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

FIELD: machine building.

SUBSTANCE: invention relates to gear transmissions with wheels of internal engagement. Lubricating device of gearing comprises a pump connected with nozzle located above zone of engagement of paired transfer elements - pinion and gear wheel of internal engagement, which includes hub body made in form of disc, rim wheel and gear rim with teeth. Between hub of gear wheel and a circle projected on body of gear wheel by peak points of teeth of rotary pinion, with minimum clearance relative to said circle on body of gear wheel perpendicular to it and coaxially relative to axis of rotation of gear wheel there is fixed internal ring. At end of rim wheel, perpendicular to it, ring is installed with inner diameter equal to inner diameter of rim wheel. Between inner surfaces of a rim wheel and inner ring on surface of gear wheel body there is a pair of annular inserts. Between inserts in body surface of gear wheel there is an insert which is concentric relative to gear wheel, along circle of groove in its bottom in body of gear wheel there is a row of through holes provided at outlet with discharge nozzles.

EFFECT: higher quality of lubrication of gears.
