GEAR WHEEL Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: gear wheel comprises a body, a ring gear, made of plates curved along the outer profile of the tooth, and a pair of circular pads. Each tooth is formed of a single plate. The width of the plate portion on the upwind side of the gear surface is less than the width of the gear rim; This plot is located at the center of the gear, at equal distances from the two circular pads across the gear height. Inside the cavity of the gear, along its height and perpendicular to the gear axis, there are flat rectangular shelves with width equal to the width of the gear, reinforced on the inner surface of the plate portion forming the lagging side surface and on the inner surfaces of the annular linings, with equal gaps relative to a plate forming run-on side surface. Parties shelves, facing the oncoming side surface are provided with visors width equal to the width of the gear facing towards the wheel body and executed relative equidistant upwind side surface, with equal gaps relatively downstream flanges and wheel body. The same visor, with the same gap, and fastened on the inner side of the plate portion forming the gear top.

EFFECT: improved quality of gear wheel lubrication.
