Climax Keyless Locking Devices eliminate the use of keyed shafts required when mounting bull gears in mechanical steel stamping presses, providing a shaft-to-bore connection that is reliable, increased durability, and supplies infinite timing capability.
Bull gears are widely used in traditional stamping presses. After some time the bore of these bull gears will wear out and require maintenance. The typical maintenance approach is often lengthy and consequently affects production and profitability to the manufacturing facility. This process includes welding the bores to enable the plant to machine them back to the required shaft size and finally add a keyway. In addition, the keyed shafting will oftentimes need to be repaired or replaced which can be difficult and time consuming. Climax provides an exceptional solution that eliminates the need for keyed shafts. Our keyless locking assemblies can be placed in the bore of the bull gear, to lock it to the shaft and provide the necessary torque capacity, while increasing durability, as well as supply infinite timing capability. This keyless solution simplifies the machining required, allows for timing, and provides for infinite service life. When maintenance is required, KLDs are installed and removed using simple hand tools. Climax carries an extensive line of shaft locking solutions from stock. Our engineers have the ability to engineer custom designs to fit any application challenge you may have.
From initial harvesting to final product, machinery used in forestry application is constantly subjected to some of the harshest environments and strenuous loads for which an engineer can design. To compensate, many application designers forgo traditional keys and keyways which are subject to failure and rely upon spline interference fits to mount critical components on rotating shafts.
Whether your operation is surface, conventional or longwall mining, your machinery is constantly subjected to some of the harshest environments and torturous loads for which an engineer can design. To compensate, for many application designers forgo traditional keys and keyways which are subject to failure and rely upon splice and interference fits to mount critical components on rotating shafts.
Drum pulleys, especially head or tail pulleys, using traditional keyed connections introduce 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. Once assembled, keyways are susceptible to fretting, corrosion, and allow backlash. QD, XT, or taper-lock bushings do not transmit reversing bending moments and are susceptible to shaft fatigue failure originating at the keyways. Climax KLDs eliminate the need for keyways reducing downtime and loss of profit while allowing the use of smaller shafting and components. KLDs provide a longer life for both mine duty and engineered class conveyor pulleys.
