Patent ID: 8876647

Claim:
A reduction gear with epicycloidal gear train equipped with an oil feed device, said reduction gear comprising: a sun pinion that can move in rotation about a common axis of rotation, and planet pinions borne by a planet carrier, the planet pinions being driven by said sun pinion and being able to move in rotation about planet axes, said planet pinions rolling on a fixed ring gear, said device comprising: an oil tank, at least one fixed oil supply duct, oil routing ducts, said routing ducts also being able to move in rotation about the common axis of rotation, an oil ejection device at an end of the fixed supply duct, the orientation of which includes a radial component directed away from the common axis of rotation, and a cylindrical recovery device for recovering the oil, the recovery device moving in rotation about said common axis of rotation and positioned facing said ejection device, wherein said oil ejection device is linked by at least one duct to a lubrication device for the gear formed by the cooperation of the teeth of at least one planet pinion with an adjacent pinion.
