Gears correction: y-type, k-type, tip relief and semi topping
novembre 29, 2022
The topic of gear correction is among the hottest topics in our work. We recently received a request for a project where breakage and noise issues were repeating over and over again. The idea from which we started together with our client is to recreate the situation of an ideal profile without distortions by generating regular contact. In reality, however, the problem is that the teeth deform under load, that is, by meshing with each other, they generate contrasting forces which lead to an increase or decrease in the pitch between the teeth of the same wheel.
Correction of the y-type profile
On the basis of the ideal profile, a correction is made to the tooth profile of the driven gear so that it is more recessed towards the inside of the same. This prevents noise and breakage making the mesh longer lasting. This correction can be made either by grinding or by modifying the tool.
K-type profile correction, tip relief and semi topping
The correction of the profile k takes place by straightening the curvature of the ideal and basic profile at the end, better defining the curvature of the room. Tip relief correction is applied specifically to pinions to prevent wear. As the name implies, it is a question of creating a relief of the head by adding a connection on the same. Finally, let's talk about the correction of the head chamfer or semi topping. The sharp edge of the side is eliminated.
