Abstract
An apparatus for a clarifier including a central pier terminating in a base plate having a circumferential edge and a ring gear rotatable about the central pier and coupled to a rake structure, the apparatus including a plurality of support bearings and a retaining ring structure. A lower surface of each support bearing seated on and supported by a portion of the base plate and a portion of an upper surface of each support bearing for support of a portion of the bottom of the ring gear, the support bearings placed substantially end-to-end to form a circular bearing extending towards the circumferential edge of the base plate. The retaining ring structure in rotative contact with a portion of the outer circumferential surface of the ring gear, the ring structure including a plurality of removably coupled semi-circular retaining members forming a circular hoop extending normal to the circumferential edge of the base plate, a portion of the circular hoop coupled to the circumferential edge of the base plate, wherein the retaining ring structure aligns the ring gear to rotation about a fixed axis. The apparatus may also include an adjustment mechanism selectively operable with the ring gear to adjust a vertical position of the ring gear relative to a top surface of the base plate.
