GEAR TRAIN Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: gear train contains conjugated twin gears, each consisting of a body and a gear rim with teeth. At the top of each tooth of each gear, along its width, with adjoining to the face between the vertex and the advancing side surface of the tooth and with the inscription in the theoretical extension of the calculated advancing side surface of the tooth, there is a row of teeth of pyramidal shape, which height is less than the value of the gear axial clearance. And the teeth of each second tooth of each wheel are displaced along the width of the tooth vertex by the value equal to half the tooth width.

EFFECT: improved reliability of the gear train.
