泵在小齿轮轮轴上的集成体
摘要：
本发明涉及一种航空器润滑装置(1)，该润滑装置包括具有小齿轮轮轴(22)的小齿轮(2)，小齿轮轮轴(22)是空心的且具有旋转轴线(R‑R′)，所述装置(1)的特征在于，它还包括：轴(23)，布置在小齿轮轮轴(22)的内部；空间(E)，位于轴(23)和小齿轮轮轴(22)之间，允许油到处运动；油贮藏器(31)，面对所述空间(E)地布置在小齿轮轮轴(22)的第一端部(22a)处；油排出管(42，421)，面对空间(E)地布置在小齿轮轮轴(22)的第二端部(22b)处，在所述装置中，小齿轮轮轴(22)和轴(23)以一起形成泵的方式布置，所述泵设计成由于小齿轮轮轴(22)关于轴(23)旋转，而将油从贮藏器(31)朝向油排出管(42，421)驱动。
摘要（英）：

A device lubricates elements of an accessory drive system of an aircraft. The device includes a pinion having a pinion shank that is hollow and that has an axis of rotation, a shaft arranged inside the pinion shank and extending along the axis of rotation, a space between the shaft and the pinion shank allowing displacement of oil, an oil reservoir arranged facing the space, at a first end of the pinion shank, and an oil outlet duct arranged facing the space, at a second end of the pinion shank. The pinion shank and the shaft together form a pump and cooperate to drive the oil from the reservoir toward the oil outlet duct thanks to the rotation of the pinion shank around the shaft.
