Oil scraper

A gear assembly, comprising:

• a first gear that rotates about a first axis and includes a first gear face with a plurality of first gear teeth, each of the plurality of first gear teeth having a radially outer surface forming a portion of the first gear face;
• a second gear that rotates about a second axis and includes a second gear face with a plurality of second gear teeth, where the first axis is not parallel with the second axis and the first and second teeth rotatably engage as the first gear rotates about the first axis and the second gear rotates about the second axis;
• and
• a shroud coaxially located over the plurality of first teeth, where the shroud includes a base surface and a circumferential sidewall extending from the base surface and a first cutout in the sidewall for the first gear teeth and the second gear teeth to rotatably engage and a second cutout in the sidewall with a radially inward extending interference surface in face-to-face proximity with the radially outer surface of at least of a portion of the plurality of first gear teeth, where the radially inward extending interference surface removes oil entrained adjacent to the plurality of first gear teeth as the first gear rotates, and where the radially inward extending interference surface causes a disruption to air pressure about the rotating first plurality of teeth to disrupt forces entraining oil with respect to the first plurality of teeth to reduce the amount of entrained oil.

A gas turbine engine gear assembly, comprising:

• a first gear that rotates about a first axis and includes a first gear face with a plurality of first gear teeth, each of the plurality of first gear teeth having a radially outer surface forming a portion of the first gear face;
• a second gear that rotates about a second axis and includes a second gear face with a plurality of second gear teeth, where the first axis is not parallel with the second axis and the first and second teeth rotatably engage as the first gear rotates about the first axis and the second gear rotates about the second axis;
• a shroud coaxially located over the plurality of first teeth, where the shroud includes a base surface and a circumferential sidewall extending from the base surface, a first cutout in the sidewall for the first gear teeth and the second gear teeth to rotatably engage, and a second cutout in the sidewall with a radially inward extending interference surface in face-to-face non-contacting proximity with the radially outer surface of at least of a portion of the first plurality of teeth, where the radially inward extending interference surface removes oil entrained adjacent to the plurality of first gear teeth as the first gear rotates, and the shroud and radially inward extending interference surface are of unitary construction, and where the radially inward extending interference surface causes a disruption to air pressure about the rotating first plurality of teeth to disrupt forces entraining oil with respect to the first plurality of teeth to reduce the amount of entrained oil.
