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 wheel rotation, in the zone of wheel engagement with the paired gear wheel of the transmission placed in closed housing. Teeth removed from engagement zone during wheel rotation are subjected to blowing by air flow in the form of separate jets from nozzles positioned on the side of the circumference of the teeth vertices of the gear rim, with a gap relative to it, along the width of the gear rim and oriented radially to the wheel. The air flow along the height of the teeth is optimised by means of the pair of ring linings fixed on the ends of teeth, in which through holes are made in areas of bases of gear rim recesses which are identical in profile and size to the bases of gear rim recesses and adjacent to along the circumference of gear bases rim and teeth side surfaces. The air used to create the air flow is taken from the gearbox housing.

EFFECT: improved quality of gear wheel lubrication.
