FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, namely to electromechanical control devices, and can be used to convert rotary motion of input shaft into intermittent (discrete) motion of output shaft by means of assembly fixed on output shaft. Proposed device comprises base, input and output shafts and winding spring. Two pairs of spring-loaded locking pawls are arranged on the base to turn through a limited angle. Cam is rigidly connected to the input shaft passing through the centre of the base; one of the ends of the wind-up spring is fixed on the cam, the other end of this spring is fixed on the rotary drum with projections. Rotary drum is rigidly connected to the output shaft; at that, the output shaft is located coaxially with the input shaft, and the force of pressing the protrusions of the rotary drum to a pair of locking pawls, which rest on the cam protrusions, is provided by the wind-up spring. Rotary drum is retained from possible rotation in the opposite direction by spring-loaded latches, which have the possibility of turning through a limited angle.
EFFECT: enabling conversion of continuous rotary motion of the input shaft into intermittent rotary motion of the assembly with its further fixation fixed on the output shaft, including at increased mechanical effects.
