drive for the waves of clean, krähl or mixers

摘要

The drive for raking, thickening and rabbling mechanisms circulating in round clearing basins contains at least one ball-bearing slewing rim which consists of an inner raceway and an outer raceway which is driven via a gear rim with external toothing. The frame, in which the ball-bearing slewing rim and its drive are mounted, is now enlarged inwardly in a tank shape and consequently forms an annular tank, in which permanent lubricant is accommodated. The flange, which is connected to the outer raceway and which makes the connection to the central shaft of the raking or rabbling mechanism, is according to the invention drawn over the inner wall of the annular tank in an offset manner. This new construction makes possible exchange of the ball-bearing slewing rim and of the drive without dismantling the annular tank and the raking or rabbling mechanism. IMAGE
