TENSION TRANSMISSION FOR TENSIONING ENERGY ACCUMULATING SPRING OF ENERGY ACCUMULATION SPRING DRIVE Russian patent published in 2021 - IPC H01H3/30 

FIELD: machine building.

SUBSTANCE: invention relates to tension transmission (1) for tensioning energy accumulating spring of energy accumulation drive. Tensioning gear (1) includes tensioning wheel connected to energy-accumulating spring, intermediate shaft (2) connected with tensioning wheel and driven by tensioning motor, intermediate wheel (4), connected to intermediate wheel (4) free running mechanism (3) and cam clutch (20), which connects free running mechanism (3) for tensioning energy-accumulating spring with intermediate shaft (2) and in tensioned state of energy-accumulating spring disconnects it from intermediate shaft (2). Clutch coupling (20) includes first coupling cam (12) coupled with free movement mechanism (3) second clutch cam (11) connected without possibility of rotation with intermediate shaft (2), and located between clamps (11, 12) of coupling and synchronous ring (15) connected without possibility of rotation with first cam (12) of coupling. Synchronous ring (15) connects at rotation relative to second clutch cam (11) in first direction of rotation about axis of rotation (21) with geometrical closure with second cam (11) of coupling.

EFFECT: technical result is improved tensioning transmission.
