Description

A jaw coupling is a type of power transmission coupling for general purposes that can also be used in applications of motion control (servo). It is designed to transmit torque (by connecting two shafts) while damping device vibrations and accommodating misalignment, which protects other components from damage. Jaw couplings consist of three components: two metallic hubs and an element called an elastomer insert, but widely referred to as a “spider.” Jaw coupling torque is transmitted through the elastomer lobes in compression.
