GEAR WHEEL Russian patent published in 2017 - IPC F16H55/17 F16H57/04 

FIELD: machine engineering.

SUBSTANCE: cylindrical gear wheel has a hub (1) protruding in one direction, a disk body (2), a rim (3) and a ring gear (4) with a width B greater than the thickness of the disc. At both ends of the wheel, a pair of annular linings (6) and (7) are reinforced, the planes of which are oriented in the plane of rotation of the wheel. Lining on its outer perimeter, whose diameter is smaller than the diameter of the circumference of the bases of the gear rim, are strengthened on the ends of the rim (3). From the end face of the wheel on which the end rim (3) and the end of the nave (1) are in the same plane, circular plate (6) on your inner perimeter is reinforced at the end of the hubs (1) and inner diameter of the lining more internal diameter of the hub. With another butt rims on which the hub (1) is made with the tab, inner diameter of second lining (7) is equal to the external diameter of the hub (1), and the lining on the outer surface of the district strengthened the hubs (1) through the ring, performed on internal perimetre of the lining, oriented in the direction of the disk (2) and adjacent to the surface.

EFFECT: invention improves the quality of the lubrication of gear.
