Abstract
A tension assembly for a jaw crusher includes a mechanical actuator and bias member. A robust and compact arrangement is provided by positioning the bias member, in the form of a coil spring, over the actuator rod and to configure the force transmission pathway through the linear actuator and into the coil spring so as to follow a reverse pathway through the assembly.
Claims13
A moveable jaw mounting assembly for a jaw crusher, the assembly comprising:
- a mechanical actuator to provide a pulling and/or a pushing force to a moveable jaw of the crusher, the actuator comprising a barrel having an internal chamber, a piston housed within the chamber and capable of reciprocating linear sliding movement within the chamber;
- a piston rod attached to the piston and capable of longitudinal reciprocating extension and retraction relative to the barrel, the rod having a first end positioned furthest from the barrel;
- a bias member to provide a return force to the moveable jaw;
- and
- a load bearing support frame to couple at least a part of the assembly to a part of the jaw crusher, wherein a region of the barrel is connected to the moveable jaw, the bias member including a first and a second end, the bias member being coupled to a region of the piston rod substantially at or towards the first end of the bias member, the support frame including a mount region to mount the bias member at or towards the second end, and wherein the mount region is positioned between a region of the barrel and the first end of the rod in the longitudinal axis direction such that the bias member extends over at least a region of the rod.
