ABSTRACT:
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.
