GEAR DETERMINING INHERENT FREQUENCY OF VIBRATION OF BLADES OF GAS-TURBINE ENGINE |
摘要 |
manufacture of engines for flying vehicles. SUBSTANCE: gear anchored on platform has vibration exciter, tune-up device, clamping member of clamping unit to attach blade of gas-turbine engine to bases of lock. Clamping unit with blade is mounted on immobile platform and clamp is loaded by disc springs. Vibration exciter is held on tune-up device in zone of location of blade of gas-turbine engine owing to electromagnetic forces. Body of vibration exciter houses spring and induction coil with core freely moving within limits of 0.5 mm. High-frequency vibrations in range of 600-3000 Hz are excited in tune-up device located in zone of position of blade of gas-turbine engine by means of core through spring. EFFECT: simplified design of gear, reduced consumed power, enhanced productivity and accuracy of measurement of inherent vibrations of blades of gas- turbine engine. 1 dwg
