A reduction gear including an input shaft including an input gear, an output shaft including an output gear, and two intermediate transmission lines, each intermediate transmission line including an intermediate shaft including a first stage of teeth and a second stage of teeth, the stages rotating as one, and an additional gear for meshing respectively with the first stage of teeth and the input gear, or with the second stage of teeth and the output gear, and the reduction gear wherein the input gear or the output gear meshing with the additional gears is axially offset with respect to the stage of teeth of the intermediate shafts meshing with the additional gears.

Reduction gear with input/output rotation reversal

Speed reduction gear comprising two intermediate transmission lines, in particular for a turbine engine, comprising an input line () and an output line that is driven by the input line via said intermediate transmission lines, said intermediate transmission lines being substantially parallel, characterized in that said reduction gear comprises means for distributing loads between said intermediate lines, said load distribution means comprising swiveling coupling means () for rotatably coupling one end of the input line, and oil-damping means () for damping radial movements of an opposite end of the input line.
