The Grid Flex Couplings LGF Series are high-performance flexible couplings designed for efficient torque transmission with superior shock absorption and vibration damping. These couplings utilize a spring steel grid element that connects two slotted hubs, providing flexibility and resilience under dynamic load conditions.
Engineered for durability and reliability, Grid Flex Couplings are ideal for medium to heavy-duty industrial applications, especially where shock loads, variable torque, and misalignment are present. They offer a perfect balance between strength, flexibility, and ease of maintenance.
The spring steel grid absorbs and dissipates impact energy, making it ideal for applications with sudden load changes.
Reduces torsional vibrations, ensuring smooth operation and protecting connected equipment.
Capable of transmitting moderate to high torque loads efficiently.
Accommodates angular, parallel, and axial misalignment, reducing stress on shafts and bearings.
The flexible grid can be easily replaced without disturbing hubs, minimizing downtime.
Spring steel grid ensures durability and resistance to fatigue under cyclic loading.
Simple construction with accessible components allows quick inspection and servicing.
Components:
Two Metallic Hubs (Slotted Type):
• Manufactured from high-quality steel or cast iron
Spring Steel Grid Element:
• Precision-formed grid that fits into the hub slots
Cover Assembly with Seals:
• Protects the grid and retains lubrication
Lubrication System:
• Grease lubrication ensures smooth operation and reduces wear
Working Principle:
Torque is transmitted through the spring steel grid seated in the slots of both hubs. The grid flexes under load, absorbing shock and accommodating misalignment. The resilient nature of the grid helps distribute load evenly, ensuring smooth and efficient power transmission.
