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

FIELD: machine engineering.

SUBSTANCE: invention relates to machine engineering and can be used in the non-reversing tooth-wheel gears operating with oil lubrication by immersion. A tooth-wheel contains a body, a tooth ring with teeth, each of them made as a half profile of the design tooth for this wheel, located on the lateral surface of the tooth involved in toothing, and a pair of circumferential butts mounted at the ends of the teeth and at the sections of the body ends adjacent to the tooth ring. The second half of each tooth profile is formed as a curved plate, the outer surface of which is identical to the second half of the profile, and the plate section forming a non-working section of the lateral surface is cut out to form a through window along the entire tooth width.

EFFECT: improving quality of the tooth-wheel lubrication is provided.
