Effects of Misalignments on Surface Wear of Spur Gearing
A surface wear prediction methodology for spur gears is proposed based on which the wear characteristics of the gear pair can be computed efficiently.The surface wear of an ideal spur gear pair is predicted and the influences of load levels and wear cycles are investigated to reveal a quantative relationship between wear and operating parameters.The misalignment of the gear pair is defined and counted into the quasi-static model to investigate its effects on gear wear.The results indicate that the introduction of misalignment may aggravate the load distribution status and accelerate the surface wear.To compensate the negative effects of misalignment,an involute crown modification strategy is proposed and its effectiveness on contact distribution improvement and wear deceleration are validated through wear depths predictions.
