The gearbox (10) has longitudinal parallel primary (12) and secondary (14) shafts each rotating in end bearings (24,26,30,32). These bearings are carried by front (18) and rear (20) parts of a casing (16). Each shaft is rotationally guided by a third central bearing (34,36) carried by first (38) and second (40) half walls integral with the rear part (20) of the gearbox casing.
