FIELD: machine building.

SUBSTANCE: invention can be used in low-loaded tooth gears. Gear wheel comprises hub body and toothed rim, made in form of profiled ring from strap with width equal to width of teeth, external profile corresponds to design profile of toothed rim gear wheel. Ring by one end face is secured on body end. Body is made in form of a flat ring connected with hub spokes, outer diameter of flat ring is equal to diameter of circle of tips of toothed rim, and inner diameter of flat ring is equal to inner diameter of profile ring. Spokes are located on side of same end of flat ring as shaped ring. They are fixed on end of flat ring between projections of profiled ring forming teeth side surfaces of toothed rim along axis of symmetry into sections from inner circle of flat ring to vertices of teeth with abutment to vertices and attachment to it.
