How would one go about calculating the applied force of an arbor press assuming one knows the input torque to the pinion?

Recommended for you

The input torque divided by the pinion pitch radius should give you the force on a simple gear and rack arbor press. Keep your units consistant.

xdoug92000,

Don't forget to account for mechanical (friction) losses at the bearing points.

Does your press have it's leverage ratio printed or stamped into it's name-tag? If it was for example, 25:1 then for every one unit input there would be 25 units of output.

An easier way to do it might be to just measure the direct motion ratio.

Lever travel divided by actual measured stroke.
 
Hang a five pound(kilo) weight from the arm and measure delivered force. You will need to know how far out the weight is positioned.
