METHOD OF GEAR WHEEL LUBRICATION Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: method includes supply of lubricant to friction surfaces of teeth of its gear rim during rotating wheel operation, in the zone of wheel engagement with the paired gear wheel of the transmission placed in closed housing. The teeth removed from the engagement zone at wheel rotation are subjected to blowing with air flow from pair of nozzles installed at both ends of wheel, fixed relative to the rotating wheel, with gaps relative to them and oriented towards the bases of the gear rim recesses. Movement of air flows in gear rim recesses is optimized by setting pairs of annular plates on teeth ends, the inner diameter of plates is greater than the diameter of the gear rim base circumference. Air to form air flows is taken from inside of enclosed transmission housing.

EFFECT: improved quality of gear wheel lubrication.
