FIELD: machine building.

SUBSTANCE: roller-screw reduction gear contains input link containing two nuts of input link with internal multistart thread of different direction, fixed relative to each other, support link comprising two support links with multistart thread of different direction, fixed relative to each other, output link contains two nuts of output link with multistart thread of different direction, fixed relative to each other. Outlet nuts have number of threads different from number of turns of nuts of support link, rollers having one pair of sections with thread of different direction. Multistart thread of support link nuts and output link nuts is made on their outer surface, rollers are located around two nuts of the support link and two nuts of the output link, so that each section of the roller from one pair of sections of rollers interacts with one of the nut of the support link and the nut of the output link, and two nuts of input link are located around rollers so that one pair of sections of rollers interacts with nuts of input link.

EFFECT: improved operational characteristics of the reduction gear.
