  • 3. OLDHAM’s COUPLINGHistory Thecoupler is named for John Oldham who invented it in Ireland, in 1820, to solve a paddle placement problem in a steamship design. A Presentation by : Akash Sood
  • 4. OLDHAM’s COUPLINGDefining An Oldham coupler is a method to transfer torque between two parallel but not collinear shafts. A Presentation by : Akash Sood
  • 5. OLDHAM’s COUPLINGDerivatives Ithas three discs, one coupled to the input, one coupled to the output, and a middle disc that is joined to the first two by tongue and groove. A Presentation by : Akash Sood
  • 6. OLDHAM’s COUPLINGPlacing Thetongue and groove on one side is perpendicular to the tongue and groove on the other. A Presentation by : Akash Sood
  • 7. OLDHAM’s COUPLINGExternal Mounts Often springs are used to reduce backlash of the mechanism. A Presentation by : Akash Sood

  • 10. OLDHAM’s COUPLINGAdvantages Protects driven component by serving as a mechanical "fuse" - an inexpensive replaceable plastic midsection shears under excess load. Protects support bearings by exerting consistently low reactive forces, even under large misalignments. Electrical insulation Accommodates large radial misalignment in a short length Accommodates much larger angular misalignment then standard Oldham coupling Easy installation in blind or difficult installations when through-bores are used Economically priced compared to other couplings with similar performance characteristics Inexpensive replaceable wear element Low moment of inertia A Presentation by : Akash Sood
  • 11. OLDHAM’s COUPLINGDis-advantages Lower peak torque and torsional stiffness than standard Oldham coupling Slightly non-homokinetic transmission (that is, the driven and driving shafts dont move at exactly the same speed throughout one rotation) when angular misalignment is significant Axial reactive loads exerted on support bearings when torque approaches maximum Accommodates only a small axial misalignment A Presentation by : Akash Sood
  • 12. OLDHAM’s COUPLINGApplication Itwas basically invented to connect two parallel non co axial shafts. It is a really good mechanism and transmits the same speed and same direction of rotation. It is not of much importance now as gears are being used. A Presentation by : Akash Sood
