Locking Assembly Coupling: The Robust, Keyless Solution for Secure Power Transmission

In the world of mechanical power transmission, achieving a rigid, reliable, and maintenance-free connection between components is paramount. Traditional keyed connections often introduce stress points and require precise machining. A modern and superior alternative is the locking assembly coupling. This innovative device utilizes a friction-based locking mechanism to create a secure, concentric connection without keys. The CSF-A18 Type Locking Assembly Coupling from Apex Coupling exemplifies this technology, offering a robust and flexible solution designed to replace traditional couplings and serve as a high-performance alternative to brands like Lovejoy.

Advanced Locking Mechanism for Maximum Reliability

The core of this locking assembly coupling is its sophisticated “Double cone type + Mechanical type (wedge type)” tightening method. This dual-mechanism design works in unison to generate immense, uniformly distributed radial pressure when the locking screws are tightened. This powerful clamping force ensures a true keyless connection that is both incredibly rigid and free of backlash, guaranteeing perfect torque transmission and alignment between connected shafts and hubs.

Constructed with a body made of high-strength S45C steel and equipped with Grade 12.9 locking screws, this coupling is built for durability and can handle significant loads. Its design provides flexibility to accommodate minor misalignments while maintaining a solid torsional connection. With an allowable torque range from 1110 to 6400 N.m, it covers a wide spectrum of industrial applications, from medium-duty machinery to more demanding drives.

Technical Specifications and Customization

This versatile locking assembly coupling is designed for broad compatibility and ease of integration.

• Size Range: Available for inner hole diameters from 25mm to 320mm, with corresponding outer diameters from 50mm to 405mm, making it suitable for a wide variety of shaft sizes.

• Robust Construction: The straight-type (A18S) design and steel construction ensure long service life. Standard surface treatment is grinding, with options for bluing or nickel plating to enhance corrosion resistance for specific environments.

• Wide Applicability: This coupling is suitable for numerous industries, including Manufacturing Plants, Food & Beverage, Printing, Construction, and Energy & Mining. It is an ideal compact keyless connecting device for pumps, fans, compressors, and conveyors.

Simplifying Design and Enhancing Performance

By eliminating the need for keyways, this locking assembly simplifies the design and machining of both hubs and shafts, reducing costs and potential failure points. It allows for easy installation, repositioning, and disassembly, streamlining maintenance and component changes.
