Abstract RU 2537669 C1

FIELD: motors and pumps.

SUBSTANCE: vibration transmitter is installed on the vibration line fixed in the inspection window of the front part of the work blades of HP turbine being isolated from the engine body. The vibration line is installed in rest to the blade flange of HP turbine near the inspected bearing, pressing force is regulated by the damper spring. To estimate vibration amplitude generated by the wheelspace bearing the LP rotor is spinned up using the hand drive to speed 60-100 rpm. Peak factor is determined, and conclusion is made on technical state of the wheelspace bearing.

EFFECT: increased result authenticity during estimation of the technical state of wheelspace bearing.
