Abstract
A lubricated rotational connection system provided with a free-wheel having a driving part and a driven part as well as at least one rotational link member arranged in a linking space, the linking space being located radially between a driving linking section and a driven linking section. A lubrication device comprises a fluid circulation device constrained to rotate with a driven pumping section of the driven part. The fluid circulation device is set in rotation with respect to a driving pumping section when the driving speed of rotation of the driving pumping section is lower than the driven speed of rotation of the driven pumping section about the axis of rotation in order to generate a forced circulation of the lubricating fluid within the linking space.
