3. introduction
 In the present scenario power becomes major need for human
life.
 Due to day-to-day increase in population and lessen of the
conventional sources, it becomes necessary that we must
depend on non-conventional sources for power generation
 While moving, the vehicles posses some kinetic energy and it is
being wasted.
 This kinetic energy can be utilized to produce power by using a
special arrangement called “POWER HUMP”.
 The Kinetic energy of moving vehicles can be converted into
mechanical energy of the shaft through rack and pinion
mechanism.
 So, the power can be generated.

4. Speed Breakers is used for decreasing speed of any vehicles.
Speed Breakers put in to the mid of the road, where there more
traffic are possible, or in crowded area. To reduce the
possibility of accident by reducing speed of vehicles.
WHAT IS SPEED BREAKERs?

5. HOW IT CAN BE USEDFOR POWER
GENERATION?
Generally, the vehicles are moving from on speed breakers.
When the vehicle pass through the speed breaker, if there mechanical
mechanism put in speed breaker, the breaker press down due to the
weight and kinetic velocity of vehicle.
So, by the help of mechanical mechanism…Power can be generated.
And the speed breakers can used for power generation.

6.  Rack-pinion
 Large and small sprockets
 Chain & Shaft
 Flywheel
 Small & Large Gear
 Generator
 Ball Bearing
Component

7. BASIC PRINICIPLE
 Simply, Weight (potential energy) and kinetic energy
conversion into mechanical energy.
 And again mechanical energy conversion into electrical
energy.
Possible using 3 different mechanism:
1. Crank-shaft mechanism.
2. Roller mechanism.
3. Rack-pinion mechanism.

8.  Crank-shaft are required to be mounted on bearings which
creates balancing problem leading to mechanical vibrations
which in turn damage the bearings.
Secondly as bearing are of sliding type, any occurrence of
variable load (which is bit obvious in case of vehicles) leads to
balancing problem.
WHY using RACK-PINION MECHANISM...?

9.  Roller mechanism has some different disadvantages.
 Maintenance will be very difficult.
 Might cause collision.
ROLLER MECHANISM

10. DESIGN OF RACK-PINION
 A Rack and Pinion gears system is composed of two gears.
The normal round gear is a pinion gear and the straight and the
flat gear is the rack.
 The rack has teeth cut into it and they mesh with the teeth of
the pinion gear.

11. BLOCK DIAGRAM

12. CONSTRUCTION

13.  This project explains the mechanism of electricity generation from speed
breakers.
 The vehicle load acted upon the speed breaker system is transmitted to
rack and pinion arrangements.
 Then, reciprocating motion of the speed-breaker is converted into rotary
motion using the rack and pinion arrangement where the axis of the
pinion is coupled with the sprocket arrangement.
 The sprocket arrangement is made of two sprockets. One of the sprocket
is larger in dimension than the other sprocket.
WORKING

14.  Both the sprockets are connected with chain which transmits the
power from the larger sprocket to the smaller sprocket.
 As the power is transmitted from the larger sprockets to the
smaller sprocket, the speed that is available at the larger sprocket
is relatively multiplied at the rotation of the smaller sprocket.
 The axis of the smaller sprocket is coupled to a gear arrangement.
Here we have two gears with different dimensions. The gear wheel
with the larger diameter is coupled to the axis of the smaller
sprocket.
Hence, the speed that has been increased at the smaller sprocket
wheel is passed on to this gear wheel of larger diameter.

15.  The smaller gear is coupled to the larger gear. Therefore, as the larger
gear rotates it increases the speed of the smaller gear which is following
the larger gear and multiplies the speed to more intensity.
 Though the speed due to the rotary motion achieved at the larger
sprocket wheel is less, as the power is transmitted to gears, the final
speed achieved is high.
 This speed is sufficient to rotate the rotor of a generator and is fed into
the rotor of a generator.
 The rotor which rotates within a static magnetic stator cuts the
magnetic flux surrounding it, thus producing the electric motive force
(EMF).

16.  Maintenance and installation cost are low.
 Less floor area required.
 Pollution free power generation.
 No need of manpower during power generation.
 The project is easy to install.
 The project is eco-friendly.
ADVANTAGES

17.  Don’t want to see India as an energy deficient country.
 It should be of least cost, as well as of less weight.
 Efficiency should be as high as possible.
 Losses should be minimum.
OUR GOALS

18. FUTURE SCOPE
 The shortage of light can be reduced at some extant.
 Wastage of energy can be minimized.
 Flywheel can be used to increase the rotational speed of
the Dynamo shaft.
 It may also be used for light vehicle.

19. CONCLUSION
 It is an non conventional type of producing the
energy.
 Existing source of energy may not be adequate to
meet the ever increasing demands, So this project is a
one step to path off that way.
 This project will be helpful to solve some of the
Electricity shortage problems.
