Abstract
A gearbox for a gas turbine engine may comprise a first gear housing. A second gear housing may be located proximate a first end of the first gear housing and may extend axially from the first gear housing. A third gear housing may be located proximate a second end of the first gear housing and may extend axially from the first gear housing. A fourth gear housing may extend circumferentially between second gear housing and the third gear housing.

A gearbox for a gas turbine engine, comprising:
- a first gear housing;
- a second gear housing located proximate a first end of the first gear housing and extending axially from the first gear housing;
- a third gear housing located proximate a second end of the first gear housing and extending axially from the first gear housing, wherein the first end of the first gear housing is opposite the second end of the first gear housing;
- and
- a fourth gear housing extending circumferentially between the second gear housing and the third gear housing, wherein the first gear housing is located at a first axial end of the third gear housing, and wherein the fourth gear housing is located at a second axial end of the third gear housing opposite the first axial end.

A gearbox for a gas turbine engine, comprising:
- a first gear train;
- a second gear train rotationally coupled to a first end of the first gear train;
- a third gear train rotationally coupled to a second end of the first gear train;
- and
- a fourth gear train rotationally coupled to the third gear train,
- wherein a first rotational axis of the first gear train, a second rotational axis of the second gear train, and a third rotational axis of the third gear train extend outwardly in mutually divergent directions such that the first rotational axis, the second rotational axis, and the third rotational axis are non-parallel to one another, and wherein the first gear train is located at a first axial end of the gearbox and the fourth gear train is located at a second axial end of the gearbox opposite the first axial end.
