Two oil chamber counterweight

A cone crusher comprising:

• a stationary bowl;
• a head assembly positioned for gyrational movement within the stationary bowl to create a variable crushing gap with the stationary bowl, the head assembly including a crushing head;
• an eccentric assembly rotatable about a main shaft to impart gyrational movement to the head assembly within the bowl;
• a counterweight mounted to the eccentric assembly for rotation with the eccentric assembly, the counterweight including a vertical separating wall extending from a horizontal floor to define and separate an inner oil chamber and an outer oil chamber;
• and
• a splash shield having a radial outer end mounted to the vertical separating wall such that the splash shield overhangs at least a portion of the horizontal floor to further separate the inner oil chamber and the outer oil chamber.

A counterweight for use with a cone crusher, the counterweight comprising:

• a horizontal floor extending between an inner edge and an outer edge;
• a vertical separating wall extending horn the horizontal floor and positioned between the outer edge and the inner edge of the floor;
• a splash shield having a radial outer end mounted to the vertical separating wall and an inner end extending toward the inner edge of the floor to define an inner oil chamber;
• an inner wall extending from the floor and positioned radially outward from the vertical separating wall, wherein the inner wall, the splash shield and the vertical separating wall define an outer oil chamber;
• a plurality of spaced inner chamber drain holes extending through the floor and positioned within the inner oil chamber;
• and
• a plurality of spaced outer chamber drain holes extending through the floor and positioned in the outer oil chamber.
