Enter the belt speed and the RPM into the calculator to determine the sheave diameter. This calculator helps in designing belt drive systems and ensures proper sheave selection.
Sheave Diameter Formula
The following formula is used to calculate the sheave diameter.
D = {V}/[{pi * RPM}/{12}]Variables:
- D is the sheave diameter (inches)
- V is the belt speed (feet per minute)
- RPM is the revolutions per minute of the sheave
To calculate the sheave diameter, divide the belt speed by the RPM adjusted for units (RPM multiplied by π and divided by 12 to convert to feet).
What is a Sheave Diameter?
Sheave diameter is a critical dimension in belt drive systems. It is the diameter of the sheave, or pulley, over which a belt runs. The sheave diameter, along with the belt speed and RPM, determines the mechanical advantage and efficiency of the belt drive system. Proper sheave sizing is essential for optimal performance and longevity of the belt and sheave.
How to Calculate Sheave Diameter?
The following steps outline how to calculate the Sheave Diameter.
- First, determine the belt speed (V) in feet per minute.
- Next, determine the RPM (revolutions per minute) of the sheave.
- Next, gather the formula from above = D = V / (π * RPM / 12).
- Finally, calculate the Sheave Diameter (D) in inches.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
belt speed (V) = 1000 feet per minute
RPM (revolutions per minute) = 1200 RPM
