  • Clarifier drive for waste water treatment system
    Patent number: 5264126
    Abstract: An improvement is provided in a water or wastewater clarifier drive mechanism to permit access to or removal of the hoop gear assembly without draining the clarifier or disconnecting the drive cage from the pier that supports it. A torque transfer ring is provided to couple the drive cage support to the hoop gear. A plurality of support screws are employed to temporarily support the drive cage support on the drive housing during maintenance operations. With the drive cage support supported on the drive housing, the torque transfer ring may be removed, thereby providing unobstructed access to the hoop gear and bearings for maintenance or replacement. A maintenance platform is also described that is adapted to be temporarily supported by the drive cage support and to provide clearance for removal of the torque transfer ring and the hoop gear or bearing assembly.
