For an Oldham coupling used between two shafts, which among the follow...
Oldham’s coupling is used to transmit power between two shafts having small angular misalignment. There is no bending load or reduction/increase of speed criterion.
Hence only I and IV statements are correct.
Hence only I and IV statements are correct.

For an Oldham coupling used between two shafts, which among the follow...
Oldham Coupling
- The Oldham coupling is a type of flexible coupling that is used to connect two shafts together. It is commonly used in mechanical systems to transmit torque and motion between shafts that are not aligned.
Correct Statements
I. Torsional load is transferred along shaft axis.
- This statement is correct. The Oldham coupling is designed to transmit torsional load along the shaft axis. It consists of three discs - two outer discs and one central disc. The central disc is connected to the two outer discs by means of pins. When one shaft rotates, it causes the central disc to rotate, which in turn transfers the load to the other shaft along the axis.
II. A velocity ratio of 1:2 between shafts is obtained without using gears
- This statement is correct. The Oldham coupling allows for a velocity ratio of 1:2 between the two shafts without the need for gears. This is achieved by the design of the coupling, which allows for a certain amount of angular misalignment between the shafts. As one shaft rotates, it causes the central disc to rotate, which in turn causes the other shaft to rotate at a different velocity.
Incorrect Statements
III. Bending load is transferred transverse to shaft axis.
- This statement is incorrect. The Oldham coupling is not designed to transfer bending load transverse to the shaft axis. Its primary function is to transfer torsional load along the shaft axis. If there is a significant amount of bending load, it can result in misalignment and excessive wear on the coupling.
IV. Rotation is transferred along shaft axis.
- This statement is incorrect. The Oldham coupling transfers rotation between two shafts, but it does not transfer the rotation along the shaft axis. Instead, it transfers the rotation through the central disc and the pins, which allow for a certain amount of angular misalignment between the shafts. The rotation is then transferred to the other shaft at a different angle.
Conclusion
The correct statements regarding the Oldham coupling are:
- Torsional load is transferred along the shaft axis.
- A velocity ratio of 1:2 between shafts is obtained without using gears.
- The Oldham coupling is a type of flexible coupling that is used to connect two shafts together. It is commonly used in mechanical systems to transmit torque and motion between shafts that are not aligned.
