Abstract
A sealing system for effecting a seal around a rotatable cylindrical shaft. The system is intended to be employed with a shaft which extends through a wall, such as a boat hull, into an aqueous environment. The system employs an elastomeric seal which defines an aperture therewithin, and the seal is intended to be fitted around the rotatable shaft which it is intended to seal. Structure is provided to mount the seal at a location generally coaxial with the shaft and spaced from the wall on a side thereof opposite that of the fluid environment. Axially-extending grooves formed in a wall defining a continuous passage provided in, for example, a bearing/housing assembly which mounts the seal, can be employed to conduct fluid from the fluid environment to the location of the seal to effect lubrication and maintenance of the seal in a compliant state,
