Consisting of two radially slotted hubs and a serpentine spring steel band, the mesh coupling provides the torsional damping and versatility of an elastomer, but with the power of metal. Grid couplings transmit torque and alter for angular, parallel and axial misalignment from one hub to the other by oscillating and sliding tapered grids in the hub grooves. The mesh cross section is generally tapered for much better hub get in touch with and simpler assembly. Lubrication is required thanks to the motion between the speak to hub and the mesh steel areas.
