This invention is directed to a seal device for an energy conversion device which has a rotating shaft supported by bearing assemblies containing lubrication. The seal device inhibits migration of the lubrication from a first portion of the shaft near the bearing assembly to a second portion of the shaft near electronic circuitry. The seal device includes a seal mounting structure which separates the first portion of the shaft from the second portion of the shaft. The seal mounting structure has a shaft receiving surface through which the shaft is placed. A groove is located in the shaft receiving surface and a seal is secured in the groove by various means and remains stationary with respect to the rotating shaft. The seal has an inner segment that surrounds the periphery of the shaft.
L'invention concerne un dispositif d'étanchéité pour un dispositif de conversion d'énergie qui présente un arbre rotatif supporté par des ensembles paliers contenant un agent de lubrification. Le dispositif d'étanchéité inhibe la migration de l'agent de lubrification depuis une première partie de l'arbre à proximité de l'ensemble palier vers une seconde partie de l'arbre proche des circuits électroniques. Le dispositif d'étanchéité comporte une structure de montage de joint d'étanchéité qui sépare la première partie de l'arbre de la seconde. Cette structure présente une surface de réception de l'arbre dans laquelle l'arbre est placé. Une rainure est située dans ladite surface de réception de l'arbre, rainure dans laquelle un joint d'étanchéité est fixé par divers moyens et reste stationnaire par rapport à l'arbre rotatif. Ledit joint comporte un segment interne qui entoure la périphérie de l'arbre.
