Climax keyless locking devices provide advantages over keyed connections. Mining OEMs incorporate keyless connections in equipment design.
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.

Climax keyless locking devices offer an alternative for clumsy clevis pin retention and brake rotors in excavators and dragline shovels.
One of the most commonly used pieces of heavy mining equipment is excavators or power shovels. Every major construction project requires their use. Tasks such as removing large objects, digging trenches, site grading, hauling, demolition, mining, snow removal, would be practically impossible without this machinery.
Construction machinery is constantly subjected to the harshest environments and toughest loads for which an engineer can design. Maintenance is an important factor in keeping costs down and ensuring that construction site progress stays on schedule. Moving parts are expected to wear out over time especially where Continue reading “Mining Shovels & Excavators Benefit From the Use of Climax KLDs”
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 Continue reading “KLDs Offer Solution for Mining Crusher Equipment”
Climax Shrink Disc style flanged couplings in lieu of bore-keyway-setscrew or interference fits, allows for stronger shafts while eliminating corrosion sites and stress risers that are a common point of failure.
Mounting couplings with traditional keyed connections in treatment applications such as clarifier drives and drag conveyors, 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. Once assembled, keyways are at risk of corrosion build up resulting in backlash and fretting. In wastewater applications where slow rotation requires a greater torque, keyways produce a great risk for timing issues, resulting in downtime and loss of profit. Climax KLDs eliminate the need for keyways reducing the risk of corrosion, providing a longer life for clarifier drives and drag conveyors.
Using a press or shrink fit method, while effective Continue reading “Maintaining Component Integrity in Wastewater Treatment Plants”
Climax Keyless Locking Assemblies facilitate the repair and rebuild of rotary asphalt plant trunnions providing a cost-effective and maintenance-friendly alternative to the traditional sweat fit methods.
Asphalt plants incorporate the use of a series of trunnions for rotating drums containing hot asphalt mix. For years these trunnion wheels were manufactured from one piece of steel forged to the precise dimensions, or more commonly, an expensive and troublesome “sweat fit” assembly where the axle runs between two bearings and the mounted wheel. In the event of a bearing failure or tire replacement, an assembly repair is required. Most often disassembly of the axle from the wheel is extremely difficult and often impossible requiring the assistance of heat and high tonnage presses.
The loss of productivity during this often lengthy Continue reading “Eliminate Unnecessary Downtime in Asphalt Mixing Plants”
Climax C600 Series Keyless Rigid Couplings provide a superior cost-effective method to mount motors and gearboxes over traditional approaches in food processing applications.
Traditional methods to mount hydraulic motors and/or gearboxes require expensive motor mounts and rely on flexible couplings. Failure to properly align shafts in these applications can lead to premature coupling failure, and consequent downtime. Additionally, misalignment can lead to hydraulic motor leaks and bearing failures due to inordinate facial loads on the motor bearings.
Even when these components are properly aligned Continue reading “Productivity Solutions for Food Processing”
Climax Keyless Locking Devices used in place of keyways when mounting shaft components for manufacturing cold rolled steel and welded pipes eliminate fretting and associated equipment damage.
Traditionally, manufacturers of cold rolled steel and welded pipes in gas transmission use multiple hydraulic motors to drive the steel conveying rolls. These hydraulic motors are typically mounted onto a shaft with the use of keyways. The application subjects the motor/shafting to frequent and severe shock loading which causes a systemic problem of keyway failure. Due to reverse bending moment, the slip fit rigid flanged coupling with a standard keyway and two set screws often faces issues such as fretting, resulting in catastrophic failures. These failures cause the manufacturer unnecessary expenses in damaged equipment, including extensive labor and loss of production.
Climax Metal Products decided to look for alternate solutions Continue reading “Keyless Locking Devices Eliminate the Need for Keyways in the Oil & Gas Industry”
Climax Keyless Locking Assemblies provide timing solutions for steel mill production lines providing a cost-effective and maintenance-friendly alternative to traditional keyed connections.
Traditional methods used to mount mechanical power transmission components in steel mills, incorporate the use of gears and keyways. After some time these keyed connections begin to deteriorate causing components to become out of sync, resulting in maintenance issues and downtime consequently affecting the production and profitability of the mill.
