Designing Elevation Gearbox for Heavy Loads (100 N Force)

[nevets48]

Hi,
I am tasked to design an elevation gearbox that will enable the operator to achieve precise elevation motion of a heavy load (700 to 800 kilograms) with manual force of about 100 N.

As the load is heavy and accuracy required, is it correct that I will need a gear reducing gearbox to act as a torque mulitplier?

I have the weight of the load and the ideal input force (100 N; to prevent fatigue of operator), but I do not know how to derive the gear ratio required for the gearbox.

Will appreciate if I can get any suggestions and help here.

Thanks!

Yes, a gearbox with a gear reduction ratio is the best option for your application. To calculate the gear ratio you need to know the torque required to move the load and the input torque you have available. The gear ratio is then equal to the output torque divided by the input torque. For example, if you need 600 Nm of torque to move the load but only have 100 Nm available, the gear ratio would be 6:1.
