Abstract
A gas turbine engine with a lubrication system includes a ball bearing assembly and a rotor circumscribing a rotational axis and journaled within the ball bearing assembly. The gas turbine engine also includes a lubrication system located radially outward from a rotational axis and radially outward and adjacent to the ball bearing assembly, which includes a lubrication channel having an inlet and an outlet and a dispersion cone adjacent to the outlet of the lubrication channel.
Claims11
A gas turbine engine, comprising:
- a bearing assembly;
- a rotor rotatable about a rotational axis, the rotor journaled within the bearing assembly;
- and
- a lubrication system arranged radially outward of and in fluid communication with the bearing assembly, the lubrication system comprising:
- a lubrication channel including an inlet and an outlet;
- and
- a dispersion cone configured to receive lubricant from the outlet, the dispersion cone comprising a spar within an interior of the dispersion cone, the spar formed integral with the dispersion cone, the spar configured to disperse the lubricant traveling through the dispersion cone, the spar extending between a leading edge and a trailing edge, the leading edge having a blunt profile, and the trailing edge having a sharp profile.
