Abstract
PURPOSE: To provide an electromagnetic clutch wherein an input rotary member is arranged concentrically on a single and the same output shaft so that the input from a single and the same power source can be outputted from the single output shaft in rotations in two directions at different speeds by means of electric signal switching.
CONSTITUTION: The first rotor 3 rotates in response to an input from the input rotary member 2. When a voltage is applied to an electromagnetic coil 8 of the first electromagnetic connecting mechanism A, the first rotor 3 is connected integrally to a hub 10 so as to take the input from the input rotary member 2 out of the output shaft 1 at a rotation ratio 1:1. Next, the electromagnetic coil 8 is deenergized. When a voltage is applied to an electromagnetic coil 20 of a second connecting mechanism B, a second sun gear 12 comes into a fixed state, whereas a second planet gear 16 rotates around the fixed sun gear 12 while revolving. Assuming that the tooth number ratio between the gears 12 and 16 is 2:1 and the tooth number ratio between the first planet gear 14 and the first sun gear 11 is 1.5:1, the output shaft 1 makes three rotations in the reversed direction.
