A gear includes a first gear rim, a second gear rim, and an axial groove. The first gear rim has a first gear rim rotational stiffness and includes a plurality of first gear teeth. The second gear rim has a second gear rim rotational stiffness. The second gear rim includes a plurality of second gear teeth complementing the plurality of first gear teeth defining a plurality of complementary first gear teeth and a plurality of complementary second gear teeth. The axial groove extends between the first gear rim and the second gear rim. The axial groove has an axial groove rotational stiffness that less than at least one of the first gear rim rotational stiffness and the second gear rim rotational stiffness.
