Grid Coupling

Understanding Grid Couplings

Grid couplings consist of two hubs with external tapered teeth (grooves), a flexible spring steel grid element, and a two-piece cover (split horizontally or vertically) secured with gaskets and fasteners. Torque is transmitted through the grid element, which flexes and slides within the lubricated grooves to accommodate misalignment and absorb shock.

Key Advantages:

• High Torque Density: Capable of transmitting significant torque relative to their size.
• Excellent Vibration Damping: The flexible grid effectively absorbs torsional vibrations, protecting machinery.
• Shock Load Absorption: The grid can deform under sudden impacts, reducing peak loads on connected shafts and bearings.
• Accommodates Misalignment: Compensates for angular, parallel, and axial misalignment within specified limits.
• Torsional Flexibility: Provides flexibility under twisting loads, beneficial in systems with uneven torque.
• Replaceable Grid: The grid element is a wearable part that can be easily replaced without moving the hubs or connected machinery (using split covers), reducing downtime.
• Ease of Maintenance: Simple design; requires periodic re-lubrication with appropriate grease.

Common Configurations:

• Horizontal Split Cover: Allows grid replacement without disturbing connected equipment. Most common type.
• Vertical Split Cover: Suitable for higher operating speeds and applications where horizontal clearance is limited.
