  • Gearbox assembly for gyratory and cone crushers
    Patent number: 8328125
    Abstract: A gearbox assembly for a gyratory crusher and/or cone crusher, which includes a drive shaft having a rotational movement, and a drive shaft gear attached to a distal end of the drive shaft. The drive shaft gear imparts a rotational movement of the drive shaft to a first gearing assembly, the first gearing assembly imparting a second rotational movement to a second gearing assembly, the second gearing assembly imparting a third rotational movement of the second gearing assembly to drive a ring gear, and wherein the ring gear is attached to and rotates an eccentric assembly of the gyratory crusher and/or cone crusher. The cone crusher is preferably configured to crush rock, stone, ore or minerals. A method of making or retrofitting a crushing device such as, for example, a cone crusher or other gyratory crusher, is also provided.
