Maintaining Component Integrity in Wastewater Treatment Plants
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.

Eliminate Unnecessary Downtime in Asphalt Mixing 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.

Productivity Solutions for Food Processing
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 these connections are subjected to outside elements that can affect alignment. Climax Keyless Rigid Couplings are easy to install with simple hand tools, eliminating the need for brackets and expensive structure to support the motor, as well as installation misalignment. They contain no flexible elements saving maintenance costs and subsequent downtime. Torque mounting ensures that shafts are in perfect alignment, and C600s provide high torque (more…)
Keyless Locking Devices Eliminate the Need for Keyways in the Oil & Gas Industry
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 to prevent keyway failures. Climax Series C600 Keyless Rigid Couplings with a step-bore inner ring provides this solution. A Climax Keyless Rigid Coupling creates a high pressure high capacity mechanical interference fit that eliminates the “slop” from the connection while providing the reassurance that a keyway failure is avoided. Additionally, the zero backlash connection is unaffected by (more…)
Timing Solutions for Steel Mill Production Lines
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.
The hot rolled bar production line in a steel mill has gears in the transfer station for lifting the hot metal bars. These gear/lifting arm combinations demand strict sync tolerances in order for the transfer process to run smoothly. Eventually as these arms pick up and transfer large quantities of very long steel bars, the keyed connection is compromised, causing the lifting arms to lose synchronization and production to be halted. This need to periodically re-align the gears and/or replace expensive keyed shafting is often very expensive, difficult, and time consuming. (more…)
