Climax two-piece clamping couplings provide a superior solution for line shaft failed components, saving countless hours of downtime and increasing productivity.
Line shafts are an essential element in the power transmission industry and are used primarily to synchronize multiple components on equipment. Line shafts are common in many industries, including Timber, Forestry, Food Processing, Glass Production, Bottling, and Mills.
Recently, a customer was faced with a challenge where a one-piece tapered bushing used to mount several lever arms onto a line shaft continued to fail.
Climax large bore shaft couplings provide a higher strength alternative over antiquated traditional approaches in timbering applications while transmitting higher loads necessary for line shafts.
From initial harvesting to final product, machinery used in forestry (sawmill) applications is constantly subjected to some of the harshest environments and strenuous loads for which an engineer can design.
The true workhorse of the coupling family, rigid couplings can be used in many line shaft applications in the timber industry.
Traditional large cast iron couplings, used to connect shafts in large bore applications found in lumber, steel, rail, recycling, and paper industries, are manufactured from iron and are extremely heavy.
Large cast iron couplings have a bulky design that requires extra room in order to accommodate the oversized outside diameter of the unit. The sheer size of these antiquated couplings puts unnecessary stress on the shaft, and poses risk to damaging the shaft and associated components. In order to attain necessary torque for these applications, cast iron couplings encompass the use of a keyway leading to issues such as wallowing, backlash, fretting corrosion, and fatigue failure, commonly associated with keyways.
Climax Keyless Locking Devices withstand the constant pounding associated with timber processing applications making them an ideal replacement for expensive and time consuming traditional interference fit connections.
Sawmill Systems and Planer/Feed Tables commonly incorporate traditional keyed connections when attaching feed rollers in sawmill equipment. Using a keyed connection adds weight and cost not only to the shaft but to every component on the shaft. Over time, keyways cause fretting corrosion, allowing for backlash, and do not transmit bending moments or axial loads.
Climax Keyless Rigid Couplings provide a superior solution for shaft mounted hydraulic motors and gearboxes over traditional approaches in timber conveying applications.
Traditional methods used to shaft mount hydraulic motors and/or gearboxes in conveyor application such as wood chippers; include the need for brackets and expensive structures to support the motor. Failure to properly align shafts in these applications can lead to premature coupling failure. Additionally, misalignment can lead to hydraulic motor leaks and total bearing failures due to inordinate facial loads on the motor bearings, resulting in maintenance issues and downtime consequently affecting production and profitability. Even when these components are properly aligned these connections are subjected to outside elements that can affect alignment.
Climax Keyless Locking Devices withstand the constant pounding associated with wood processing applications making them an ideal replacement for expensive and time consuming traditional interference fit connections.
Interference fit rotor/shaft connections common in wood chippers require expensive machining, fixturing, and the use of heavy hydraulic presses. As these traditional fits require close tolerances there is a great deal of labor involved to facilitate assembly.
Climax heavy duty locking assemblies can achieve the same fit with a much simpler and less expensive machining. Keyless locking assemblies are installed and removed with simple hand tools making them ideal for applications that require field serviceability. The same heavy duty locking assemblies can be used to mount drive sheaves on wood chippers eliminating wallowing, fretting corrosion, and fatigue failure, commonly associated with shaft keyways. The harsh demands of constant pounding in wood processing applications Continue reading “Keyless Locking Devices Provide Superior Connection Solution for Wood Chippers”
Climax Keyless Locking Devices provide a superior alternative for component connectivity in timber applications where keyed connections commonly result in excessive downtime and loss of production.
Due to the harsh nature of the lumber and wood industry, sheared and rolled keys and broken shafts are common on equipment such as debarkers. Shaft/hub connections in this industry are subjected to a constant pounding which eventually leads to shaft fatigue failures of keyed connections resulting in downtime and loss of production.
Climax Keyless Locking Devices provide timing solutions for lumber handling systems providing a cost-effective maintenance-friendly alternative to traditional keyed connections.
Lumber handling systems have gears in the transfer station used for lifting raw material. In order for these transfer stations to run smoothly they demand strict sync tolerances. Traditional keyed connections used in lumber handling systems can become compromised causing a loss of synchronization resulting in stopped production. This need to periodically realign the gears and/or replace expensive keyed shafting is often expensive, difficult, and time consuming.
Climax Series C133 Locking Assemblies negate the need for keyways in drive sprocket applications often allowing for the use of A-Plates. When used with kicker arms our keyless locking devices do not require gang broaching or the need to locate keyways on shafting, resulting in reduced machining costs. Under the extreme operating environments of lumber handling systems, KLDs eliminate the need for keyed connections and the associated problems with backlash and fretting corrosion which over time can cause weakened shafts and/or shaft failures.

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.
