Custom Designed Two-Piece Couplings Offer a Superior Solution for Line Shafts
Climax Two-Piece Clamping Couplings provide a superior solution for line shaft failed components, saving countless hours of downtime and increasing productivity.
Climax Custom Designed Coupling
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. As a result of using a one-piece tapered bushing, maintenance was tasked with the tedious process of removing all other components mounted between the bushing and the egress point. This removal process was often labor-intensive and required extended downtime, resulting in a loss of profits and productivity.
Climax’s knowledgeable engineering team, in collaboration with the customer, designed a two-piece clamping coupling with a welded lever arm as a solution to the customer’s problem. The two-piece clamping coupling was designed with sufficient torque and axial load capacity to address the failure issue faced by the customer. Additionally, the use of a (more…)
Superior Solution for Shaft Connections in Large Bore Applications
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.
Keyless Locking Devices Provide Solution for Steel Mill Gearbox Applications
Climax Keyless Locking Devices provide steel mills with a cost-effective and low-maintenance alternative to traditional gearbox mounting methods improving efficiency and reducing long-term maintenance costs.
Steel Production Facility
In the steel industry, gearboxes that drive mills are typically coupled to motors using large gear couplings. Traditionally, these couplings are mounted using a heavy interference fit, which requires expensive close-tolerance machining. The installation and removal processes necessitate heating the hub, as well as using a press or puller. This method not only demands significant time and effort but also poses risks to the equipment. Heated hubs can cause seal damage and lead to premature bearing failure. Likewise, when bearing maintenance is necessary, the removal and reinstallation of these couplings becomes labor-intensive and costly.
By incorporating a Climax Shrink Disc, steel mills can bypass these issues. Shrink discs offer a simple and superior alternative that eliminates the need for interference fits, heated hubs, and specialized tools. Climax Keyless Locking Devices and Shrink Discs, provide higher torque, bending and axial thrust capacities, ensuring a reliable performance. The elimination of axial movement during installation enhances precision and stability in the application. KLDs remove notch factors associated with keyways while reducing stress concentrations and potential failure points.
A Solution to Simplify Maintenance in Traditional Stamping Presses
Climax Keyless Locking Devices eliminate the use of keyed shafts required when mounting bull gears in mechanical steel stamping presses, providing a shaft-to-bore connection that is reliable, increased durability, and supplies infinite timing capability.
Bull gears are widely used in traditional stamping presses. After some time the bore of these bull gears will wear out and require maintenance. The typical maintenance approach is often lengthy and consequently affects production and profitability to the manufacturing facility. This process includes welding the bores to enable the plant to machine them back to the required shaft size and finally add a keyway.
In addition, the keyed shafting will oftentimes need to be repaired or replaced which can be difficult and time consuming. Climax provides an exceptional solution that eliminates the need for keyed shafts. Our keyless locking assemblies can be placed in the bore of the bull gear, to lock it to the shaft and provide the necessary torque capacity, while increasing durability, as well as supply infinite timing capability.

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…)
