This gearbox to be assembled to a turbomachine portion and driven by a power take-off radial shaft thereof, includes several branches, the essential advantage of which is to allow a great amount of pieces of equipment to be driven to be accommodated, without implying a significant overall size in any dimension, since the gearbox remains close to the turbomachine and the pieces of equipment can be distributed on a large surface area. The housing (5) is divided into portions (27, 28) assembled to each other at the bends, in order to reduce its manufacturing cost.

1. A gearbox to be attached to a turbomachine (4) for driving at least one piece of equipment (10) related to the turbomachine, comprising a housing (13), a drive chain (14) internal to the housing, as well as a power take-off member for meshing with a transmission shaft of the turbomachine, the hou
1. A gearbox to be attached to a turbomachine (4) for driving at least one piece of equipment (10) related to the turbomachine, comprising a housing (13), a drive chain (14) internal to the housing, as well as a power take-off member for meshing with a transmission shaft of the turbomachine, the housing comprising attachment points (12) to the turbomachine and the piece of equipment, characterized in that the drive chain consists of a plurality of successive gear lines and forming angles to each other, the housing (13) comprises at least two consecutive portions, assembled to at least one junction interface, forming an angle to each other and each containing one of the gear lines (15, 16, 17), and said portions (27, 28; 45, 46) are distinct and assembled to each other at the junction interface. 2. The gearbox according to claim 1, characterized in that the junction interface of the housing portions is oblique to the branches. 3. The gearbox according to claim 2, characterized in that the junction interface of the housing portions is at a diagonal of a bend of the housing. 4. The gearbox according to claim 1, characterized in that the junction interface of the housing portions is parallel to a main face of one of said housing portions. 5. The gearbox according to claim 4, characterized in that the junction interface of the housing portions belongs to said main face. 6. The gearbox according to claim 1, characterized in that the drive chain comprises a gear having a meshing junction (47) which coincides with the junction interface (30) of the housing portions. 7. The gearbox according to claim 6, characterized in that said gear is the junction gear of both gear lines. 8. The gearbox according to claim 7, characterized in that the junction interface of the housing portions is oblique to the branches and the junction gear of both gear lines consists of bevel wheels. 9. The gearbox according to claim 6, characterized in that the junction interface of the housing portions is parallel to a main face of one of said housing portions and said gear consists of spur wheels (18a, 18b). 10. The gearbox according to claim 1, characterized in that the consecutive housing portions comprise at least one rectilinear branch (1, 2) and a partly circular branch (3) assembled to the rectilinear branch, the gear lines (15, 16, 17) each consisting of toothed wheels having axes of rotation all perpendicular to a same plane.
