Actual Working Of Oldham's Coupling | Simple Explanation | Mechanism

Oldham’s coupling is a power transmission mechanism. In 1820 John Oldham invented it in Ireland. This mechanism is inversion of double slider crank chain mechanism. It is a type of flexible coupling which is used to connect two non-coaxial parallel shafts. Advantages- 1) The driving and driven shafts rotate at the same speed. 2) It has good torsional stiffness and zero backlash. 3) It exerts low reactive forces that protect the support of bearings. 4) It has low moment of inertia and has an easy installation in blind. 5) Replaceable wear elements are economical. 6) Accept large radial misalignment 7) Center plastic disc have the potential for electrical insulation. Disadvantages- 1) Accepts relatively smaller angular misalignment. 2) It possesses lower peak torque and torsion elasticity. 3) When the torque reaches the maximum value, axial reaction loads are applied to the support bearings. #Doubleslidercrankchainmechanism #Flexiblecoupling #Mechanism #Oldhamscoupling
