EXAMPLE DRIVE CALCULATION
STEP 3 - Selection of Belt, Pulleys and Center Distance
Step 3-a) Speed Ratio From Formula [3] SR = 1.75
• n f from Basic Drive Data
• n s from Basic Drive Data
Step 3-b) Belt, Pulleys and From Center Distance Table Z 1 = 32 teeth
Center Distance • Center Distance from d p = 3.208 inches
Basic Drive Data
Z 2 = 56 teeth
• SR from Step 3-a
D p = 5.614 inches
C = 24.54 inches
L p = 1600 mm
Z b = 200 teeth
Step 3-c) Check belt/pulley tooth Z b /Z 1 & Z b /Z 2 Z b /Z 1 = 6.25
ratio as an integer • Z 1 from Step 3-b Z b /Z 2 = 3.57
• Z 2 from Step 3-b
• Z b from Step 3-b
STEP 4 - Determine the Belt Width Needed
Step 4-a) Basic Performance P a From Horsepower Ratings Table P a = 29.13 hp
(22 mm width)
• Z 1 from Step 3-b
• n f from Basic Drive Data
Step 4-b) Calculation of K z From Formula [4] & Table 4 K z = 1.0
• D p from Step 3-b
• d p from Step 3-b
• C from Step 3-b
• Z 1 from Step 3-b
• Z t from Formula [4]
Step 4-c) Calculation of K L From Table 5 K L = 1.13
• L p from Step 3-b
Step 4-d) Verify Actual Power Rating From Formula [5] P ba = 32.92 hp
• P a from Step 4-a
• K z from Step 4-b
• K L from Step 4-c
P ba > P d
22mm width is OK
