FIELD: machine building. ^ SUBSTANCE: invention refers to the sphere of machine building and may be utilised for design of transmission gears of tractive, transportation and other machinery as well as machine tool drives and other mechanisms to provide for smooth regulation of speed, speed reversal and brakeage of their actuator devices, the device described being capable of functioning as a master clutch, a gearbox, a reduction gear, a reverse box, a steering clutch or a brake. With the proposed planetary variator the central wheels (1, 2) are represented by hollow cone frusta whose outer and inner surfaces simultaneously contact the satellites (3) via a tooth-and-plate or toothed and tooth-and-plate gearing. ^ EFFECT: variator load capacity increase. ^ 2 cl, 4 dwg |
