Torque Relationship Calculator

Torque on the driven gear (T_driven):

Torque of teeth on the driving gear (T_driver):

Gear Ratio (i):

How This Is Calculated

$$ T_{driven} = T_{driver} \cdot i $$ where:

T_driven = Torque on the driven gear (Nm)

T_driver = Torque of teeth on the driving gear (Nm)

i = Gear Ratio (Dimensionless)

Assumptions

There are no energy losses (the gears are ideal).
The gears are rigid and do not deform under load.
The gear ratio remains constant.
Backlash is negligible.
