METHOD OF GEAR WHEEL MANUFACTURING Russian patent published in 2014 - IPC F16H55/12 

FIELD: machine building.

SUBSTANCE: method of gear wheel manufacturing involves separate production of a body (1) and a rim wheel consisting of a rim (2) fitted by a geared rim with teeth (3) set on it, and their further assembly. The body (1) is made as a cylindrical disk with the diameter less than the diameter of the inner surface of the rim (2). The rim is fitted by splines (4) set on its inner surface by the symmetry planes of the geared rim's teeth (3) perpendicular to the rim end faces (7). The height of the splines (4) is more than the difference of radiuses of the inner rim surface and the peripheral body surface. The body periphery is fitted by grooves (10) mating the rim splines and having the section exceeding the splines' sections. The rim wheel and the body are matched coaxially with each other with their end faces being set in one plane and are fixed in this position. The cavities between the body and the rim are filled by melted material, for example, plastic, the melt is matured until hardening, afterwards fixing elements are removed from the gear wheel.

EFFECT: simplified process of gear wheel manufacturing and its improved reliability.
