Enter the maximum load on the pulley (N) and the radius of the pulley (m) into the calculator to determine the Load Torque. 

Load Torque Formula

The following formula is used to calculate the Load Torque. 

LT = ML * RP
  • Where LT is the Load Torque (N-m)
  • ML is the maximum load on the pulley (N) 
  • RP is the radius of the pulley (m) 

To calculate the load torque, multiply the maximum load on the pulley by the pulley radius.

How to Calculate Load Torque?

The following two example problems outline how to calculate the Load Torque.

Example Problem #1:

  1. First, determine the maximum load on the pulley (N). In this example, the maximum load on the pulley (N) is measured to be 40.
  2. Next, determine the radius of the pulley (m). For this problem, the radius of the pulley (m) is calculated to be 40.
  3. Finally, calculate the Load Torque using the formula above: 

LT = ML * RP

Inserting the values from above and solving the equation with the imputed values gives: 

LT = 40 * 40 = 1600 (N-m)


FAQ

What factors can affect the Load Torque of a pulley system?

The Load Torque of a pulley system can be affected by several factors including the friction between the pulley and the belt, the efficiency of the pulley system, the weight distribution of the load, and the material properties of both the pulley and the belt.

How can you increase the Load Torque in a pulley system?

To increase the Load Torque in a pulley system, you can either increase the maximum load on the pulley or increase the radius of the pulley. Additionally, optimizing the system for minimal friction and using materials that can handle higher loads can also contribute to an increase in Load Torque.

Are there any limitations to the Load Torque formula?

Yes, the Load Torque formula assumes ideal conditions without accounting for factors such as friction, pulley deformation, or belt slippage. In real-world applications, these factors can significantly affect the actual Load Torque, and adjustments may be necessary for accurate calculations.
