| 摘要 |
The invention relates to a speed reducer comprising two intermediate transmission lines (4,5), in particular for a turbomachine, comprising an input line (2) and an output line (3) driven by the input line by means of said intermediate lines, said intermediate lines being substantially parallel to an axis of rotation (B) of the input line (2), said reducer further comprising means for distributing loads between the intermediate lines (4, 5), characterised in that said distributing means comprise a pinion (7) rigidly attached to a shaft (6) of the input line, the input line being movable in translation along said axis (B) and comprising two external helical toothed rings (7a, 7b), the helices of which are orientated in opposite directions, each engaging respectively with a pinion (12, 13) of an intermediate line (4, 5). The invention also relates to a turbomachine comprising such a speed reducer and a method for distributing loads in such a reducer. |
