GEAR TRANSMISSION Russian patent published in 2018 - IPC F16H55/08 F16H57/04 

FIELD: machine building.

SUBSTANCE: invention relates to mechanical engineering and can be used in gears lubricated with solid lubricants in powdery dispersed phase. Gear transmission comprises interfaced twin gears, each consisting of a body and a toothed crown with teeth. In the head of each tooth of each wheel, from the side of its top, along its width, a set of cuts is made, oriented parallel to the plane of rotation of the wheel, with the formation of equal-sized ridges between them, the cross sections of which have the form of equilateral trapezium, the small bases of which are located at the apex of the tooth. Sum of the uncut portions of the width of the tooth apex is equal to the quotient of the tooth width divided by the value of the gear engagement multiplicity. Depth of the notches does not exceed the height of the lateral tooth surfaces on the side of its vertex with a meshing, large one-pair. Bottom of the notches is located along an arc of a circle, coaxial to the wheel. Cutouts in the teeth of twin gears are made with the ability to interface uncut sections of their heads over the entire width of these sections.

EFFECT: providing higher quality of lubrication process of gear transmission.
