Failure Analysis of Sun Gear Splines in Fan Gearboxes by Ren Yanyan, Wang Yaqiang

“…The failure of sun gear splines is mainly caused by low tooth surface hardness. At the same time, due to the comprehensive action of fatigue wear, chemical corrosion, abrasive wear and other wear mechanisms, serious tooth surface wear occurs, resulting in a decrease of the bearing capacity of IMS sun gear motor side splines. …”

Improved Genetic Algorithm of Helical Gear Reducer and 3D Modeling by Hao Liping

“…Based on the penalty function method combined with the improved genetic algorithm,the multi-objective and multi-restriction reliability optimal design of the reducer with hardened tooth surface and modified helical cylinder gear is carried out.According to the properties of the constraint conditions,the different methods are used for effectively avoiding the local optimum problem.The accurate three-dimensional description of the involute gear is carried out by the establishment of the tooth profile curve coordinate equation of the involute gear.According to the interface technology of VB and SolidWorks,the three-dimensional parametric modeling of the involute gear is achieved based on the optimal design results.…”
