Abstract

Petit moteur à turbine à gaz comportant un arbre de turbine 10 et un arbre d'entrée 14 de boîte de vitesses alignés coaxialement et montés dans trois roulements. L'arbre de turbine 10 est pourvu d'une surface conique mâle tandis que l'arbre d'entrée 14 de boîte de vitesses est creux et comporte une surface conique femelle 38 faite pour épouser la surface conique mâle 30 de l'arbre de turbine. L'arbre de turbine comporte aussi une saillie axiale filetée 34 logée dans la partie creuse de l'arbre d'entrée de boîte de vitesses. Un écrou 42 pourvu d'un épaulement 44 est vissé sur la saillie filetée de l'arbre de turbine 10 et vient en prise avec un épaulement 40 prévu à l'intérieur de l'arbre creux d'entrée de boîte de vitesses de façon qu'une torsion appliquée à l'écrou produise la mise en prise axiale des surfaces coniques. Une partie cannelée complémentaire 32, 33 peut être prévue d'une part entre la saillie et la surface conique mâle de l'arbre de turbine 10 et d'autre part entre l'épaulement d'appui de l'écrou 42 et la partie conique femelle de l'arbre d'entrée 14 de boîte de vitesses. L'accouplement entier se trouve à l'intérieur du diamètre des deux arbres coaxiaux.
