Abstract
PURPOSE: To change the effective diameter of a pulley by changing the opening angle of the pulley to shift a belt radially.
CONSTITUTION: When pulley plates 4 and 5 start to rotate and exceeds the prescribed number of revolutions, the centrifugal force given to a centrifugal weight 13 exceeds the force given by tension coil springs 14, and rotates a rotary plate 11 anticlockwise around a bolt 9. As the bolt 9 is rotated, the gap between nuts 7 and 8 mounted on male screws 9a and 9b of the bolt 9 is expanded, and thereby, the effective diameter of a belt 18 wound between pulley plates 4 and 5, that is, the diameter of the pulley is reduced. As the number of revolutions of the pulley further increases, the centrifugal weight 13 is slided upward in the guide slit of the rotary plate 11 without rotating the rotary plate 11. As long as the weight 13 rises from the bottom to the top of the slit, that is, while the number of revolutions of the pulley is between n1 and n2, the diameter of the pulley is kept constant.
