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

FIELD: machine engineering.

SUBSTANCE: cog wheel contains the body, scalloped Crown with hollow teeth and a couple of ring pads, reinforced on the ends of the body and wheels. Outer diameter of lining diameter circumference is equal to the vertices of the ring gear, internal diameter less than the diameter of the circle overlap grounds the ring gear. Each tooth is made of a pair of rectangular plates with a width equal to the width of the ring gear, bent on the profile calculation for this wheel tooth, two lateral surfaces of the tooth. Plate strengthened between inner ring ends overlap. In a place of an adjunction of lateral running surface of the wheel to the body it implemented through holes. Inside the cavity of each tooth is an L-shaped element with a backlash regarding the plates forming resembling the side surface. One shelf element is perpendicular to the axis of the tooth and strengthened at the plate, forming lateral surface of left behind. The second shelf element is oriented toward the body and wheels with clearance for him. The first shelf element attached to the plate, forming lateral surface of left behind, with the gap relative to the circumference of the peaks ring gear. And the second Regiment of this element is located along its entire length with relative plate forming resembling a lateral surface, and equidistant to it.

EFFECT: improved quality of gear wheel lubrication.
