GEAR TRANSMISSION Russian patent published in 2018 - IPC 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. At the top of each tooth of each wheel, along its width, with an abutment to each face between the top and both lateral surfaces of the tooth and with a fit in the theoretical continuations of the calculated lateral surfaces of the tooth, a row of pyramidal teeth is located, whose height is less than the axial clearance of the transmission. And the teeth of both rows are offset relative to one another in the plan of the tip along its width by half the distance between the tips of these teeth.

EFFECT: ensuring high reliability of operation of the gear transmission.
