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

FIELD: mechanical engineering.

SUBSTANCE: gear includes a hub, body in the form of a disk, and a rim toothing, the width of which is greater than the thickness of the disc. At both ends of the wheel, with its output side by the rotation of the oil bath, above the upper level of the bath of lubricating material, a pair of flat L-shaped scrapers oriented radially relative to the wheel, with a slope towards the bath. The scrapers are still fastened relative to the rotating wheel, with adjacent to the inner surfaces of the rim and the surfaces of the end faces of the disc. The planes of the scrapers are perpendicular to this surfaces. The dimensions scraper sites, which are adjacent to the rim, are larger than the size of its ends. The distance from wheel center to the scraper sites, which are adjacent to the disc, is less than the radius of the circle described by the point of contact with the disc upper surface level of the lubricating material bath.

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