Universal coupling also called as universal joint shaft or U-joint is a
joint that is used to join two rods which are inclined to each other at their
axes. This coupling is mostly used in shafts that used to transmit rotary
motion or power. It is actually pair of
things put close to each other inclined at 90ᵒ and connected by universal
shaft.

Universal joint shaft is made
up of several parts including Collar, Pin, Fork, Taper Pin and Central Block.
Shaft and Shaft key are not actually integrated in universal joint but are
required to complete the assembly of the joint.
The Universal joint is connected to the different parts
of the machine via drive shaft. Centre block in the universal joint serves a
role of basic building block by supporting the forks used in joint. Centre
block is nothing but two hollow cylinders perpendicularly joined with each
other. Holes in the Cylinders help in accommodation of pins.
In order to provide support to shaft two forks are
used. Fork consists of a hole at centre to support shaft. Additionally it consists
of two more holes to support a pin. The centered hole in the fork also supports
a key-way to accommodate shaft key. A Pin
secures the fork to the centre block and contains a tapered hole to accommodate
taper pin. As similar to forks there is also a pair of pins to support two
forks in shaft.
