FIELD: mechanical engineering; drives at continuous control of gear ratio. SUBSTANCE: proposed device has one or more input disks and output disk which form one or more toroidal cavities . Several rollers are located in said toroidal cavities. Rollers are kept in contact with respective disks by application of end load pressure. One of disks is mounted on shaft by means of intermediate flexible member to ensure bending of shaft without deformation of toroidal cavity. EFFECT: enhanced efficiency and reliability. 17 cl, 6 dwg
