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

FIELD: machine building.

SUBSTANCE: invention can be used in tooth gears. Gear wheel comprises hub, body in form of a pair of discs fixed on hub ends, and a gear rim composed of separate unconnected teeth, fixed by their ends between the discs and truncated by their bases, both working areas of their side surfaces are left unchanged. Teeth are made of the section strips of width equal to the width of the gear rim, bent to the shape of teeth; the external surfaces of the teeth form the surfaces identical to those of the wheel teeth. Inner cavities of teeth along whole width of toothed rim are filled with inserts of hardened melt, for example plastic. Height of inserts is more than teeth height. Lower part of inserts in wheel rotation plane is pointed symmetrically relative to radial axes of symmetry of teeth.

EFFECT: optimised gear wheel design.
