DYNAMIC VARIATOR Russian patent published in 2014 - IPC F16H9/26 F16H7/06 F16H7/18 

FIELD: machine building.

SUBSTANCE: invention refers to transmission mechanisms and can be used in power takeoff devices. A dynamic variator comprises a guide link in the form of a sprocket wheel (1) of internal engagement, an inertial element in the form of an endless chain (2), a driven link 93), a supporting wheel (5), a pressure roller (6). The endless chain (2) is set inside the sprocket wheel (1) and interacts with it along the inner side of its circumference. The supporting wheel (5) is installed on the driven link (3) and can shift in radial direction. At the guide link rotation the chain is involved in the rotation and is pressed to the inner surface of the sprocket wheel due to the centrifugal force. Shifting of the supporting wheel (5) in radial direction provides for infinitely variable adjustment of torque value at the output shaft and for chain tension in shutdown mode.

EFFECT: invention is aimed at infinitely variable adjustment of transmission ratio.
