Flanged Coupling

It is a very widely used rigid coupling and consists of two flanges keyed to the shafts and bolted.
Historical Background:
In 1545, Italian mathematician Girolamo Cardano theorized that the principal of gimbals could be used to transmit rotary motion through an angled connection, which was developed into the Cardan Shaft, which was said to deliver a smoother ride, along with being more efficient and less prone to breakdowns because the shaft was always at a 90 degree angle to the axle. This new concept was actually first seen in 1548 on the carriage of the Holy Roman Emperor Charles the 5th.
Then in 1676, Robert Hooke revisited Cardano’s idea and used it to make an instrument that would allow for a safer way to study the sun. This new instrument used a new type of joint that allowed for twisting motion in one shaft to be passed on to another, no matter how the two shafts were oriented. It would take another 240 years for Clarence W. Spicer to come along and apply this idea to the automotive and industrial industries. Spicer received a patent for the universal joint in 1903 and demonstrated his new patent in a self-designed car, which did not have a troublesome chain & sprocket nor did it have chain and geared adaptions. Spicer would then begin manufacturing in 1904.
Human invented the transformation of energy. Soon they learnt to transfer it using shaft. But in many cases they were unable to transfer power by shafts due to misalignment, length of the shaft & its bending property. So they tried hard & invented the way of transmitting power by shafts in all possible situations. The mechanical joint they invented was named coupling.
