Abstract
A gear shroud arrangement includes a plate defining an aperture therethrough. A riser tube has a first end and an opposed second end. The first end of the riser tube is connected to the plate and is aligned with the aperture. A mounting flange extends from the second end of the riser tube. A shroud member extends from the plate in a direction opposite the riser tube.
Claims14
A gear shroud arrangement comprising:
- a plate defining an aperture therethrough;
- a riser tube having a first end and an opposed second end, wherein the first end of the riser tube is connected to the plate and is aligned with the aperture;
- a mounting flange extends from the second end of the riser tube;
- and
- a shroud member extending from the plate in a direction opposite the riser tube, wherein the shroud member includes:
- a first shroud segment circumferentially crossing a 12 o'clock position on the plate as viewed looking toward the mounting flange;
- a second shroud segment circumferentially between the 12 o'clock position and a 3 o'clock position relative to the 12 o'clock position;
- and
- a third shroud segment circumferentially between the 3 o'clock position and a 6 o'clock position relative to the 12 o'clock position, wherein the second and third shroud segments are convex relative to the riser tube, and wherein a concave web connects between the second and third shroud segments, wherein concave is relative to an axis parallel to the center axis of the riser tube and convex is relative to the axis parallel to the center axis of the riser tube.

- and
- a third shroud segment circumferentially between the 3 o'clock position and a 6 o'clock position relative to the 12 o'clock position;
- wherein the plate defines a registration feature for registering the plate with an integrated drive generator (IDG) housing, wherein the registration feature includes a radiused section extending from the 6 o'clock position to a 9 o'clock position relative to the 12 o'clock position;
- wherein the registration feature includes a first flat land extending tangent to the radiused section from the 9 o'clock position, terminating in an end that is perpendicular to the first flat land;
- wherein the registration feature includes a second flat land extending tangent to the radiused section from the 6 o'clock position, terminating at an end that is perpendicular to the second flat land.
