Scavenge system for gear assembly
A gear assembly including a first gear disposed at a centerline axis of the gear assembly; a second gear coupled to the first gear in adjacent radial arrangement; and a spraybar assembly disposed between a plurality of the second gear. The spraybar assembly defines an elongated neck extended between the plurality of second gear. A supply opening is defined through the elongated neck and the elongated neck defines a groove extended along a longitudinal direction.
1. A gear assembly, the gear assembly comprising:
a first gear disposed at a centerline axis of the gear assembly;
a second gear coupled to the first gear in adjacent radial arrangement;
a spraybar assembly disposed between a plurality of the second gear, wherein the spraybar assembly defines an elongated neck extended between the plurality of second gear, and wherein a supply opening is defined through the elongated neck, and wherein the elongated neck defines a groove extended along a longitudinal direction; and
a first lubricant collector disposed adjacent to the spraybar assembly, wherein the first lubricant collector is disposed around a first shaft,
wherein the first lubricant collector further defines a scavenge port extended substantially along a radial direction relative to the centerline axis.
2. The gear assembly of claim 1 , wherein the spraybar assembly defines the groove defining a curve directing a flow of lubricant along the longitudinal direction.
3. The gear assembly of claim 2 , wherein the spraybar assembly defines the groove defining the curve from a radially inward end proximate to the supply opening toward a radially outward end.
4. The gear assembly of claim 2 , wherein the spraybar assembly defines the groove adjacent to the supply opening defined through the elongated neck.
5. The gear assembly of claim 1 , wherein the groove is defined circumferentially adjacent to the second gear.
6. The gear assembly of claim 1 , wherein the first lubricant collector is disposed longitudinally adjacent to the groove of the spraybar assembly.
7. The gear assembly of claim 1 , wherein a scavenge opening is defined through the first lubricant collector adjacent to the groove of the spraybar assembly.
8. The gear assembly of claim 7 , wherein the spraybar assembly defines the groove extended along the longitudinal direction from a radially inward end toward a radially outward end adjacent to the scavenge opening defined through the first lubricant collector.
9. The gear assembly of claim 1 , wherein the first lubricant collector is defined substantially circumferentially relative to the centerline axis.
10. The gear assembly of claim 1 , wherein the first shaft is disposed substantially concentric to the centerline axis, wherein the first shaft is coupled to the first gear.
11. The gear assembly of claim 10 , wherein the first shaft is disposed through the first lubricant collector.
12. The gear assembly of claim 1 , wherein the first gear defines a sun gear rotatable around the centerline axis of the gear assembly, and wherein the second gear defines a planet gear meshed with the first gear.
13. The gear assembly of claim 1 , further comprising:
a third gear coupled to the second gear.
14. A mechanical or electro-mechanical system, the system comprising:
a gear assembly comprising:
a first gear disposed at a centerline axis of the gear assembly;
a second gear coupled to the first gear in adjacent radial arrangement;
a spraybar assembly disposed between a plurality of the second gear, wherein the spraybar assembly defines an elongated neck extended between the plurality of second gear, and wherein a supply opening is defined through the elongated neck, and wherein the elongated neck defines a groove extended along a longitudinal direction; and
a first lubricant collector disposed adjacent to the spraybar assembly, wherein the first lubricant collector is disposed around a first shaft,
wherein the first lubricant collector further defines a scavenge port extended substantially along a radial direction relative to the centerline axis.
15. The system of claim 14 , wherein the spraybar assembly defines the groove defining a curve directing a flow of lubricant along the longitudinal direction.
16. The system of claim 14 , wherein the spraybar assembly defines the groove extended along the longitudinal direction from a radially inward end toward a radially outward end adjacent to a scavenge opening defined through the first lubricant collector.
17. The system of claim 14 , wherein the first shaft is disposed substantially concentric to the centerline axis of the gear assembly, wherein the first shaft is coupled to the first gear of the gear assembly; and the system further comprises a third gear coupled to the second gear.
