    Abstract: A low mass, two piece planetary gear carrier having an integrated clutch housing comprises a first carrier flange and clutch housing and a second carrier flange which are secured together by a plurality of threaded fasteners extending through hollow dowels. A plurality of planet gears receive needle bearing assemblies which are, in turn, supported on pins or stub shafts. The stub shafts are retained in the carrier by transverse retaining pins received in the second carrier flange and extending into the shafts. Unitized washers are disposed between both faces of the planet gears and the flanges. The method of assembly is also a feature of the present invention.

    Abstract translation: 具有集成离合器壳体的低质量两片式行星齿轮架包括第一承载法兰和离合器壳体以及第二承载法兰，该第二承载法兰通过延伸穿过中空榫钉的多个螺纹紧固件固定在一起。 多个行星齿轮接收滚针轴承组件，滚珠轴承组件又被支撑在销或短轴上。 短轴通过容纳在第二载体凸缘中并延伸到轴中的横向保持销保持在载体中。 单位垫圈设置在行星齿轮的两个面和法兰之间。 组装方法也是本发明的一个特征。

    Abstract: An additive manufacturing method includes providing a first composite material and forming a composite part matrix using the first composite material and defining a first layer, applying a first fiber reinforcing material to the composite part matrix atop and in contact with the first layer of the composite part matrix such that fibers of the first fiber reinforcing material are oriented in a first direction and form a second layer on the composite part matrix, applying a second fiber reinforcing material to the composite part matrix atop and in contact with the first fiber reinforcing material such that fibers of the second fiber reinforcing material are oriented in a second direction orthogonal to the first direction and form a third layer on the composite part matrix, applying the first composite material to the composite part matrix, and curing the composite part matrix to create a composite product.
