Traditional large cast iron couplings, commonly utilized to connect shafts in various heavy-duty applications such as lumber, steel, rail, recycling, and paper industries, are typically manufactured from iron and are known for their substantial weight.
Conventional large cast iron couplings feature a bulky design, necessitating extra space to accommodate their oversized outer diameter. The sheer size of these antiquated couplings places undue stress on the shaft and increases the risk of damaging both the shaft and its associated components. Likewise, to achieve the necessary torque for these applications, cast iron couplings rely on a keyway, leading to issues such as wallowing, backlash, fretting corrosion, and fatigue failure, all commonly associated with keyways.
Climax offers two solutions tailored for large bore applications. The first option, the H2CC-Series Large Bore Two-Piece Clamping Couplings, available with internal diameters up to 4 15/16”. This all-steel, rigid, two-piece clamping design not only reduces weight on the shaft but also addresses clearance issues with its tighter envelope. Additionally, it delivers a higher torque capacity compared to die cast couplings. Utilizing a clamping design, this steel coupling effectively transmits torque via keyways. The H2CC-Series Rigid Coupling weighs approximately half as much as their die cast counterparts and can be installed with minimal disassembly.
The Climax C600-Series Keyless Rigid Coupling represents an innovative solution that significantly reduces coupling weight while eliminating the risks associated with keyed connections. Integrating the C600-Series into application designs not only reduces maintenance costs but also minimizes downtime. Installation is simplified with basic hand tools, and the product can be mounted on a round shaft with or without a keyway. Lighter than both traditional die cast couplings and H2CC-Series Rigid Couplings, C600s offer a torque capacity 2-3 times higher and feature self-releasing capabilities.
