Title (EN) GENERATOR WITH RETAINING RING KEY THAT REDUCES ROTOR TOOTH STRESS
(FR) GENERATEUR A CLAVETTE REDUISANT LES CONTRAINTES DE LA DENT D'UN ROTOR
Abstract: front page image
(EN)An electrical generator having a keyway for a retaining ring key formed in only the pole portion of the rotor and not in the tooth region of the rotor, and a method of repairing an electrical generator by forming such a keyway. The present invention lengthens the operating life of the rotor by eliminating a stress-concentrating discontinuity and by reducing the loads in the highly stressed tooth region of the rotor.
(FR)L'invention concerne un générateur éléctrique pourvu d'une rainure, destinée à une clavette, formée uniquement dans la partie polaire du rotor et non dans la partie dent, et un procédé de réparation du générateur électrique, selon lequel on forme une telle rainure. La présente invention permet d'allonger la durée de vie du rotor par l'élimination d'une discontinuité de concentration des contraintes et par la réduction des charges dans la partie dent soumise à de fortes contraintes.
