    Higher reaction torque than input value

    David Flemming

      Hello everyone...


      I'm running a simple analysis to measure the torque transmitted to a contact patch on a wheel in SW Simulation. In the image below I apply a 134 Nm torque to the shaft face about its axis, the shaft transmits torque to the wheel which has a fixed patch at its base.


      The problem is that when I'm checking the reaction forces and torque, I'm getting a torque of 138 Nm.


      I expected to get a bit less since the contact definition of the gear teeth is No Penetration with 0.2 coefficient of friction. So I'm wondering if it's just a margin of error or something.


      In the image below, the torque is measured from a point on the axis

      I've attached the Assembly as well.


      Any help will be greatly appreciated

      Kind Regards,
