Abstract

A gear assembly (100) for an aeronautical engine (10) is provided. The gear assembly (100) includes a first gear (102) disposed at a center line axis (12) of the gear assembly (100); a second gear (104) coupled to the first gear (102) in adjacent radial arrangement to form a first mesh (112) between the first gear (102) and the second gear (104); a static portion (108) coupled to the second gear (104) in adjacent circumferential arrangement, the static portion (108) defining a pocket (116); and a spray bar (110) disposed within the static portion (108) such that a supply opening (126) of the spray bar (110) is directed at the first mesh (112) between the first gear (102) and the second gear (104), wherein the supply opening (126) is configured to provide a flow of lubricant to the first mesh (112) between the first gear (102) and the second gear (104) and at least a portion of the flow of lubricant is collected by the pocket (116). The flow of lubricant is continuously released from the pocket (116) to a second mesh (114) between the second gear (104) and a third gear (106), or more generally to the gear system, to enable lubrication of the gears and bearings during an interruption condition.

Description

[0001] government funded research [0002] The project leading to this application has received funding from the Clean Sky 2 joint project under the European Union's Horizon 2020 research and innovation program under funding agreement number CS2-LPA-GAM-2018 / 2019-01. technical field [0003] The present subject matter relates generally to gear drive systems, or more specifically, to gear drive systems including gear assemblies having lubricant storage pockets. Background technique [0004] A gas turbine engine typically includes a fan and a core arranged in flow communication with each other. Furthermore, the core of a gas turbine engine typically includes a compressor section, a combustion section, a turbine section, and an exhaust section in a serial flow order. In operation, air is supplied from a fan to the inlet of the compressor section where one or more axial compressors progressively compress the air until it reaches the combustion section. Fuel is mixed with compr...
