WATER power | Learning about Gears
Every transmission system (gear train) contains gears. A gear is a useful and important transmission compo-
nent, as it is a transmission method that applies to two shafts, or between a wheel and a shaft.
You can observe the transmission of meshing gears inside old toys or old clocks. There is a gearbox within the
transmission system of cars, which combines meshing gears of different sizes. In this way, to change among
different speeds becomes easy.
Do you know how gears work? Please carefully read the descriptions below. You will learn the secrets of gear
trains from the world patent GIGO GEARS. The design of GIGO scientic educational building blocks ( that is
GIGO SCIENCE-TOOL KIT ) is based on the number of 10 and its multiples; whether on the size of the com-
ponents, the distance between the holes, or the unique GIGO gear tooth number. Therefore your child will be
able to not only correctly assemble the gears, but also conveniently calculate the gear ratio or change the rotary
speed. Different from other gear designs adopting the number of 8 or 7 as their fundamental number, GIGO
gears are created with perfect designs for the use of scientic teaching, and express the care on children and
passion for scientic education.
We suggest a gradual learning with GIGO gears which starts from the basic structures to understand the combi-
nations of each component. Once you nish your practice following the examples in this instruction, and possess
the fundamental concepts of gear trains, you can put your unlimited creativity into action and create various
vehicles or airplanes on your own. Let’s enjoy the pleasure of creativity!
The wheel which has many tooth-shaped objects sticking out of the rim with the same size is called a “gear”. Two
gears can mesh with each other with the teeth on the rims. When a gear rotates, the other one will be driven to
rotate as well. The intermeshing teeth of the two gears transmit rotation and torque.
A simple gear train uses two gears with the
same or different sizes. If one of these gears is
attached to a motor or a crank, it takes the role
as the driver gear. The gear that is turned by
the driver gear is called the driven gear. Gears
are used to increase or decrease the speed or
the power of rotary motion. The mechanism of
changing the speed or power is called the gear
ratio (speed ratio).
Fig. B
Illustration of gear ratio calculation
Fig. A
The intermeshing of gears
can effectively transmit ro-
tation. The red circle rep-
resents the actual diam-
eters of the transmission,
which is called the pitch
diameter. The tting shape
of the teeth assures the in-
termeshing and transmits
power along the pitch.

The secret of GIGO designs for gears is
to place the distance between each hole
based on 10 or the multiples. In Fig. E, the
distance between the centers of the two
gears is
and therefore the two gears can be
smoothly assembled or transmitted. Oth-
er sizes of GIGO gears are also designed
with the same perfect concept, and their
holes and gears can be greatly meshed
and operated with each other!
Learning about Gears | WATER power
The number of teeth between the big gear
and small gear is different. Despite the
teeth number or size of the gears, the teeth
of the gears in the same gear set should
have the same size. In simple gear trains,
the driver and driven gears will rotate in
opposite directions. When a third gear
is inserted between the driver gear and
driven gear, and makes them rotate in the
same direction, it is called an idler gear.
The world patent gears designed by GIGO
come in 5 different types: 20T, 40T, 60T,
80T, and 160T, the extra large gears.
Each of GIGO gear sets contains both
spur and bevel gears. Gears of HYDRO-
PNEUMATIC contain “Spur Gears” (gear
wheel to gear wheel) meshing in the same
plane and regulating speed or direction of
turning of the shafts and “Bevel Gears”
(the rounded off sections on one edge of
your gears in the set) meshed together
to change direction at right angles to the
initial turning plane of the gears and shafts
(axles).
The tooth shape of GIGO gears shares the
same speci cation of module pitches=1.
Namely, the pitch diameter of the 20T
gears is 20mm while the pitch diameter of
the 40T gears is 40mm. The pitch diame-
ters refer to the imaginary circles between
the meshed gear teeth as shown in Figure
E.

WATER power | Learning about Gears
1. Use two red 20-tooth gears and two yellow
60-tooth gears to make this system.
2. How many times do you have to turn the small
gear A in order to make the second large gear D
turn once?
The small gear A turning the large gear B gives a 3
to 1 ratio as you found out on the table.
The second small gear C is directly driven by the
arrangement and produces another 3 to 1 ratio
with the second large gear D.
Did you nd out that you had to turn the small gear
A 9 times to turn the second large gear D once?
The overall gear ratio of the system is 9 to 1. ( A
gear ratio of 3 to 1 multiplied by another 3 to 1 =
9 to 1).
3. Add a third red 20-tooth gear to the short drive
axle at (x). Why does it lock?
4. Add a blue 40-tooth and a red 20-tooth gear to the
system. Can you work out mathematically what the
gear ratio of system would be?
Count the number of turns. Were you right?
1. This gear box uses a combination of red 20-tooth
gears and yellow 60-tooth gears.
There are four pairs of red 20 and yellow 60-tooth
gears. Each pair produces a gear ratio of 3 to 1.
The overall gear ratio would then be 3 x 3 x 3 x 3
= 81.
If gear B is turned 81 times then gear A would turn
once.
2. If gear A could be turned once then gear B would
turn 81 times! Could you add another pair of gears
to make a ratio of 243 to 1?

Learning about Chain Gears | WATER power
1. The power transmission of chain gears depends on chains in-
stead of meshing each other. The teeth of chain gears must go
with chains. The “working” diameters of the chain gears are
about 10mm (10-tooth), 20mm (20-tooth) and 30mm (30-tooth).
Try to ensure that when connecting drive chains they are nei-
ther too tight nor too loose so that the motion of one is transmit-
ted efciently to the other. If the lengths can not exactly t the
distance a little looser will work better than a little tighter, only
that the drive chains come off the chain gears. This system can
be found in normal bikes or escalators.
2. Connect a 10-tooth chain gear to a 30-tooth chain gear as
shown.
3. Use a pencil point, or something similar, to turn B.
Which way does A turn?
Would this be the same if A and B were two gears in mesh?
How many times would you have to turn A for B to rotate once?
The gear ratio of these two chain gears would be _ to _ ?
4. Repeat the experiment for the two other arrangements and
make a table of your results for all three.
5. Try chaining a 10-tooth chain gear and two 30- tooth chain
gears together. Turn A clockwise.
What happens to B and C?
Do they turn in the same direction? Do they turn at the same
speed?
6. Try to chain the 10-tooth chain gear C as shown.
Turn A clockwise. What happens to B and C?
Do they turn in the same direction?
Do they turn at the same speed?
7. By connecting two sets of chain gears together three speeds
can be obtained.
This system is widely used in transmission bikes by adding a
gear shift in between.

FIXING BASE GRID, RODS AND FRAMES
FIXING GEARS
1. The peg can be used to join rods and
frames (Fig. 1).
2. Frames can be connected directly to
each other end to end (Fig. 2).
3. Using the end “A” of the peg/axle re-
mover to pull a peg off as Fig. 3 shows.
When  xing gears onto the frame with a drive axle,
be sure to keep a proper space (about 1mm) be-
tween the gears and the frames. Try to turn the gear
and con rm if every gear in the gear train can turn
smoothly so that the least friction will be created and
then the most ef cient power transmission can be
expected (Fig. 4 & 5).
When you use a power pack to drive a wheeled ve-
hicle, the gear wheels should be arranged in sym-
metry (the holes on the two opposite chain gear
wheels must be kept in a horizontal line) and be
kept at the same driven speed, or the motor will stall
and the vehicle won’t move (Fig. 8).

Gear fi xing
Gear  xings are designed
to prevent a pulley or gear
from moving along the
axle, or slipping. They are
easy to be installed with-
out removing any wheel or
axle (Fig. 6).
Meshing gears at 90°
When the two red gears
mesh with each other at 90°
the one on the drive axle
must be assembled as close
as possible to the outer end
of the axle so that the mesh
can be ensured (Fig. 9).
Use a chain gear to connect two drive axles to
lengthen when necessary (Fig. 7).
Lengthening drive axles Connecting unit chains
Ensure to get the face of each unit chain when con-
necting them to one another as a drive chain so
that the transmission can be done ef ciently and
smoothly (Fig. 10).

WATER power | Notes for assembly
1. NOTES FOR ASSEM-
BLY:
•Insert a 9.5cm long Tube A into
the protrudent hole on the re-
verse side of the lid of the Recy-
cled Water Storage, and cut its
the other end on the bias (Fig.
11). To attach the bias-cut end to
the inside bottom of the storage
so that water will easily enter the
hose when pumping.
•The lengths of hoses for the mod-
els given in this guide are for ref-
erence only. Be sure not to make
the hoses too tight nor twisted or
pressed (Fig. 12) in connection so
that water can go through them
smoothly.
•Put a Security Nut through a hose
and screw it completely when
connecting the hose to a secured
basic part (Fig. 13 & 14).
•Use an L Security Nut for Tube
A, and an S Security Nut for Tube
B. The hoses might become stub-
born and easily come off the con-
nected part after repeated use.
The solution is to cut off the stub-
born end about 1-1.5cm long. Be
sure to wipe the connected part
dry with tissue paper before the
refreshed hose is used again.
•The cut hoses can be repeatedly
used for different models.
