摘要

A gyratory crusher eccentric support assembly to support the gyroscopic precession of a main shaft extending through the crusher. The eccentric assembly comprises an inner bushing retained in position by a surrounding sleeve with the sleeve supported at its axially uppermost region by an annular support ring. A locking flange prevents axial displacement of the bushing that is configured specifically to facilitate the removal and replacement of the bushing wear part.
