FIELD: mechanical engineering. ^ SUBSTANCE: variator comprises housing (1), input shaft (2) with pins (8), output shaft, mechanism for changing gear ration that is provided with provided with handle (18) fit on the pins for permitting rotation in the plane of the axis of the input shaft by means of the handle and defines a single member, two cams (71) and (72), and three-shaft gear differential. The carrier of the differential is connected with the output shaft. The shafts of the differential wheels can rotate with a phase shift of 90° by means of the driving mechanisms. Each driving mechanism has rockers (101) and (102) that are in a contact with the different cams and connected with the shafts of the differential by means of the overrunning clutches. The planes of vibration of the rockers of different driving mechanisms are perpendicular and pass through the axis of the input shaft. ^ EFFECT: enhanced performance, simplified design, and reduced cost. ^ 9 dwg |
