FIELD: machine building.
SUBSTANCE: invention relates to machine-building industry, in particular, to variable-speed gears. Variable-speed gear includes drive link - bell crank with piston-rod, outlet link - outlet shaft on which free-wheel clutches, two casings, a lever with slide and regulator are installed. Free-wheel clutches are installed inside each casing. Swinging motion of casings is converted by means of free-wheel clutches to continuous rotational motion of outlet shaft. Lever is a link in the circular slot of which a slide is installed. One end of lever is installed on fixed rotation axis, and the other end of lever is connected to piston-rod of drive link. Centre of slide is connected by means of two rods to two casings and by means of one rod to the regulator.
EFFECT: smooth adjustment of outlet shaft speed; enlarging the range of change of transmission ratios; higher reliability of the mechanism.
