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

FIELD: machine building.

SUBSTANCE: lubricating device contains a lubricating element in form of a pinion made out of 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 identical pinion along the entire circle row of teeth is cut out with same pitch. Number of cut teeth per each pitch for each identical pinion is equal to number of other individual identical pinions. To ensure as minimum single pair engagement of the lubricating element the individual identical pinions are secured on axle with displacement of the individual identical pinions relatively to each other in plane of their rotation ensuring engagement with rotating lubricated wheel of at least one tooth of one of identical pinions. Body diameter of each individual identical pinion is reduced to minimum, and between the circle of this body and circle of teeth depressions of the design profile of the individual identical pinion there are radially oriented links between the body and teeth bases with cross-section identical to the projections of teeth bases on the body of the individual identical pinion.

EFFECT: higher efficiency of lubrication.
