3. WHAT IS CLUTCH
 A clutch is a mechanical device which engages and disengages
power transmission especially from driving shaft to driven shaft.
 In the simplest application, clutches connect and disconnect two
rotating shafts (drive shafts or line shafts). In these devices, one
shaft is typically attached to an engine or other power unit (the
driving member) while the other shaft (the driven member)
provides output power for work. While typically the motions
involved are rotary, linear clutches are also possible.

4. PRINCIPAL:
 It operates on the principal of friction. When two surfaces are
brought in contact and are held against each other due to
friction between then, they can be used to transmit power. If
one is rotated then other is also rotates.

5. TYPES OF CLUTCHES
 Cone clutch.
 Semi-centrifugal clutch.
 Centrifugal clutch.
 Friction clutches

6. CONE CLUTCH:
 A cone clutch serves the
same purpose as a disk or
plate clutch. However,
instead of mating two
spinning disks, the cone
clutch uses two conical
surfaces to
transmit torque by
friction.
 The cone clutch transfers a
higher torque than plate
or disk clutches of the
same size due to the
wedging action and
increased surface area.
Cone clutches are
generally now only used
in low peripheral speed
applications although
they were once common
in automobiles and other
combustion
engine transmissions.

7. SEMI-CENTRIFUGUAL CLUTCH:
 A centrifugal clutch is a clutch that
uses centrifugal force to
connect two concentric shafts,
with the driving shaft nested
inside the driven shaft. It
engages more at higher
speeds. The input of
the clutch is connected to the
engine crankshaft while the
output may drive a shaft,
chain, or belt.

8. CENTRIFUGAL CLUTCH:
 A centrifugal clutch is a clutch that
uses centrifugal force to
connect two concentric shafts,
with the driving shaft nested
inside the driven shaft. It
engages more at higher
speeds.

9. FRICTION CLUTCH:
 A friction clutch in which
the frictional surfaces are disks.
slip clutch, slip friction clutch.
a friction clutch that will slip
when the torque is too great.
Type of: clutch. a coupling that
connects or disconnects driving
and driven parts of a driving
mechanism.

10. WORKING OF CLUTCH:
 Running through the centre of the pressure plate, clutch disc and
flywheel is the input shaft of the transmission. The shaft takes the
input, or power of the engine, and sends it down through the
gears to the wheels. ... The input shaft is what the clutch disc itself
is connected to.
