Abstract
A gear assembly includes a first gear having a first hub surrounded by a first plurality of teeth. The first plurality of teeth each define a respective first contact region. The gear assembly includes a second gear having a second hub surrounded by a second plurality of teeth. The second plurality of teeth are adapted to mesh with the first plurality of teeth at the respective first contact region in order to drive a respective load in a first direction. The first hub and the first plurality of teeth include respective zones defining a respective elastic modulus. A three-dimensional distribution of the respective physical size and the respective elastic modulus of the respective zones is optimized such that a fluctuation of mesh stiffness along the respective first contact region is at or below a first predefined threshold.
