GEAR WHEEL Russian patent published in 2017 - IPC F16H55/17 

FIELD: machine engineering.

SUBSTANCE: gear wheel comprises a body, a toothed crown hollow tines, made of plate, bent on the outer profile of the teeth to form in the incoming side surface of each tooth of the through hole in place of the surface of junction to the body of the wheel, and a pair of circular pads, mounted at the ends of teeth and the ends of the parts of the body adjacent to the ring gear. Wherein each tooth is formed of a single plate, a through hole is formed symmetrically with respect to a side surface equal to half the width of the opening width of the side surface of hole height is the sum of the height of the non-working portion of the side surface portion and the height of the side surface operating in the two-pair engagement mode. On the inner side surface of the upwind side reinforced pad, overlying the through hole along its width to form a gap between it and the wheel body.

EFFECT: improving the quality of the gear wheel lubrication.
