Abstract
PURPOSE: To prevent generation of noise by constituting a reverse rotation preventing device used in a synchronous motor in such a manner that the cutout of a rotary cam coincides with that of a follower cam at the time of reverse rotation to prevent the reverse rotation and at the time of normal rotation the envelopes of both cams constitute a circle.
CONSTITUTION: When a rotor 10 normally rotates in the direction indicated by arrow A, a follower cam 17 relatively rotates in the opposite A direction with respect to a rotary cam 13 by the frictional force thereof with a reverse rotation preventing member, and the projection 16 of the cam 13 abuts against one end part of a depression 19. Accordingly, the cutout 18 of the follower cam 17 is positioned at a position delayed by an angle β from the cutout 15 of the rotary cam 13. Accordingly, the envelopes of both cams 13 and 17 from a complete circle, and the reverse rotation preventing member 20 slides smoothly on the outer peripheral surfaces of both cams 13 and 17. On the other hand, when the rotor 10 rotates reversely in the direction indicated by the arrow B, the follower cam 17 relatively rotates in a counter B direction, and the projection 16 comes into abutment with the other end of the depression 19 of the cam 27. When the tip end of the reverse rotation preventing member 20 drops into the cutouts 15 and 18, the reverse rotation of the rotor 10 is stopped.
