ABSTRACT:
Sealing system for a housing containing gears operated in a lubricated environment, the housing having an opening through which a shaft supported in a bearing assembly extends for mating with at least one of the gears in the housing. Sealing system includes a seal arranged in the opening through which the shaft extends, the seal being located between the bearing assembly and the interior of the housing whereby the seal will be exposed to lubricant from the interior of the housing, but such lubricant will be prevented from leaking from the housing at the shaft input opening. Sealing system may also include a grease filled chamber between the seal and the bearing, and a packing gland located adjacent the bearing on the side of the bearing opposite the seal.
