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

FIELD: machine engineering.

SUBSTANCE: gear wheel comprises a body, a gear rim with hollow teeth made of plate, bent on the outer teeth profile to form through-holes in their impinging side surfaces in the place of the surfaces abutment to the wheel body, and a pair of circumferential linings fixed on the teeth ends and body portion ends adjacent to the gear rim. Inside each tooth with a clearance relative to its leading side surface and equidistant to it, a jumper bar is located mounted on the inner side of the tooth top and inner surfaces of circumferential lining to form a gap between it and the wheel body. Each tooth is formed of a single plate. In the tooth top in circumferential linings, through holes are made in the areas between the inside surface of the leading side surface and the jumper bar.

EFFECT: improved quality of gear wheel lubrication.
