Grid Couplings
GRID COUPLINGS can carry considerable torques despite their compact sizes. This type of all-metal flexible coupling is mainly used to reduce the transmission of vibration and shock loading, while allowing both angular and parallel misalignments within their operational limits.
When a heavy overload happens, or an excessive misalignment occurs, the grid and its cover fail, acting as a safety device. This way, the transmission of torque is interrupted, and other costlier components of the drive are protected against damage.
Compared to others, this type of coupling has a simpler installation and repair. Besides, grid couplings have higher reliability. Therefore, they require less and shorter maintenance inspections.

Condition of grid under light load
Each grid segment works as a long straight beam supported by the root side surfaces of the hub teeth. Coupling torsional rigidity is low, so light loads twist it gently.

Condition of grid under normal load
Each grid segment works as a slightly flexed beam supported by the lower half side surfaces of the hub teeth. Coupling torsional rigidity is high, so normal loads twist it gently.

Condition of grid under shock or start load
Each grid segment works as a very short flexed beam supported by the full side surfaces of the hub teeth. Coupling torsional rigidity is very high, so peak loads twist it gently.
