Tests Reveal That All Grid Couplings Aren''t the Same
A grid coupling consists of two hubs, a grid element, cover and seals. The hubs transmit torque through teeth that engage the grid element, while the cover and seals protect the grid element and lubrication. The grid element is arguably the most critical part of the coupling as it absorbs misalignment and vibration, providing torsional softness.
