ABSTRACT:
A wheelmotor direct-drives the bucketwheel for wet underwater service in dredging. This eliminates the combination of an intervening gear box and a watertight chamber to house the rotating shaft hydraulic motor of conventional dry underwater service practice. In a preferred embodiment, a compression seal is provided which is adapted to create a chamber within the seal thereby providing a first line of defense against the intrusion of water into the junction of the stationary shaft and the rotating case. By injecting underwater lubricating grease into this chamber, displacing all of the air therein, the sliding contact surfaces are lubricated and a second line of defense against the intrusion of water is provided.
