GEAR WHEEL Russian patent published in 2014 - IPC F16H55/08 F16H55/17 

FIELD: machine building.

SUBSTANCE: invention refers to machine building, namely to machine parts, and can be used in irreversible tooth gears. A gear wheel includes a body and a gear rim with teeth having working side face and non-working side face. Profile of the working side face of each tooth is identical to the design one for the tooth of the gear wheel, and profile of the non-working side face is made in the form of a plane passing along the symmetry axis of the design tooth, a ridge with the profile identical to the profile of the working side face is set in the centre of this plane. A ridge in the form of a right-angled triangle is placed in the area of each tooth end in this plane, one side of the triangle is set along the symmetry axis of the design tooth and the hypotenuse connects the midpoint of the apex of this tooth with its base.

EFFECT: lower material consumption at gear wheel manufacturing, its optimised design.
