Abstract

An improved apparatus for crushing materials, such as coarse stone, includes a movable jaw which is reciprocated relative to a fixed jaw upon operation of a thrust transmitting drive assembly by a motor. The motor is connected with the drive assembly through a hydraulic torque transmitting and limiting assembly to prevent overloading of the crushing apparatus. The drive assembly includes a drive shaft having a circular thrust transmitting surface which is eccentrically offset and tilted relative to the central axis of the drive shaft. A second circular thrust transmitting surface is disposed on the movable jaw. A thrust transmitting sleeve is disposed between the two circular thrust transmitting surfaces and has circular surfaces which are disposed in continuous abutting engagement with the two thrust transmitting surfaces. Upon rotation of the drive shaft, the eccentric and angled thrust transmitting surface on the drive shaft causes the thrust transmitting sleeve to move as a conical pendulum to effect reciprocation of the movable jaw. The drive shaft is movable axially to compensate for wear of the jaws and to vary the size of an outlet opening through which the crushed material passes.
