Analysis of the Contact Stresses in Curvic Couplings of Gas Turbine in a Blade-Off Event

摘要

The curvic couplings are the important components of a gas turbine widely used in the aero-engine and electric power generation industry to drive rotating equipment and safely transfer high torque without relying on friction between the contacting surfaces of the curvic couplings. Its advantages such as reliable location, precise centring ability, excellent structural stability, strong load bearing ability definitely make the curvic couplings used more and more widely in the high speed rotating machine for torque transmission.
