Input Torque Formula
The following formula is used to calculate the Input Torque.
Ti = To / GR
- Where Ti is the Input Torque (N-m)
- To is the output torque (N-m)
- GR is the gear ratio (Do/Di)
To calculate input torque, divide the output torque by the gear ratio.
How to Calculate Input Torque?
The following two example problems outline how to calculate the Input Torque.
Example Problem #1:
- First, determine the output torque (N-m). In this example, the output torque (N-m) is given as 100.
- Next, determine the gear ratio (Do/Di). For this problem, the gear ratio (Do/Di) is given as 5.
- Finally, calculate the Input Torque using the equation above:
Ti = To / GR
Inserting the values from above and solving the equation with the imputed values gives:
Ti = 100 / 5 = 20 (N-m)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
output torque (N-m) = 200
gear ratio (Do/Di) = 20
Entering these values yields:
Ti = 200 / 20 = 10 (N-m)
