    Gear pitch is "...the distance between equivalent points on adjacent teeth".

    Google->wiki:idler gear=An intermediate gear which does not drive a shaft to perform any work is called an idler gear.
    Idlers are typically used to reverse the drive direction to another gear.

    32 pitch gears with 32 teeth have a 1" pitch diameter.
    pitch diameter is the diameter of a gear where the optimum force transfer takes place. its usually right about halfway down the tooth face.
