DESCRIPTION

Couplings are devices which are mainly used to transmit rotational energy (namely rotational torque, rotational movements) from a shaft to another shaft. Couplings are divided to rigid and flexible types. In rigid couplings, oscillation is insignificant in the transmitted torque (such as shell couplings). Wearing doesn’t occur in this kind of coupling; it doesn’t need maintenance and can be used in both rotation directions. This type of coupling provides shaft to shaft connection or shaft to flange connection through friction of conical surface on each other. Strong bolts assemble conical surfaces on each other
