__Input Torque Formula:__

The input torque formula is utilized to determine the torque required at the input of a mechanical system, such as a gearbox, to achieve a desired torque at the output, taking into account the gear ratio.

Input Torque, T_{i(N.m)} in Newton metres, is calculated by dividing the Output Torque, T_{o(N.m)} also in Newton metres, by the Gear Ratio, GR which is a dimensionless number.

Input Torque, T_{i(N.m)} = T_{o(N.m)} / GR.

T_{i(N.m)} = input torque in Newton metre, N.m.

T_{o(N.m) }= output torque in Newton metres, N.m.

GR = gear ratio.

__Input Torque Calculation:__

- Suppose you need an output torque of 600 N.m to drive a mechanical system and you have a gearbox with a gear ratio of 3:1. Calculate the input torque required.

Given: T_{o(N.m) }= 600N.m, GR = 3

Input Torque, T_{i(N.m)} = T_{o(N.m)} / GR.

T_{i(N.m) }= 600 / 3

T_{i(N.m)} = 200N.m.

- For a heavy-duty application, an input torque of 300 N.m is applied and the available gearbox has a gear ratio of 4:1. Find the output torque needed to meet this requirement.

Given: T_{i(N.m) }= 300N.m, GR = 4

Input Torque, T_{i(N.m)} = T_{o(N.m)} / GR.

T_{o(N.m) }= T_{i(N.m) }* GR

T_{o(N.m) }= 300 * 4

T_{o(N.m) }= 1200N.m.
