DEVICE FOR FEEDING OF LIQUID LUBRICANT TO GEAR UNITS Russian patent published in 2015 - IPC F16H57/04 F16N7/16 

FIELD: machine building.

SUBSTANCE: device for feeding of liquid lubricant to gear units comprises: an oil crankcase, implemented in the transmission housing; a bucket wheel, partially immersed in it and mounted on one of the transmission shafts; buckets fixed on its end and uniformly arranged along the wheel diameter, and also the oil storage vessel and the system of supply of lubricant to friction units. Each bucket is designed as enclosed vessel fitted with two internal transversal partitions, placed in the central part of its bottom surface and forming interconnecting cavities. Between partitions a drain hole is provisioned which is fitted with a final tube; opposite to it in the upper part of the vessel the hole for oil intake from crankcase is provisioned. The storage vessel for oil intake is designed as a chute with the central transversal partition fixed on the housing parallel to the wheel plane with a possibility of arranging of drain hole of the bucket, located in the upper position on the wheel above the chute. The system of supply of lubricant to friction surfaces is designed as distributive tubes embedded into the bottom of the chute.

EFFECT: greasing of several toothed gearings of reverse slow bucket wheel is ensured with simultaneous exception of inertial loads.
