Abstract
The invention relates to a structure (60) for an aircraft turbine engine, comprising a shaft (11) and a follower element (52) rotatably coupled to the shaft (11) by a spline connection (62), the structure comprising: - upstream and downstream connection pieces (68a, 68b) for radially centering the follower element (52) relative to the shaft (11); - means (36) for spraying lubricant into a collection cavity (74); - a channel (86) for receiving lubricant, which opens into the collection cavity (74) and into a cavity (66) for lubricating the spline, which is partially defined by the upstream and downstream radial centering connection pieces (68a, 68b); and - a channel (88) for discharging lubricant, which opens into the cavity (66) for lubricating the spline and to the outside of the structure.
