摘要： A composite ring gear (10) with a metallic gear insert (30) has at least one filament (34) wound about the gear insert and an eyelet (32) a plurality of times. The filament is adapted to withstand a portion of a tensile load transmitted between the insert and the eyelet. The insert, eyelet and filament are then embedded in a composite material.

摘要： A composite gear and method of making same. In one embodiment the gear includes a body portion having a plurality of teeth. The gear is formed by placing it in a suitable tool such that a compressive stress is exerted on the teeth adjacent the root portion of each tooth. A portion of the gear adjacent the teeth is wrapped with a resin fibrous material that is allowed to cure while the compressive stress is maintained on the gear. When the resin fibrous material has at least substantially cured and the gear is removed from the tool, a permanent compressive stress is formed at the root portion adjacent each tooth. The compressive stress counteracts the tension stress that is experienced at the root portions of the teeth when the gear is in use, thus significantly strengthening (i.e., toughening) the gear and increasing its fatigue life.
摘要翻译：复合齿轮及其制造方法。在一个实施例中，齿轮包括具有多个齿的主体部分。齿轮通过将其放置在合适的工具中而形成，使得压缩应力施加在与每个齿的根部附近的齿上。邻近齿的齿轮的一部分用树脂纤维材料包裹，该树脂纤维材料在压缩应力保持在齿轮上时允许固化。当树脂纤维材料至少基本上固化并且齿轮从工具中移除时，在与每个齿相邻的根部处形成永久的压缩应力。压缩应力抵消当齿轮使用时在齿的根部处经历的拉伸应力，从而显着地增强（即增韧）齿轮并增加其疲劳寿命。

摘要： A light weight, split torque, geared power transmission having a reduced number of gears and useful for, e.g., transmitting power from an engine to the main rotor of a rotorcraft, includes a ring gear having a pair of oppositely facing angular bevel gears respectively formed on opposite sides of a medial plane thereof, and a first pinion having an elongated drive shaft extending through the medial plane of the ring gear and disposed at an oblique angle relative thereto. The first pinion includes a pair of cylindrical gears mounted coaxially on the drive shaft and respectively disposed in conjugate meshing engagement with respective ones of the bevel gears of the ring gear. An elongated annular output shaft made of a strong, light weight composite material is coupled to a circumferential periphery of the ring gear.
