What is Belt Length?

Belt length is the total length of the belt that wraps around two pulleys in a system. It’s important to ensure the belt fits and works properly in mechanical systems like conveyors and engines.

How to Use the Calculator

To use the calculator, follow these steps:

  1. Enter the diameter of the larger pulley into the field labeled “Diameter of larger pulley.”
  2. Enter the diameter of the smaller pulley into the field labeled “Diameter of smaller pulley.”
  3. Enter the distance between the pulleys into the field labeled “Length Between Pulleys.”
  4. Click on the “Calculate” button to find the belt length.

Example Input Values:

  • Diameter of larger pulley: 10 cm
  • Diameter of smaller pulley: 5 cm
  • Distance between pulleys: 20 cm

How to Calculate Belt Length

The formula to calculate the belt length is:

Formula:

BL=((DL+DS)×π2)+(2×L)+((DLDS)24×L)BL = \left( \frac{(DL + DS) \times \pi}{2} \right) + (2 \times L) + \left( \frac{(DL – DS)^2}{4 \times L} \right)

Variable:

BL  is the belt length
DL  is the diameter of the larger pulley
DS  is the diameter of the smaller pulley
L  is the distance between the pulleys

Example Calculation

To, calculate the belt length step-by-step using the example values:

  • Diameter of larger pulley (DL): 10 cm
  • Diameter of smaller pulley (DS): 5 cm
  • Distance between pulleys (L): 20 cm

First, calculate the first part of the formula:

((DL+DS)×π2)=((10+5)×π2)=(15×3.142)=23.55 cm

Next, calculate the second part of the formula:

(2×L)=(2×20)=40 cm(2 \times L) = (2 \times 20) = 40 \text{ cm}

Then, calculate the third part of the formula:

((DLDS)24×L)=((105)24×20)=(2580)=0.3125 cm\left( \frac{(DL – DS)^2}{4 \times L} \right) = \left( \frac{(10 – 5)^2}{4 \times 20} \right) = \left( \frac{25}{80} \right) = 0.3125 \text{ cm}

Finally, add all parts together:

BL=23.55+40+0.3125=63.8625 cmBL = 23.55 + 40 + 0.3125 = 63.8625 \text{ cm}
