Crowning: A fix for noise reduction and misalignment on gears

Crowning also can reduce lead problems in the gears themselves, which causes the gears to wear unevenly and bind because of eccentricities and position errors. Obviously, a gear with a center contact is less affected by discrepant manufacturing or design; furthermore, you can reduce the backlash requirements and allow the gears to wear in rather than wear out.
