GEAR LUBRICATING DEVICE Russian patent published in 2016 - IPC F16H57/04 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in tooth gears with crankcase lubrication by dipping. Lubricating device contains oil bath with liquid lubricating material having upper level, located in gearing housing, and in which transmission gear wheel is immersed. At both ends of this wheel a pair of scrapers are rigidly fixed on gearing housing, fixed relative to rotating wheel and adjacent to ends of wheel over its entire length, scrapers are located above upper lubricant level bath. Lower ends of scrapers are located on vertical axis of symmetry of wheel, above lower points of circles described by points of contact surfaces of ends of wheel body with top level of lubricant bath, upper part of scrapers are brought to point of intersection of circumference of ring gear wheels with recesses bases projection of boundary of beginning of engagement zone and on vertical. Scrapers in their projections at ends of rims have form of arcs bent towards toothed rim. Top ends of scrapers are bent along horizontal line towards paired gear wheel and wheel rims is closed with covering Δ a projection of zone of engagement on horizontal plane.

EFFECT: higher quality of lubrication gear.
