Title (EN) SUPERCHARGER HAVING ROTOR WITH PRESS-FIT STUB SHAFTS
(FR) COMPRESSEUR DE SURALIMENTATION DOTÉ D'UN ROTOR À ARBRES TRONQUÉS À AJUSTEMENT FORCÉ
Abstract:
(EN) A supercharger constructed in accordance to one example of the present disclosure includes a housing, a first rotor, a second rotor and a rotor shaft assembly. The first and second rotors are received in cylindrical overlapping chambers of the housing. The first rotor has a central longitudinal passage. The rotor shaft assembly rotatably supports the first rotor and includes a first rotor shaft and a separate and distinct second rotor shaft. The first and second rotor shafts are press-fit into the central passage defined in the first rotor.
(FR) Un compresseur de suralimentation construit conformément à un exemple de la présente invention comprend un boîtier, un premier rotor, un second rotor et un ensemble arbre de rotor. Les premier et second rotors sont reçus dans des chambres de chevauchement cylindriques du boîtier. Le premier rotor a un passage longitudinal central. L'ensemble arbre de rotor supporte en rotation le premier rotor et comprend un premier arbre de rotor et un second arbre de rotor séparé et distinct. Les premier et second arbres de rotor sont ajustés à force dans le passage central défini dans le premier rotor.
