A grid coupling is comprised of two hubs, a grid spring element, and split cover kit (which includes two cover halves, gaskets, seals, and hardware).Grid couplings are available with either a horizontal or vertical split cover design.
Grid couplings are multi-piece mechanical shaft couplings used to transmit torque and rotation between shafts in mechanical power transmission assemblies. Their design allows them to accommodate the slight variations in alignment that occurs between connected shafts, while also absorbing shock loads.
The grid spring element absorbs impact energy by spreading it out over time, and thus reduces 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. As the load increases, more of the tooth comes into contact with the flexible grid spring element.
