Abstract

PURPOSE: To obtain a constant number of rotation by synergistic effect of governor effect due to wind pressure and braking effect due to the magnetic force which acts between a rotary disk similar to a governor which uses wind pressure and a brake gear equipped near the said disk.
CONSTITUTION: A rotary disk 5 composed of the magnetic substance such as soft iron is provided on a rotating shaft 4 connected with a driving shaft 2 wound by a spring 1 through a special gearing 3 and at the location near the rotary disk a permanent magnet 7 is fixed to a supporting plate 6 facing a rotating body 5. The permanent magnet 7 acts as a brake gear for the rotating body. Even when the spring is wound fully the permanent magnet 7 restrains speed of rotation of the rotating shaft 4 and controls revolutions of a rotation unit A connected with the driving shaft at a constant. Braking force can be controlled by regulating the distance between the permanent magnet 7 and the rotary disk 5 through manipulation of a knob 10.
