GEAR WHEEL Russian patent published in 2018 - IPC F16H55/12 

FIELD: engineering.

SUBSTANCE: invention relates to machine building and can be used in tooth gears. Gear wheel contains body in the form of disk and gear ring with teeth at the ends of which a pair of ring linings are reinforced. On the circumference of the body, in the bases of interdental slots, radially oriented cutouts are made along the whole width of the body, the lateral surfaces of each notch are interfaced with the lateral surfaces of the slots, the bottom of each cut is perpendicular to the ends of the body. In the body sections between adjacent cuts, through-going rectangular holes are made, oriented parallel to the ends of the body and perpendicular to the axes of symmetry of the slots under which they are made. Holes are arranged symmetrically with respect to the ends of the body, the top of each hole coincides in plan with the circumference of the bases of the gear rim, and the bottom of each hole is interfaced with the bottom of the adjacent notches.

EFFECT: construction is facilitated and the costs of manufacturing the gear are reduced.
