Dynamic Analysis of High Contact Ratio Spur Gear Considering Surface Wear
Taking the high contact ratio spur gear as the research object.Surface wear of gear was calculated based on Archard wear model.Based on energy method,comprehensive mesh stiffness of gear pair was obtained,which was then expressed with seg-mentation function.The effect of surface wear to gear dynamics was studied under a single-degree-of-freedom gear dynamics model considering comprehensive mesh stiffness.Results show that tooth surface wear has a great influence on dynamic response of high contact ratio spur gear in light load condition,gear system has a complex changing process between quasi-period and chaos with the increase of wear.In heavy load condition,tooth surface wear has minimal effect on dynamic response,gear system keeps in periodic motion for a long time.
