  • Seal arrangement for an electric motor
    Patent number: 6177744
    Abstract: A technique is provided for sealing a bearing cavity in a rotating machine such as an electric motor. The bearing cavity is defined by annular elements on either side of an antifriction bearing set. Seals are provided on the sides of the bearing cavity and are secured to a support structure, such as the motor housing, and include elements which ride against the rotating shaft during operation. The seals exert a sealing force against the rotating element which results at least partially from internal pressure within the bearing cavity provided by a pressurized lubricant stream. The lubricant stream is provided in the form of an airborne oil mist.
    Type: Grant
