It is a type of coupling designed to
transmit torque while damping system vibrations, which protects
other components from damage. Spider couplings are composed of
three parts: two metallic hubs and an elastomer insert called spider. The three
parts press fit together with a jaw from each hub fitted
alternately with the lobes of the spider. The curved jaws of the
hubs reduce deformation of the spider to maintain the zero-Standard:
