Oldham's Coupling - Explanation
Oldham's coupling is a type of coupling that is used to connect two parallel shafts. This coupling was invented by John Oldham in 1824. The Oldham's coupling is also known as the Oldham's coupling mechanism.
Oldham's Coupling - Inversion
The Oldham's coupling is the third inversion of the double slider crank chain. The double slider crank chain is a mechanism that is used to convert rotary motion into reciprocating motion.
Inversion is the process of changing the order of links and joints in a mechanism. The double slider crank chain has four inversions, and the Oldham's coupling is the third inversion of this chain.
Oldham's Coupling - Working
The Oldham's coupling consists of three parts - two discs and a central block. The two discs are mounted on the two parallel shafts, and the central block is mounted on a third shaft that is perpendicular to the other two shafts.
The central block has slots that are perpendicular to each other, and the two discs have pins that fit into the slots. When the two parallel shafts rotate, the pins slide back and forth in the slots, causing the central block to rotate.
The Oldham's coupling is used to connect two parallel shafts that are not perfectly aligned. The coupling allows for a small amount of misalignment between the two shafts, while still transmitting torque between them.
Conclusion
In conclusion, the Oldham's coupling is a type of coupling that is used to connect two parallel shafts. It is the third inversion of the double slider crank chain, and it allows for a small amount of misalignment between the two shafts.
