OLDHAM’S COPLING

16. History:-
The coupler is named for John Oldham who invented it
in Ireland, in 1820, to solve a paddle placement problem in a
steamship design.
Defining:-
An Oldham coupler is a method to transfer torque
between two parallel but not collinear shafts.
Derivatives:-
It has 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.

20. Advantages:-
 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.
 Protects support bearings by exerting consistently low
reactive forces, even under large misalignments.

21. Dis-advantages
 Slightly non-homokinetic transmission (that is, the driven
and driving shafts don't 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.

22. 22
Application
 It was basically invented to connect two parallel non co
axial shafts.
 It is not of much importance now as gears are being used.
