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

FIELD: machine building.

SUBSTANCE: invention 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 gear wheel is submerged. At both ends of this wheel 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 in 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 lubricating oil bath. Top ends of scrapers are brought to start zone of engagement conjugated gear teeth with overlapping of teeth apices of toothed rim. Scrapers in their projections at ends of rims have form of arcs, protruding side tops of toothed rim of this wheel.

EFFECT: higher quality of lubrication.
