Claims

Claims

1. Rotating part for an aircraft turbomachine, comprising a plurality of teeth (26) defining between them at least one groove (28), the radius of curvature of the bottom (30) of the at least one groove (28) being greater than or equal to the distance (D) between said bottom (30) and the axis (X) of the rotating part.

2. Rotating part according to claim 1, in which each tooth (26) has a head (32) bordered by two flanks (34).

3. Rotating part according to claim 2, in which the head (32) extends, from one flank (34) to the other, along an arc of a circle centered on the axis (X) of the rotating part.

4. A rotating part according to claim 2 or 3, wherein each flank (34) extends along an involute of a circle to the head (32).

5. A rotating part according to any one of claims 1 to 4, wherein the teeth (26) project towards the axis (X) of the rotating part.

6. A rotating part according to any one of claims 1 to 5, wherein the rotating part is a fan disc (14), a compressor shaft or a turbine shaft.

7. A rotating part according to any one of claims 1 to 6, wherein the teeth (26) extend, in the direction of the axis (X) of the rotating part, in a rectilinear, helical or curved manner.

8. Turbomachine (10) for aircraft, comprising a rotating part according to any one of claims 1 to 7.
