In an engine-generator set (10), the generator (13) has a first shaft (25) driving a generator armature (27) and also has a second shaft (19) in spaced relationship to the first shaft (25). The second shaft (19) is coupled to the engine (11) and there is a respective gear (21 or 23) on each of the shafts (19 25) which provides a "step-down" gear reduction for powering the generator (13) at, e.g., 1800 rpm, where the engine speed is greater than 1800 rpm. Preferably, the engine (11) is coupled to the generator armature shaft (25) through a torsional coupling (17) for isolating engine vibration from the generator (13).
Dans ce groupe moteur-génératrice (10), la génératrice (13) possède un premier arbre (25) entraînant l'induit (27) ainsi qu'un second arbre (19) tributaire du premier (25). Le second arbre (19) est couplé au moteur (11) et chacun des arbres (19, 25) est pourvu d'un pignon (21 et 23, respectivement) assurant une démultiplication "par paliers" dans le but de faire tourner la génératrice (13) à 1800 tours/minute par exemple, le régime du moteur étant, quant à lui, supérieur à 1800 tr/min. Le moteur (11) est couplé, de préférence, à l'arbre de l'induit de la génératrice (25) par un accouplement torsionnel (17) destiné à l'isoler des vibrations produites par la génératrice (13).
