ABSTRACT OF THE DISCLOSURE Cone crushers of the gyratory type, which incorporate an eccentric, rotatable about a stationary shaft, and which coacts with the depending skirt, of the movable crushing tool support cone, to impart a gyratory motion to the movable crushing tool. The invention contem- plates: providing a combination of both plain and roller hearings to mount the eccentric in the crusher, and for coaction with the lower crushing tool mounting cone; pro- viding the main thrust bearing assembly, which also serves to support the lower crusher tool mounting cone, with coacting surfaces that facilitate proper and complete lubrication of the hearing; providing a direct and efficient path of lubricant flow to the main thrust bearing assembly for all positions of adjustment of the crusher gap; pro- viding lubrication channels and flow patterns that insure proper lubrication of the plain hearing, and for that matter lubrication to all bearings that reach the bearing after being filtered and cooled and without first passing through other bearings; providing a counterweighted flywheel that is fabricated to not only offset the rotational effect of the eccentric but also with its rotational forces located and distributed to minimize unwanted moments about the center of gravity of the crusher.
