Hello guys, I am new here =)(adsbygoogle = window.adsbygoogle || []).push({});

After looking everywhere on Google, I have decided to create an account and give this a shot!

I am trying to understand the concept of Torque generated by a gear box (simple gearbox with 2/3 gears, nothing fancy). I understand that changing the gear ratio changes the Torque of a gear box. More specifically, one creates a reduction gearbox, the Torque increases.

Ok then, now I am wondering:

Keeping in mind this formula:

T = I [tex]\alpha[/tex]

where T= Torque, I = moment of Inertia, and [tex]\alpha[/tex] = angular acceleration

Does it mean that if one changes the moment of Inertia of a gear the Torque changes too?!

More specifically, does it mean that one could increase the Torque being produced by a gearbox by simply increasing the Area/Size of the gears itself (with no need of changing the ratio)?

Thank you for your time, and please let me know if I need to make this any clearer!

Regards

N19!

# Is it possible to change the Torque in a gearbox by altering the inertia?
