    Patent number: 6604699
    Abstract: The head nut assembly for gyratory crusher which includes a shaft having a lower portion, a tapered middle portion and a threaded upper portion. The threaded upper portion extends above the tapered portion. A mantle encompasses the middle tapered portion and has a correspondingly tapered internal side. The internal side is in generally continuous supportive engagement with the shaft middle portion. The mantle additionally has an upper side. A head nut is threadably secured to the upper portion of the shaft. The head nut has a lower face, where at least one bore extends upwardly into the lower face. An annular ring is disposed around the shaft between the mantle and the head nut. The ring has a lower surface coupled with the upper side of the mantle so as to prevent relative rotational movement between the mantle and the ring. An upper surface on the ring is contiguous with the lower face of the head nut. At least one key is disposed between the head nut and the annular ring.
