Transfer of torque - wheel to wheel contact

  1. Oct 5, 2009 #1
    Hi all,

    I am trying to calculate the the torque of a system which uses various size wheels to transfer power.


    A motor, of 100Nm torque, 40000 rpm, has a shaft of 7mm diameter in contact with a wheel 20mm in diameter. This wheel is in contact with a 15mm wheel.

    I need to work out the torque of the 15mm wheel.

    Any help would be much appreciated.

    Assuming no slip between the wheels you treat them like gear/pulleys.

    Do you know how to work out the change in torque on pulleys or gears?

    That's the route I have been travelling down but wasnt sure if that was correct.

    Is it possible to include slip?
