To calculate the proper distance between two pulleys given a specific belt size, you need to know the belt length and the diameters of the two pulleys. Here’s a step-by-step method to determine the center distance:
Belt Length (L): The total length of the timing belt.
Diameter of Pulley 1 (D1): Diameter of the first pulley.
Diameter of Pulley 2 (D2): Diameter of the second pulley.
This formula and method provide a good approximation for the center distance between pulleys for a given belt length. Adjustments may be necessary depending on the specific application and the flexibility of the belt.
The center distance between two pulleys can be calculated using the formula on the left where:
L is the total belt length,
D1 is the diameter of the first pulley,
D2 is the diameter of the second pulley,
π is approximately 3.14159.
