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

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in tooth gears. Gear wheel comprises hub, body in form of pair of disks fixed on hub ends, and gear rim composed of separate teeth, fixed by their ends between inner ends of disks. Each tooth is made of piece of strap with width along whole length, equal to width of toothed rim. Section of piece of strap with one end is bent in form of tooth, starting with main circle of toothed wheel to make its outer surface of tooth surfaces of identical design for given gear: working section of one side surface, tooth top working section of other side surface to main circle of toothed wheel. Remaining part of section of strip is bent, starting with main circle of toothed wheel, at its radius and adjoins hub, piece of strip along whole length, both by their ends fixed on inner ends of both discs. Volume between inner ends of disks and hub is filled with solidified melt, for example plastic, with maximum outer size not greater than radius of dedendum circle. Sections of outer surfaces of melt, located between adjacent sections of strips, immersed into melt, are made flat.

EFFECT: optimised gear wheel design.
