FIELD: machine building.

SUBSTANCE: invention can be used in tooth gears. Gear wheel includes body, gear rim with teeth and pair of ring pads fixed on teeth ends and sections of ends of body adjacent to gear rim width of teeth on sections of their heads and feet is gradually varying and inversely proportional to independent of engagement pairing. Boundaries of change of width of teeth are displaced in side of tops and bases of teeth on half value of axial clearance transmission.
