Abstract
The variable air-gap type driving detector of the present invention for obtaining low speed and high torque outputs required to drive, for example, joints of industrial robots is provided with an elastic supporting means 22, whose one end is supported on a base stand 21 , for supporting a rotor 5 so as to restrain the rotor 5's autorotation; and an eccentric supporting meals, whose rotation shaft 23b is supported on the base stand 21 in a freely rotatable state, and an outside of whose eccentric shaft 23a is supported inside the motor 5, and further whose rotation shaft 23b rotates with the revolution of the rotor 5; and the driving device of the invention becomes simple in structure and small in size by being composed of using no cranks or only a crank. Also, the driving device of the invention is provided with a first gear supported on a base stand in a freely rotatable state; and a second gear, linked with a rotor, for rotating the first gear by revolving inside the first gear with the revolution of the rotor; therefore the revolution movements of the rotor become capable of being taken out from the first gear as rotation movements with only an eccentric supporting means.
