Oil nozzle for bearing chamber
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.
1 . A bearing chamber, comprising:
an interior surface comprising a terminal block defining a keyway and a conduit terminating at the keyway; 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.
2 . The bearing chamber according to claim 1 , wherein the interior surface and the terminal block are additively manufactured.
3 . The bearing chamber according to claim 1 , wherein the base comprises a fastening point at which the base is fastened to the terminal block at the keyway.
4 . The bearing chamber according to claim 1 , wherein the base sits flush against the recessed surface and an opening of the internal channel sits flush against a terminus of the conduit at the recessed surface.
5 . The bearing chamber according to claim 1 , wherein the oil nozzle comprises:
a main section defining the internal channel;
a main nozzle section coupled to the main section and defining a main nozzle internal channel communicative with the internal channel and an aperture at a distal end thereof; and
an additional nozzle section split off from the main nozzle section and defining an additional nozzle internal channel communicative with the main nozzle internal channel and an aperture at a distal end thereof.
6 . The bearing chamber according to claim 5 , wherein the main nozzle section and the additional nozzle section point in different directions.
7 . The bearing chamber according to claim 5 , wherein at least one of the main nozzle section and the additional nozzle section comprises grooves at the corresponding aperture.
8 . The bearing chamber according to claim 5 , wherein at least one of the main nozzle section and the additional nozzle section comprises rifling at the corresponding aperture.
9 . The bearing chamber according to claim 5 , wherein the main nozzle section and the additional nozzle section have different aperture configurations.
10 . The bearing chamber according to claim 5 , wherein a proximal end of the additional nozzle section comprises a turn.
11 . The bearing chamber according to claim 5 , further comprising another additional nozzle section which is split off from the main nozzle section.
12 . The bearing chamber according to claim 5 , further comprising another additional nozzle section which is split off from the additional nozzle section.
13 . The bearing chamber according to claim 1 , wherein the oil nozzle comprises:
a main section defining the internal channel;
a main nozzle section coupled to the main section and defining a main nozzle internal channel communicative with the internal channel and an aperture at a distal end thereof; and
multiple additional nozzle sections, each of which is split off from the main nozzle section and each of which defines an additional nozzle internal channel communicative with the main nozzle internal channel and an aperture at a distal end thereof.
14 . The bearing chamber according to claim 13 , wherein the main nozzle section and each of the multiple additional nozzle sections point in different directions.
15 . The bearing chamber according to claim 1 , wherein the oil nozzle comprises:
a main section defining the internal channel;
a main nozzle section coupled to the main section and defining a main nozzle internal channel communicative with the internal channel and an aperture at a distal end thereof through;
an additional nozzle section split off from the main nozzle section; and
another additional nozzle section split off from the additional nozzle section, each of the additional nozzle section and the another additional nozzle section defining an additional nozzle internal channel communicative with the main nozzle internal channel and an aperture at a distal end thereof.
16 . The bearing chamber according to claim 15 , wherein the main nozzle section, the additional nozzle section and the another additional nozzle section point in different directions.
17 . 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.
18 . The method according to claim 17 , wherein the establishing of the orientation of the keyway is set first and the configuration of the oil nozzle is based on the orientating of the keyway.
19 . The method according to claim 17 , wherein the establishing of the configuration of the oil nozzle is set first and the orientation of the keyway is based on the configuration of the oil nozzle.
