LUBRICATING DEVICE OF GEAR TRANSMISSION Russian patent published in 2015 - IPC F16H57/04 

FIELD: machine building.

SUBSTANCE: lubricating device of gear transmission contains lubricating element in form of pinion secured on axle immersed in oil bath and engaged with above located lubricated wheel of high-speed stage gear. The pinion is made composite, comprising several individual identical pinions rigidly secured on same axle and distributed along the toothed rim of the wheel. From the toothed rim of each individual pinion along the entire circle row of teeth is cut out with same pitch. Number of cut teeth per each pitch for each individual pinion is equal to number of other individual pinions. To ensure as minimum single pair engagement of the lubricating element the individual pinions are secured on axle with displacement of the individual pinions relatively to each other in plane of their rotation ensuring engagement with rotating wheel of at least one tooth of one of individual pinions.

EFFECT: higher efficiency of lubrication.
