Min torque rating for a gear and pinion

  1. Feb 26, 2012 #1
    I have a pinion exposed to 100 oz-in torque and a gear exposed to 300 oz-in of torque (gear ratio of 3).
    Does the pinion need to have a torque rating above 100 or 300 oz-in?

    Each component has a maximum load rating -- make sure the load on each separate component does not exceed the rating and your design should not fail. You may also want to add a factor of safety to account for possible overloading.

    So theoretically, will the pinion break if sized for a torque rating of 100 oz-in? (I'd probably use a FOS of 1.5 or 2 though)
