Abstract
Methods and apparatuses are described to increase emissivity within a gearbox. Loss-of-lube conditions can cause a gearbox in a vehicle to quickly heat up and fail, which could lead to loss of aircraft and/or life. Surface treatments within a gearbox, such as black paint, black oxide coatings, shot-peening, and others, can increase emissivity within the gearbox. The increased emissivity can increase heat transfer via radiation, leading to longer operational capabilities during loss-of-lube conditions.
Claims11
A method of increasing emissivity in a gearbox, the gearbox comprising a housing, the method comprising:
- applying one or more surface treatments to an inner facing surface of the housing, the one or more surface treatments configured to increase the emissivity, wherein the applying is performed after the gearbox is at least partially assembled.
A method of increasing emissivity in a gearbox, comprising:
- disassembling at least a portion of the gearbox to access one or more components of the gearbox;
- applying one or more surface treatments to one or more surfaces of the one or more components, the one or more surface treatments configured to increase the emissivity within the gearbox;
- and
- assembling the one or more components into the gearbox.
