The formula to calculate the Total Length of Belt is:
\[ L_{belt} = \pi (r_2 + r_1) + 2x + \frac{(r_1 - r_2)^2}{x} \]
Total Length of Belt is the length of the belt in the belt drive. Radii of Smaller Pulley is a straight line from the center to the circumference of the smaller pulley. Radii of Larger Pulley is a straight line from the center to the circumference of the larger pulley. Distance Between Centers of Two Pulleys is the horizontal distance between the larger and smaller pulley.
Let's assume the following values:
Using the formula:
\[ L_{belt} = \pi (6 + 10) + 2 \cdot 0.55 + \frac{(10 - 6)^2}{0.55} = 80.4563915483458 \]
