METHOD AND DEVICE FOR TRANSMISSION OF ROTATIONAL MOVEMENT Russian patent published in 2011 - IPC H01H9/00 

FIELD: electricity.

SUBSTANCE: device for transmission of rotational movement includes movement conversion unit that includes intermediate element (3) connected with rotation axis (3a) with the possibility of rotating round it, mechanical energy accumulating unit (5) in a form of spring device, unit of stretchable/compressible spring connected with solid clamp and movable clamp and means of transmitting mechanical energy accumulated in spring device to driven element (2) via drive shaft (2a). Note that intermediate element (3) contains cam drive roller interacting with energy accumulating unit (5). Movable clamp is equipped with rolling element that contacts with drive roller periphery. Movable clamp can be performed with the possibility of moving in radial direction parallel to plane of drive roller. Method of transmission of rotational movement to element includes transmission of mechanical energy accumulated in spring device to drive shaft. Application of proposed device for rotational movement transmission is performed with the possibility of winding switch contacts' control under load in transformer or stabiliser.

EFFECT: improvement of rotational movement transmission use.
