  • Publication number: 20140260790
    Abstract: A unitary and integrally formed ring gear shroud having a first end portion, an arc-shaped middle portion, a second end portion, a first side and a second side. The first end portion extends orthogonally from the arc-shaped middle portion. The second end portion extends orthogonally from the arc-shaped middle portion, opposite the first end portion. The first end portion and the second end portions each extend from the arc-shaped middle portion. The first and second sides each have an inner surface and an outer surface. The inner and outer surfaces of the first side define a first radiused opening. The inner and outer surfaces of the second side also define a second radiused opening, wherein the first opening has a larger radius than the second opening. The outer surfaces of the first side and the second side are non-symmetrical.
