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

FIELD: engines.

SUBSTANCE: invention relates to gear transmissions equipped with wheels of internal engagement. Lubricating device of gearing contains a pump connected with nozzle located above the zone of engagement of paired transfer elements, i.e. pinion and gear wheel of internal engagement, which includes hub body made in form of disc, rim wheel and gear rim with teeth. Between the hub gear wheel and a circle projected on body of the gear wheel by peak points of teeth of rotary pinion, with minimum clearance relative to the said circle on the body of gear wheel perpendicular to it and coaxially relative to axis of gear wheel rotation 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 the inner surfaces of rim wheel and inner ring in the gear wheel body surface there is a cut, concentric relative to the ring. Surfaces of cutout are inclined relative to each other. In the lower part of this cut along its circumference, in the gear wheel body there is a row of through holes provided outside the gear wheel with output nozzles.

EFFECT: higher quality of gear lubrication.
