GEAR WHEEL Russian patent published in 2018 - IPC F16H55/12 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering and can be used in gears lubricated with liquid lubricants by immersion. Gear wheel comprises a hub, a ring gear rim and a disc-shaped body having a thickness smaller than width of rim. At the body and the rim inner surface end faces, a pair of rings are secured, which outer diameter is equal to the rim inner diameter, their thickness is equal to the distance from the body end face to the rim end face, and the rings inner surfaces are made inclined away from the of the body end faces to the rim end faces. Each ring cross section has the form of a rectangular trapezoid, which right angle coincides with the angle between the body end face and the rim inner surface.

EFFECT: optimized gear wheel design.
