Epicyclic gear train speed reducer

Abstract

Speed ​​reducer (100) comprising at least one stage consisting of an epicyclic gear train, such that the rotation shafts (43…) at least of the satellites (42, 42' …) of the planet carrier plate (40) placed at the output of the reducer (100) are deformable, and undergo bending under the effect of the displacement of external support means (4) due to the weight of the load applied to them, said bending of the rotation shafts (43..) of the satellites (42, 42'…) of the output stage being capable of generating an axial component C2, parallel to the axis of rotation of the reducer (100), of the torque transmission force C exerted between each satellite (42, 42'…) of this stage and the ring gear (2) whose direction depends on the direction of rotation of the planet carrier plates (10, 20, 30, 40) of the reducer (100).
