FRICTION GEAR Russian patent published in 2015 - IPC F16N15/00 F16H13/00 

FIELD: machine building.

SUBSTANCE: cylindrical elements designed from hard material, the working surfaces of which are pressed to each other so, that the friction force originating at the contact, is equal to the value of transmitted circumferential force, they have deepenings filled with solid lubricant and located so that the trajectories, made by any point of perimeter of deepenings, are not intersected and are not superimposed in the zone of contact. The named deepenings can have the circular shape, shape of equilateral rectangle, one of diagonals of which coincides with generatrix of the cylindrical element, or the shape of rectangular quadrangle, one of sides of which coincides with generatrix of the cylindrical element. The deepenings can be located on generatrix of cylindrical elements, shaping the series at the pre-set distance from each other.

EFFECT: expansion of stable operation zone and increase of transmitted effort.
