PULSE VARIATOR Russian patent published in 2011 - IPC F16H29/04 

FIELD: machine building.

SUBSTANCE: invention refers to machine building, particularly, to pulse variators. The pulse variator consists of a case, of a driving shaft, of a driven shaft, of a swash plate equipped with an internal bushing and a bearing installed in an intermediate ring. With its axes the intermediate ring is connected with an external ring equipped with journals. Relative to journals the said axes are arranged at an angle equal to a double value of angle of a dividing cone of transfer members in form of conic gears mounted on the said journals by means of a free-wheel clutch mechanism. The conic gears engage the conic wheel rigidly coupled with the driven shaft. Also, the mechanism of change of swash plate angle is equipped with two tooth sectors engaging two cylinder gears. Rack bars facilitate kinematic link between the cylinder gears and the internal sleeve of the bearing of the mechanism changing angle of incline of the swash plate.

EFFECT: expanded range of control of gear ratio, improved weight-dimension characteristics of variator, reduced non-uniformity of output shaft rotation.
