DRIVE GEARBOX ON A TURBOMACHINE, CONSISTING OF A DRIVE TRAIN WITH GEAR LINES EXTENDING INTO NON-PARALLEL PLANES

摘要

The invention relates to a gearbox to be mounted on a turbomachine (4) and driven by a radial drive shaft thereof, said gearbox being characterised by a three-dimensional or sinuous shape, the fundamental advantage thereof being the capacity to house a large amount of equipment to be driven, without occupying a large amount of space in any dimension, since the gearbox remains close to the turbomachine and the equipment (10) can be distributed over a large surface. The drive train of gears extends successively into a plurality of non-parallel planes and comprises an axial branch on the turbomachine and a branch forming an arc of circle around the turbomachine.
