Coupling is one kind of mechanical device which is used to connect two shafts together at their
ends for the purpose of transmitting power.
The primary purpose of couplings is to join two pieces of rotating equipment while permitting
some degree of misalignment or end movement or both.
A rigid coupling is a unit of hardware used to join two shafts within a motor or mechanical system.
It may be used to connect two separate systems, such as a motor and a generator, or to repair a
connection within a single system. A rigid coupling may also be added between shafts to reduce
shock and wear at the point where the shafts meet.
Flanged coupling is a type of rigid coupling in which two co-linear shafts are connected by the
flanges. The coupling enables torque transmission between the shafts & prevents relative rotation
between them.
In the project work a flanged coupling was made by local material available & the analysis of
various stresses & safety factor was also performed.
The outcome of analysis is there’s no danger of failure by pure shear, even if a fatigue strength
reduction factor is included, but this same section may have severe & undefinable bending stresses
on it if the flanges are imperfectly aligned, and they surely will be. The bolts bending was neglected
since they were too small compared to the result outcome.
Finally, the computed factor of safety of the flanges suggest that it would withstand repeated
bending if the misalignment is small.

The gears are a type of mechanical element whose teeth are cut around a cylindrical or conical surface with the same space. It is used for the rotation and transmission of force from the drive shaft to the driven shaft when coupling a pair of elements. The gears can be classified into spiral, cycloid and trochoidal gears according to their shape. It can also be classified as parallel shaft gear, transverse shaft gear and non-parallel and non-transverse shaft gear depending on the position of the shaft.
This presentation briefly tells about the classification of Gears. It includes information about spur, helical, bevel, herringbone, rack and pinion, internal and external gears.

2. Couplings
• A device that is used to connect two shafts
together for the purpose of power
transmission.
• General types of couplings are:
–rigid: for aligned shafts
–flexible: for non-aligned shafts
3. Aligned Shaft Couplings
• Aligned shaft couplings are rigid couplings
that are designed to draw two shafts
together so that no motion can occur
between them.
• Types
–Flanged
–Split Coupler
–Keyed
–Friction
4. Flanged Coupling
A key is used to to fix the coupling to the
shaft, and then couplings are bolted
together.
5. Split Coupler
Again, a key is used to fix the coupling
and the shaft and the two halves of the
coupling are bolted together.
6. Keyed Coupler
•Grooves are cut into the shaft and the
fixed part.
•A key is put in the grooves to lock the
two parts together.

8. Non-Aligned Shaft Couplings
• Used to join shafts that meet at a slight
angle.
• Angle may still change while running due
to vibration or load.
• Types:
–Universal
–Constant Velocity
–Flexible
9. Universal Joint
•Consist of two end yokes and a center bearing
block.
•Provides for angular misalignment of up to 45
degrees.
10. Constant Velocity Joint
•Used where angles are greater than 20 and there
is no room to use two universal joints.
•Driven shaft maintains a constant speed
regardless of driver shaft angle.
•Used on driveshafts on front wheel drive cars.
11. Flexible Coupling
•Both shafts are bolted to a rubber disc. The
flexibility of the disc compensates for the change
in angle.
•Can handle approximately 3 of angular
misalignment.
