Disc screen construction

摘要

A die stamp formed disc construction including a toothed plate and a two-stepped sleeve integrally formed thereon. The sleeve has coined or stamped interior and exterior forty-five degree flats. The flats are accurately positioned so that, with the discs received through their central openings and clamped together onto the rotation shaft, the interior flat of one disc is held directly against the exterior flat of the adjacent disc thereby accurately and consistently positioning and holding the toothed plates of adjacent discs in spaced relation and preventing disc wobble.
