The Lovejoy G-Type Flexible Grid Coupling reduces vibration by as much as 30%, and cushions shock loads to safeguard your driving and driven equipment. The flexible nature of the spring-like grid absorbs impact energy by spreading it out over time, thus reducing the magnitude of the peak loads. This is possible because of the progressive contact that occurs
between the curved profile of the hub teeth and the flexible grid. Therefore, as the load increases, more of the tooth comes into contact with the grid, thus supplying superior protection and supreme performance.

Lovejoy G-Type Flexible Grid Couplings are designed for versatility. Common hubs and grids are used within a given size range for both horizontal and vertical split cover models. Grid installation and replacement is a “snap” at only a fraction of the complete coupling cost.

Benefits of the Grid Coupling include:
- Our G2000 Series Tapered Grid coupling is fully interchangeable with industry standards
- Quick installation and easy maintenance reduces labor and downtime costs
- Torsionally flexible and resilient - reduces vibration, plus cushions shock and impact loads
- Versatile stock components can be used with either horizontal or vertical covers. Cover fasteners available in either Metric or Imperial sizes
- High tensile, shot-peened alloy steel grids and precision machined hubs ensure superior performance and long life

Top Quality Manufacturing
|
|
Made from a high tensile alloy steel, the grid spring is carefully formed to shape, then hardened and tempered under controlled conditions. Next, the grids are shot-peened, compressing the surface molecules and leaving a residually stressed surface. This process creates a stronger surface in compression.
|
|
|
|
Any load applied on the coupling in operation must first surmount the compressive forces created by peening before the tensile stress reaches the grid. This provides a dramatic increase in rating over other coupling types, increases reserve strength for longer life and may permit selection of a smaller coupling, thus reducing cost.

The Lovejoy Grid spring/hub tooth arrangement has been specifically designed for optimum performance and supreme reliability. Not only does the hub tooth profile permit progressive loading under torsional shock conditions, but unique root radii are incorporated to significantly improve the fatigue life of the teeth.
