KLDs Offer Solution for Mining Crusher Equipment

Crushing machinery used in mining applications can benefit from the use of a Climax keyless locking device which provides advantages over keyed connections.

Jaw crushers used heavily in the mining industry, often incorporate keyways and/or expensive sweat or press fit connections. Using traditional keyed connections introduces several compromises. Whenever a shaft is keyed, it must be oversized to account for the loss of effective cross section. This adds weight and cost not only to the shaft, but to every component on the shaft. Keyways cause fretting corrosion, allow backlash, do not transmit bending moments or axial loads.

Impact crushers incorporate an interference fit rotor/shaft connection which requires expensive machining, fixturing, heavy hydraulic presses and a great deal of labor to facilitate assembly. Climax heavy duty locking assemblies such as the C405-Series achieve the same fit with much simpler and less expensive machining. Heavy duty locking assemblies can also be used to mount drive sheaves on these machines eliminating the disadvantages of keyways and belt alignment issues of QD XT bushings.

Mining machinery is constantly subjected to some of the harshest environments and torturous loads for which an engineer can design. Climax KLDs provide high torque, bending, and axial thrust capacities, eliminate axial movement during installation, eliminate notch factors associated with keyways, are less expensive and time consuming than sweat or press fit connections. KLDs are installed and removed using simple hand tools allowing for easy field serviceability.

Climax offers an extensive line of keyless locking devices from stock and has the ability to engineer custom designs.
