ABSTRACT:
A speed reduction clutch mechanism which enables construction of an inexpensive driving system of a simple structure and can be conveniently incorporated in a driving system of an arm of a robot of the direct teaching type. The mechanism includes a reduction gear including input and output shafts and a body frame supported for rotation around a common axis. The input shaft is connected to an output shaft of a motor. A first arresting mechanisms is provided for arresting rotation of the body frame of the reduction gear. When the first arresting mechanisms is not in its arresting condition, a second arresting mechanisms couples the body frame to the output shaft of the reduction gear thereby to establish an integrally rotating relationship between the output shaft of the reduction gear and the output shaft of the motor. A switching mechanisms alternately renders the first and second arresting mechanisms operative. Where the mechanism is incorporated in a driving system of a robot of the direct teaching type, the output shaft of the reduction gear is connected to the arm.
