GEAR WHEEL Russian patent published in 2016 - IPC F16H55/12 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to machine parts, and can be used in tooth gears with coarse-grained large-diameter gear wheels with impact loading mode of teeth of different amplitude along circumferences of wheels. Gear wheel includes a body, a gear rim with teeth and a pair of flat ring pads fixed on teeth ends. Sections of ring pads between adjacent pairs of teeth are made with an arched shape, bent in plane of rotation of gear wheel in direction from its centre, and values of curvature radii of said sections of ring pads are directly proportional to values of amplitudes of impact loading of teeth.

EFFECT: providing damping of impact loads acting on wheel teeth of large diameter.
