Torque to speed reduction ratio

  1. Jan 27, 2009 #1
    hi,I was wondering if anybody would know the following:

    If I have a 200hp motor that has 600ft/lbs of torque at 1750 rpm
    and reduce the speed to 190 rpm with pulleys 9.2:1 does that
    give me 600ft/lbs x 9.2 = 5520 ft/lbs torque @ 190 rpms?

    Yes, minus losses due to friction in the pulley system.
