Abstract:
    The gear has moving toothed parts comprising uniformly distributed teeth with zones elastically deformable in a direction of its respective thickness. The sum of nominal thickness (eSJ, e2) of two teeth in contact with the respective moving parts, measured along pitch circles (C1, C2) of the parts, gives a resultant dimension greater than the pitch (p) of the parts. The thickness of the deformable zone extends on either side of theoretical profile of the teeth.
