Keyless Locking Devices Provide Solution for Steel Mill Gearbox Applications

Climax Keyless Locking Devices provide steel mills a cost-effective and maintenance-friendly alternative to traditional mounting methods for gearbox applications.

Gearboxes that drive mills in the steel industry are typically coupled to motors using large gear couplings. The traditional mounting method for these couplings is a heavy interference fit which require expensive close tolerance machining, a heated hub for installation and removal, and use of a press or puller. As a result, heated hubs can lead to seal damage and premature bearing failure. When bearing maintenance is required, removal and re-installation of these couplings is labor intensive and expensive.

Using a Climax Shrink Disc to mount gear couplings provides a superior alternative to a traditional press fit method. Keyless locking devices achieve the same fit with much simpler and less expensive machining. Climax KLDs provide high torque, bending, and axial thrust capacities, eliminate axial movement during installation, and eliminate notch factors associated with keyways. In addition, shrink discs are less expensive and time consuming than sweat or press fit connections. Installation and removal of KLDs require the use of simple hand tools allowing for easy field serviceability.
