CONVERTER OF ROTATIONAL MOVEMENT TO TRANSLATIONAL MOVEMENT Russian patent published in 2013 - IPC F16H21/40 

FIELD: machine building.

SUBSTANCE: movement converter includes a housing, in which there coaxially installed are inlet and outlet shafts, a central gear wheel rigidly fixed on the housing coaxially to the inlet shaft. On the outlet shaft there installed are two similar elliptical gear wheels of one and the same size, which are turned relative to each other through 180°, and two identical satellites spaced at an angle of 180°. Each satellite consists of a cylindrical gear and an elliptical gear, which are connected to each other by means of the shaft, as well as a carrier fixed on the inlet shaft. A central fixed gear wheel is externally engaged with cylindrical gears of both satellites. Each elliptical gear wheel of the outlet shaft is engaged with one of elliptical gears of satellites. Elliptical gears of satellites and elliptical gear wheels of the outlet shaft are installed on their shafts so that shaft rotation axis passes through a point called a dividing ellipse focus of the elliptical gear wheel of the outlet shaft or elliptical gear of the satellite, which is located on large semi-axis of the dividing ellipse at distance c from the dividing ellipse centre.

EFFECT: increasing operational life and improving mechanism compactness.
