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

FIELD: machine engineering.

SUBSTANCE: gear wheel has a hub, a gear rim, a rim and a body in the form of disc, which thickness is less than width of the rim. A pair of rings is fixed on the body ends and the inner surface of the rim, which outer diameter which equals the inner diameter of the rim, their thickness equals the distance from the body end the end face of the rim, the inner surfaces of the rings are inclined towards the body sides towards the ends of the rim. Each ring cross-section is in the form of a rectangular trapezoid, which right angle coincides with the angle between the body end and the inner surface of the rim. The rings are hollow.

EFFECT: optimised gear design.
