Gyratory crusher main shaft mounting assembly

摘要

A gyratory crusher eccentric support assembly to support the gyroscopic precession of a main shaft (107) extending through the crusher. The eccentric assembly comprises an inner bushing (126) retained in position by a surrounding sleeve (125) with the sleeve supported at its axially uppermost region by an annular support ring (122). A locking flange (209) prevents axial displacement of the bushing that is configured specifically to facilitate the removal and replacement of the bushing wear part.
