GEAR WHEEL Russian patent published in 2017 - IPC F16H55/17 

FIELD: machine engineering.

SUBSTANCE: gear includes a hub, the body in the form of spokes, rim and ring gear. On the outer surface of the hub and the inner surface of the rim in the plane of rotation of each row of spokes, stiffeners are made, connecting the ends of adjacent spokes to each other. In the annular groove formed by the inner surface of the rim, the inner surfaces of the stiffeners and portions of the inner surfaces of the ends of the spokes located between these adjacent ribs and having the height of these ribs are provided with an annular insert having a U-shaped cross-section. The insert is installed in the mirror groove. The height of its sides equal to the height of ribs, the width of the insert is trough width, and its upper side is formed symmetrically convex.
