DRIVE Russian patent published in 2020 - IPC F16H19/02 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Drive consists of fixed cylindrical gear with inner ring gear rim, in which coaxially with fixed cylindrical wheel with toothed rim of internal engagement there is a carrier with two parasitic gears fixed on it, one of which is installed with possibility of rolling along internal gear rim of fixed cylindrical wheel, leading, at rotation of carrier, another gear engaged with central gear wheel with outer toothed rim installed in carrier eccentric orifice and rotating in the direction opposite to the carrier rotation direction. Number of cylindrical wheel teeth with inner toothed rim is twice more than number of teeth of central gear wheel with external gear rim, wherein on the central gear wheel with the external toothed rim there is an output roller, having holes in the base in the attachment points and having a gap between the fastening screws and holes in the base for movement along the central gear wheel with the outer gear rim and changing the distance between the axis of the output roller and the axis of the central gear wheel with the outer gear rim so that this distance is equal to the eccentricity of the hole in the carrier.

EFFECT: higher accuracy of rectilinear movement.
