Oldham’s couplings are widely used in many applications where power transmission is required even when the driver
and driven shafts are in non collinear axis. The slider part is made of plastics or reinforced resins or aluminium bronze, they
have good sliding effects but in the meantime they undergo plastic deformation during the application of transmission torque.
When the applied load becomes against the design load (shock/impact), the slider part eventually ruptures in the direction of
deformation. This causes to replacement of the slider material and in some cases, the entire assembly have to be replaced. This
involves in additional cost to the unit. In this project, to reduce the failures in Oldhams coupling and to make sure the
availability of the spares of particular part, we have concentrated on the design and optimization of parts of Oldham’s coupling
considering the 3D printing process.
