Procedure 3: Calculation of Speed Ratio
Determine the speed ratio from either of the following equations.
Speed Ratio = Faster Sheave’s rpm
Slower Sheave’s rpm
or
Speed Ratio =
Large Sheave’s Outer Diameter
Small Sheave’s Outer Diameter
The following procedure applies to Power Ace,
Power Ace Combo, Power Ace Cog and Power
Ace Cog Combo.
Example: Customer needs a V-belt drive for an agitator
that is in operation continuously.
Driving Motor: 5 Hp @ 900 RPM, Outer Datum Diameter 3.0"
DriveN Sheave: 250 RPM
Center Distance: 32"
Procedure 4: Selection of Sheave Combination
Using table 2 below and the speed ratio, determine the sheave
combination. Choose one of the sheaves, preferably the faster,
from table 2 and calculate the outer diameter of the other sheave
using the speed ratio. Belt speeds in excess of 6500 rpm require
special sheaves. Consult the sheave manufacturer.
Design HP = Transmission HP x Service Factor
Design HP = 5 X 1.2 (from Table 1) = 6
Procedure 5: Selection of Belt Size
Using the given center distance and the size of the large and small
sheaves selected, calculate the belt length. For this purpose the
following equation is used.
Speed ratio = 900 = 3.6:1 ratio
250
Belt Size = 2C + 1.57 (D+d) +
(D-d)
The belt section according to design horsepower and
Fig. 1-> 3V
A 3.6:1 ratio is needed as per the formula below.
Select a 3.0" drive sheave and a 10.6" driveN sheave, or any
desired combination that achieves 3.6:1 ratio from Table 2.
If your center distance is known to be 32 inches then:
2
4C
Belt Size = 2(32) + 1.57(10.6+3) + (10.6-3)² = 85.8"
4(32)
C = Center Distance
D = Outer Diameter of Large Sheave
d = Outer Diameter of Small Sheave
Select nearest available belt size from the catalog. The
3V850 has the closest datum length and should be used
in this circumstance.

POWER ACE DRIVE SELECTION
Procedure 8: Check the Center Distance Adjustment
Determine the minimum center distance allowance for installation and tensioning from Table 6.
Fig. 2
Example cont.
Determine the Base HP rating and speed ratio adder from the HP ratings
charts. Table 3 provides the appropriate page # and table # for the HP
ratings charts.
For a 3V belt running on 3.0" diameter sheave @ 900 RPM.
Standard Transmission HP = Base HP ratings + Speed Ratio Adder
Standard Transmission = 1.34 (Table 7) + .20 (Table 8) = 1.54
# of Belts =
Design HP
Standard Transmission HP x Coefficient of x
Arc of Contact
(see Table 4)
=
Coefficient of
Belt Length
(see Table 5)
6
(1.54x0.97x1.06)
=
3.8 ~ 4
Therefore, 4-3V850 belts are to be used in this drive.

POWER KING DRIVE SELECTION
Procedure 1: Calculation of Design Horsepower
Calculate the design horsepower from the following equation.
Design Horsepower = Transmission Horsepower x Service Factor
Refer to the driveN machines listed in Table 1 on page 3 and select the corresponding service factor.
Procedure 2. Selection of Belt Section
From Figure 3, select the belt section according to the transmission horsepower computed using Procedure 1 and
the faster sheave's rpm.

Procedure 3: Calculation of Speed Ratio
Determine the speed ratio from either of the following equations.
Speed Ratio =
Faster Sheave's rpm
Slower Sheave's rpm
or
Speed Ratio =
Large Sheave's Datum Diameter
Small Sheave's Datum Diameter
Procedure 4. Selection of Sheave Combination
Using Table 17 below and the speed ratio, determine the pulley combination. Choose one of the sheaves, preferably the
faster, from Table 17 and calculate the outer diameter of the
other sheave using the speed ratio.
The following procedure applies to Power King, Power King
Combo, Power King Cog and Power King Cog Combo.
Example: Customer needs a V-belt drive for a crusher that
is in operation continuously.
Driving motor: 15 Hp @ 400 RPM
Driven pulley: 300 RPM, Datum Diameter 12.4"
Center Distance: 45.8
Design HP = Transmission HP x Service Factor
Design HP = 15 x 1.8 (from Table 1) = 27
The belt section according to design horsepower and Fig. 3-> B
A 1.33:1 ratio is needed as per the formula below.
Speed ratio =
Procedure 5. Selection of Belt Size
Using the given center distance and the size of the large and
small sheaves selected, calculate the belt length. For this purpose the following equation is used.
(D-d)2
Belt size = 2C + 1.57 (D+d) +
4C
C = Center Distance
D = Datum Diameter of Large Sheave
d = Datum Diameter of Small Sheave
400 = 1.33:1 ratio
300
Select a 9.4" drive sheave and a 12.4" driven sheave, or any
desired combination that achieves 1.33:1 ratio from Table 17.
If your center distance is known to be 45.8 inches then:
Belt size = 2(45.8) + 1.57(12.4+9.4) + (12.4-9.4)² = 125.8"
4(45.8)
Select nearest available belt size from the catalog. The B124 has
the closest datum length and should be used in this circumstance.

POWER KING DRIVE SELECTION
Procedure 8: Check the Center Distance Adjustment
Determine the minimum center distance allowance for installation & tensioning from Table 20.
Fig. 4
Example cont.
Determine the Base HP rating and speed ratio adder from the HP ratings
charts. Table 18 provides the appropriate page # and table # for the HP
raings charts.
For B belt running on 9.4" diameter sheave @ 400 RPM
Standard Transmission HP = Base HP ratings + Speed Ratio Adder
Starndard Transmission = 5.03 (Table 24) + .20 (Table 25) = 5.23
# of Belts =
Design HP
Standard Transmission HP x Coefficient of
Arc of Contact
(see Table 19)
=
x
27
(5.23x0.99x1.09)
Coefficient of
Belt Length
(see Table 20)
= 4.78 ~ 5
Therefore, 5- B124 belts are to be used in this drive.
