Pulley Torque Calculator

Formula

The formula to calculate the Torque (T) acting on a pulley in a belt-drive system is:

\[ T = \frac{F \cdot r}{n} \]

Where:

\( T \) is the Torque (N*m).
\( F \) is the Force (N).
\( r \) is the Radius of the Drive Pulley (m).
\( n \) is the Efficiency of the System.

What is Pulley Torque?

Pulley torque is defined as the total torque acting on a drive pulley of a belt-drive system moving at a constant velocity. It is a measure of the rotational force applied to the pulley.

Example Calculation

Consider an example where:

Force (F): 100 N
Radius of the Drive Pulley (r): 0.5 m
Efficiency (n): 0.9

Using the formula to calculate the Torque:

\[ T = \frac{100 \cdot 0.5}{0.9} = 55.56 \text{ N*m} \]

This means that the torque for this example is approximately 55.56 N*m.
