Coefficient of Friction in a V-Belt System -- Torque Changes?

  1. Mar 15, 2015 #1
    Can anyone explain why, if you increase the CoF of the belt on a V-Belt pulley system, you'd get less torque?

    I've increased my CoF in the V-Belt tension formula. You'd have thought that the torque would increase with a belt with a greater CoF?

    This equation? -

    Belt tension for V belts: F1/F2=e^((μθ)/sinα))

    Your intuition is right, as mu increases then F1/F2 increases so more torque for a given tight side belt tension - I suspect you've made a calculation error.

    Thanks again Billy, I'll double check calcs
