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

FIELD: machine building.

SUBSTANCE: lubricating device of gearing contains a lubricating element in form of lubricating pinion and additional pinion, its teeth are made out of material with low friction coefficient, installed on axle of the lubricating pinion, and being in passive engagement with lubricated tooth-wheel. Teeth of the lubricating pinion are made with maximum width, and teeth of the additional pinion with minimum width. Both pinions are installed on the axle with possibility of independent rotation relatively to each other. In body of the lubricating pinion a cutout is made, in it tension spring is installed, it is secured on body of the lubricating pinion and body of the additional pinion ensuring the possibility of their forced rotation by this spring relatively to each other, and pressing of teeth of the lubricating pinion to the trailing side surfaces of teeth of the lubricated tooth-wheel, and pressing of teeth of additional pinion to the sagging side surfaces of teeth of lubricated tooth-wheel.

EFFECT: higher efficiency of lubrication.
