3.  Coupling and clutches are power transmission
elements .
 Coupling is Used for transmitting power from
one shaft to another shaft.
The break is a fractional device whose primary
function is to control the motion of machine
member.
Break is device used to bring machine member
Into rest or slow down.

4. Couplings
 A coupling is a device used to connect two shaft
Shaft are mostly available for 7 meters length
due to
transport difficultly. To get a greater length , it is
necessary to joint two or more pieces of the shaft
using coupling.

5. Types of couplings
1. Rigid coupling
2. Flexible Coupling

6. 1. Rigid coupling
 It is used to connect two shafts which are
perfectly in
axial Alignment . There are basic three types
of rigid
coupling as followsA. Sleeve or muff coupling
B. Clamp or split muff
C. Flange coupling

7. A.Sleeve or muff
coupling

8. B. Clamp or split muff

9. C. Flange coupling

10. 2.Flexible Coupling
 This coupling is used to protect the driven and
driven
machine members again effect produce due to
misalignment of shaft , vibration , sudden
shock load
or shaft expansion. There are basic three types
of
flexible couplingA. Bushed pin type flange coupling
B. Universal Coupling
C. Oldham coupling

11. A. Bushed pin type flange
coupling

12. B. Universal Coupling

13. C. Oldham coupling

14. Clutches
Clutches is device which facilitate engage and
disengage of driving shaft and driven shaft
whenever
required .There are Two types of Mechanical
Clutches
1. Friction Clutches
2. Positive contact
clutches

15. 1. Friction Clutches
A friction clutches is used to transmission of
power between two machines shafts which may be
required to stop or start frequently .
In automobile ,friction clutches is used to connect
the engine to the driven shaft . In operation such a
clutch , care should taken so that the friction
surface engage easily and gradually brings the
driven to proper speed.

16. Types of Friction
clutches
A. Disc clutch
B. Cone clutch
C. Centrifugal clutch

17. A. Disc

19. C. Centrifugal
clutch

20. Positive contact
clutch
This type of clutch engaged or disengaged without
slip. Therefore it known as positive contact clutch.
This clutch is not suitable where gradual
engagement and disengagement is required
without stopping the driving shaft.

21. Jaw clutch (Positive contact
clutch)

22. Brakes
A brake is a mechanical device which produces
frictional resistance against moving machine
member , in order to slow or stop the motion of
machine.
There are four types of brake.
A. Block brake
B. Band brake
C. Internal expanding shoe brake
D. Disc brake

23. A. Block brake

24. B. Band Brake

25. C . Internal Expanding shoe brake

26. D. Disc brake
