Title:
ROTARY CONTROL MECHANISM
Document Type and Number:
Japanese Patent JPS6121431
Kind Code:
A
Abstract:
PURPOSE:To make a smooth rotation control by displacing a plurality of centrifugal weights disposed in the periphery of a disc in the centrifugal direction by action of centrifugal force when the disc is rotated more than fixed to press a plurality of bearing balls to the inner wall of a casing. CONSTITUTION:When a rotary shaft 1 and a disc 2 fixed thereto are rotated less than fixed, the respective centrifugal weights 4a-4d are kept in such a manner as to lie along the peripheral edge 3 of the disc 2, so that the respective bearing balls 10a-10d collide with corresponding circular-arc projection ends 11 to exhibit a bearing function. On the contrary, when the disc 2 is rotated more than fixed, the respective centrifugal weights 4a-4d are displaced with a supporting point of a shaft pin 5 in the centrifugal direction by centrifugal force, and the longitudinal portions 6 thereof are pushed out to the inner wall of a casing 9. Accordingly, the small portions 7 of the respective centrifugal weights 4a-4d are turned in the centripetal direction to open passages for the bearing balls 10a-10d, so that the bearing balls 10a-10d are moved to the longitudinal portions 6 of the centrifugal weights 4a-4d to gradually brake the disc 2.
