Grid couplings are a popular coupling option where both high torque levels and dampening requirements exist. Unlike gear and disc couplings, which are alternative metallic coupling types capable of transmitting a significant amount of torque, grid couplings have a unique ability to reduces vibration by as much as 30%. They also cushion shock loads to safeguard driving and driven power transmission equipment.
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.
