A rotating cutting tool to cut asymmetrical teeth in a gearwheel in which each tooth (21) has an active flank (A) with a convex profile meshing with the profile of a tooth of an opposing gearwheel meshing with the gearwheel and a secondary concave flank (S), provided with teeth (11) on a generally helical path which extends from one side to the other with respect to a median cross-section (M-M) of the tool which is intended to be intersected by the radius Rp of the gearwheel which is at right angles to the axis of rotation of the tool working on the gearwheel to cut its teeth. The helical teeth have a first flank (CA) which is intended to cut the said active flank (A) of the gearwheel teeth and a second flank (CS) intended to cut the secondary flank (S), the pitch (P1) between the first flank (CA) of the helical teeth being constant and the pitch (P2) of the second flank of the teeth being smaller than the pitch (P1).
A Rotary cutting tool for generating asymmetrical teeth in a gear wheel wherein each tooth has an active side (A) with convex profile conjugated with the profile of a tooth of a counter gear wheel meshing with the gear wheel and a secondary concave side (S), wherein it is provided with a toothing having a generally helical development, which extends on one side and the other side with respect to a median section (M-M) of the tool intended to be intersected by the radius Rp of the wheel, said radius Rp being orthogonal to the rotation axis of the tool operating on the wheel to generate the teeth thereof, the helical toothing having a first side (CA) defining a cutting edge intended to generate said active side (A) of the wheel teeth and a second side (CS) defining a cutting edge intended to generate the secondary side (S), the pitch (P1) between the cutting edge of the first side (CA) of the helical toothing being constant and the pitch (P2) between the cutting edge of the second side of the toothing being greater than the pitch (P1) and variable along the axial direction of the tool.
