Abstract
A bearing chamber is provided. The bearing chamber includes an interior surface comprising a terminal block defining a keyway and a conduit terminating at the keyway and an oil nozzle defining an internal channel. The oil nozzle includes a base tightly fittable in the keyway. When the base is tightly fit in the keyway, the internal channel is communicative with the conduit and an orientation of the keyway and a configuration of the oil nozzle are cooperatively established to aim the oil nozzle at a predefined target within the bearing chamber.
Claims19
A bearing chamber, comprising:
- an interior surface comprising a terminal block defining a keyway and a conduit terminating at the keyway;
- and
- an oil nozzle defining an internal channel and comprising a base fittable in the keyway,
- wherein, when the base is fit in the keyway:
- the internal channel is communicative with the conduit, and
- an orientation of the keyway and a configuration of the oil nozzle are cooperatively established to aim the oil nozzle at a predefined target within the bearing chamber,
- wherein:
- the terminal block has a surface from which the keyway is recessed and a recessed surface within the keyway at which the conduit terminates, and
- the keyway, the recessed surface and the base are each elongate with corresponding first, rounded ends and corresponding second, partially rounded and partially polygonal ends opposite the first, rounded ends.
A method of additively manufacturing a bearing chamber, the method comprising:
- additively manufacturing an interior surface comprising a terminal block defining a keyway and a conduit terminating at the keyway;
- forming an oil nozzle defining an internal channel and comprising a base;
- fitting the base in the keyway such that the internal channel is communicative with the conduit;
- and
- establishing an orientation of the keyway and a configuration of the oil nozzle to aim the oil nozzle at a predefined target within the bearing chamber,
- wherein:
- the terminal block has a surface from which the keyway is recessed and a recessed surface within the keyway at which the conduit terminates, and
- the keyway and the base are each elongate with corresponding first, rounded ends and corresponding second, partially rounded and partially polygonal ends opposite the first, rounded ends.
