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 lubricated by plastic lubricants. Gear wheel includes a body, a gear rim with teeth and a pair of end butts with external diameters equal to diameter of the addendum circle, and with inside diameter smaller than diameter of the circle of the teeth bases. Adjustment are made of different thickness in radial plane of the wheel, and have maximum depth in the area of tooth tips and minimum - at tooth root fillets. Thickness taper is one-stage. Butts are secured on the teeth ends and sections of the ends of the body adjacent to the rim. Each butt is composite, consisting of two separate concentric circular butts. Circular butts are different from each other by value of said thickness and adjoin each other along a border of changing their mutual thickness. Butt of less thickness along its outer perimeter is fixed also on the inner perimeter of the second butt, for this purpose it is equipped with annular projection located perpendicular to its outer end.

EFFECT: saving material when making gear wheel.
