ClassX Video Lessons Youtube Channel The Engineering Mindset Pulley Belt CALCULATIONS – Belt length, distance between pulley wheels
Welcome to an insightful exploration of pulley belt calculations, inspired by the content from TheEngineeringMindset.com. In this discussion, we will delve into the essential calculations needed to determine the belt length and the distance between pulleys in a pulley system. This knowledge is particularly useful in various applications, such as air handling units, pumps, and conveyor belts in manufacturing.
In our example, we have an induction motor connected to two pulleys via a belt, which drives a centrifugal fan. This setup is common in many industrial applications. The primary focus will be on two critical calculations: the length of the belt and the distance between the two pulleys. These calculations are vital for both existing installations and new designs.
To determine the total length of the belt connecting the induction motor to the centrifugal fan, we need to know the sizes of both pulleys. This information can be obtained from manufacturer data or by direct measurement. Typically, the first pulley is the larger one in the system.
Additionally, we need to know the center-to-center distance between the two pulleys, denoted as “C-C.” The formula for calculating the belt length might appear complex, but it becomes straightforward when broken down into steps. By substituting the known values into the formula, we find that the belt length is approximately 1,675 millimeters or 65.96 inches.
Next, we calculate the center distance between the two pulleys. For this calculation, we need the diameters of both pulleys and the belt length. The formula for this calculation is more intricate, but by following a systematic approach, we can determine the center distance.
Using metric units, after substituting the values and performing the calculations, we find that the center distance is 600 millimeters. When using imperial units, the same formula and approach yield a center distance of approximately 23.6 inches.
While these calculations may initially seem daunting, they become manageable with a methodical approach. For practical applications, using spreadsheet software like Excel can enhance efficiency and accuracy in performing these calculations.
Understanding and applying these pulley belt calculations is crucial for designing and maintaining efficient pulley systems. By mastering these calculations, you can ensure optimal performance in various industrial applications. For further insights and resources, visit TheEngineeringMindset.com.

Hello everyone, Paul here from TheEngineeringMindset.com. In this video, we will be discussing some calculations related to belts in a pulley system. For our example, we have an induction motor connected via a belt to two pulleys, which drive a centrifugal fan. This setup is common in various applications, such as air handling units (AHUs), pumps, and conveyor belts in manufacturing.
We will focus on two main calculations: the length of the belt and the distance between the two pulleys. These calculations can be useful for both existing installations and design purposes. If you know the distance between the pulleys and the size of the pulleys, you can calculate the required belt length. Conversely, if you know the belt length and the diameters of the pulleys, you can determine the appropriate distance between them.
Please note that while these calculations provide a good estimate, the actual measurements may vary slightly in real-world scenarios. Now, let’s dive into the calculations.
First, we will calculate the belt length. In our example, we want to find the total length of the belt connecting the induction motor to the centrifugal fan. We need to know the sizes of both pulleys, which can be obtained from manufacturer data or by measuring them directly. Remember, the first pulley is always the larger one.
We also need to know the center distance between the two pulleys. I will use some symbols commonly used in engineering: “D” for diameter and “C-C” for center-to-center distance.
The formula for calculating the belt length may look complex, but it’s straightforward once you break it down. I have color-coded the numbers for clarity and provided both metric and imperial units for your convenience.
After substituting the values into the formula and performing the necessary calculations, we find that the length of the belt is approximately 1,675 millimeters or 65.96 inches.
Next, we will calculate the center distance between the two pulleys, starting with the metric version. For this calculation, we need the diameters of both pulleys and the belt length, but we do not yet know the distance between the pulleys.
The formula for this calculation is a bit more complex, but we will go through it step by step. After substituting the values and performing the calculations, we find that the center distance between the two pulleys is 600 millimeters.
Now, let’s perform the same calculation using imperial units. The formula remains the same, and we will follow the same step-by-step approach. After substituting the values and completing the calculations, we find that the center distance between the two pulleys is approximately 23.6 inches.
As you can see, while the calculations may seem complicated at first, they are manageable with a systematic approach. For efficiency, I recommend using spreadsheet software like Excel for these calculations, especially for practical applications.
