Abstract
A drive mechanism for an inertia cone crusher having a drive transmission to rotate an unbalanced mass body within the crusher and to cause a crusher head to rotate about a gyration axis at a tilt angle formed by an axis of the crusher head relative to the gyration axis. A torque reaction coupling is positioned in the drive transmission between the mass body and a drive input component and is elastically displaceable and/or deformable. In particular, the torque reaction coupling is configured to: i) transmit a torque from the drive input to the mass body and ii) to dynamically displace and/or deform elastically in response to a change in the torque resultant from a change in the tilt angle of the crusher head so as to dissipate the change in the torque to the drive transmission.
