METHOD FOR REMOVING MATERIAL OF CAVITY BETWEEN TEETH OF CYLINDRICAL ARCHED GEAR WHEEL Russian patent published in 2021 - IPC B23F9/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a method for manufacturing cylindrical arched gear wheels with circular teeth having an involute transverse profile. The method of removing the material of the space between the teeth of a cylindrical arched gear wheel includes cutting out an annular groove in the tooth space and removing the material from Zone Z₁ between the concave side surface of Tooth 1 and the side surface of the annular groove closest to it, as well as removing the material from Zone Z₂ between the other side surface of the annular groove and the convex side surface of adjacent Tooth 2. Material removal from both Zone Z₁ and Zone Z₂ is carried out by means of generating. As a result of performing each of the generating in Zone Z₁, a surface is formed that is equidistant to the concave lateral surface of Tooth 1, and in Zone Z₂ - a surface equidistant to the convex lateral surface of Tooth 2. Generating is performed using a cutter head. An annular groove in the tooth space is cut out by at least one annular drilling. Cutting in the hollow of the annular groove is carried out using a tool head or a crown drill.

EFFECT: unhindered exit of chippings from the cutting zone is provided and the load on the main drive of the machine and the cutting head is reduced.
