GEARING (VERSIONS) Russian patent published in 2013 - IPC F16H1/08 F16H55/08 

FIELD: machine building.

SUBSTANCE: gearing consists of two spurs 1, 2 with parallel rotational axes. Teeth composed of asymmetric segments are arranged in pairs in planes perpendicular to rotational axes of spurs. Both spurs have even number of teeth each of which having conjugated working profiles arranged at one angular pitch of one direction. The number of first spur teeth equals that of second spur is selected in compliance with definite relationship. In compliance with second version, gearing has several equally-shifted teeth at second spur in the plane of first spur tooth, their number being related by definite relationship.

EFFECT: reversing gearing with positive gear ratio, decreased overall dimensions.
