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

FIELD: machine building.

SUBSTANCE: invention can be used to lubricate the helical wheels. Lubricating device of gearing, mainly helical wheel of high-speed stage of multi-stage gearing with crankcase lubrication, contains secondary lubricating pinion helical in passive engagement with lubricated tooth-wheel. Lubricant gear is arranged at the end of the lubricated tooth-wheel with lagging behind the output of its teeth of paired helical wheel gearing at end of the lubricating pinion, facing the opposite end of the lubricated tooth-wheel, coaxially to the axis of the lubricating pinion. Along the width of the toothed rim of the lubricated tooth-wheel fixed cylindrical barrel, the bottom of which is fixed on the axis of the lubricating pinion about said end of the gear wheel. Along the circumference of the shell, along generatrices of its cylinder, there are blades with length equal to that make the cylinder sleeve. Radius of circle circumscribed by blades is smaller than the distance from axis of the lubricating pinion to addendum circle of the lubricated tooth-wheel. Lower part of barrel with blades immersed in oil bath.

EFFECT: higher quality of lubrication.
