Abstract
The planet wheel has either toothings having different diameters but a same tooth module or toothings of a same diameter but different tooth modules. The toothings are produced by die stamping of a disc down to a certain depth which provides, in the median plane of the disc, a central cheek against which bear the toothings thereby stiffening each tooth for preventing it from being crushed and deformed.
