Consisting of two radially slotted hubs and a serpentine spring metal band, the mesh coupling supplies the torsional damping and overall flexibility of an elastomer, but with the energy of steel. 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 typically tapered for better hub contact and less complicated assembly. Lubrication is needed thanks to the motion in between the speak to hub and the mesh steel areas.
