The KOP-GRID® coupling, when under extreme loads, transmits the full load directly to driven equipment with the entire grid in full contact with the hub tapered teeth. The coupling is flexible within its rated capacity.
The grid design functions as a resilient coupling by damping torsional vibration and cushioning shock loads. This results in reduced vibration at the output end of the coupling. Peak loading is reduced, for smooth torque transmission, to help protect connected equipment from potentially damaging vibratory loads.
A second function of the grid design is that it can act much like a protective overload shear device. During an extreme overload, the grid can shear, reducing the possibility of damage to expensive machinery and equipment. The outer edges of the grid contact the hub tapered teeth for light loads. This leaves a long span to bear the load variations while still compensating for misalignment.
The grid is free to flex and dampen shock loads, even as the load increases. The span between the support ends shortens with increasing load. However, the grid is still free to flex, cushion shock and compensate for misalignment.
Movement of the grid in the hub grooves accommodates parallel misalignment while dampening shock and vibration. The grid/groove design permits a rocking and sliding action. This occurs without loss of power through the resilient grid. End float is permitted for both driving and driven shafts because the grid slides freely in the lubricated grooves.
