GEAR LUBRICATING DEVICE Russian patent published in 2018 - IPC F16H57/04 

FIELD: engineering.

SUBSTANCE: invention relates to machine building and may be used in tooth gears. Lubricating device comprises an oil bath with a liquid lubricant into which the lower gear wheel of the gear is submerged, in a kinematic relationship with the other transmission gears. Lower gear consists of a disc-shaped body with a hub and a rim with a ring gear. Rim width is greater than the thickness of the body disc. From each end of the lower gear, from which the outer edge of the rim with the ring gear extends beyond the body disk envelope, on the vertical axis of symmetry of the end of the wheel, a rectangular shaped scraper is mounted radially to the wheel above the hub, fixed on a base fixed to the rotating wheel. Scraper adjoins two of its ribs to the inner surface of the rim and to the surface of the end face of the body disc adjoining the rim. Width of the scraper is not less than the distance from the end of the disc to the end of the rim, the height of the scraper is not less than the depth of immersion of the disc in the oil bath with liquid lubricant. Under the scraper there is mounted an oil receiving tank fixed to the stationary wheel relative to the rotating wheel, equipped with an oil-extracting tray fed to the friction zones of the transmission elements, which need lubrication with a liquid lubricant.

EFFECT: providing higher quality of the gear lubrication.
