  • the second first transmission member 33 receives the counterclockwise rotational force of the second first rotor 11b, and the second (final end) second reverse member 45 is second (final end). The clockwise rotational force of the second rotor 21b is received.
  • the first inverting member 43 receives the rotational force of the first rotors 11a and 11b through engagement with the second driving member 35. In this way, the rotational force of the first rotors 11a and 11b and the rotational force of the second rotors 21a and 21b are both transmitted to the second inversion member 45 at the final stage, and the driven member engaged with the second inversion member 45. Output to the output shaft 55 via 53.
  • the second motor member 35 and the first inverting member 43 for rotation reversal are disposed at the input terminal, they may be disposed at the final stage as required by design, All may be arranged at the stage. When arranged at both the input end and the end, there is an advantage that the reverse load is distributed.
  • Reverse rotation device for a fluid machine can be utilized in a variety of fluid machines, such as gas turbines, steam turbines, jet engines, wind turbines.

Abstract

La présente invention concerne un dispositif contrarotatif pour machines à fluide, qui convertit de l'énergie issue du mouvement d'un fluide en énergie mécanique. Le dispositif contrarotatif pour machines à fluide comporte : au moins un premier rotor sur la périphérie intérieure duquel est formé un organe de contact intérieur, et une pluralité d'ailettes formées sur une périphérie extérieure de celui-ci et tournant dans un premier sens en fonction de l'écoulement de fluide ; au moins un deuxième rotor sur la périphérie intérieure duquel est formé un organe de contact intérieur, sur la périphérie extérieure duquel est installée une pluralité d'ailettes tournant dans un deuxième sens opposé au premier sens en fonction de l'écoulement de fluide, et qui est disposé de façon coaxiale et alternée avec le premier rotor ; une pluralité d'unités d'entraînement disposées radialement autour d'un axe du premier rotor afin de recevoir une rotation de l'organe de contact intérieur du premier rotor ; une pluralité d'unités d'inversion disposées radialement autour d'un axe du deuxième rotor et intercalées avec la pluralité d'unités d'entraînement, servant à inverser la rotation de la pluralité d'unités d'entraînement et à relayer la rotation à l'organe de contact intérieur du deuxième rotor ; et une unité de sortie servant à délivrer la force de rotation du premier rotor et du deuxième rotor.
