Filed: 1980-03-28
Abstract: PURPOSE: To simplify the construction and control of a chuck, by transmitting motive power from a motive power source through a planet gear to open and close the jaws of a scroll chuck and rotate a workpiece.  
     CONSTITUTION: The rotation of a sleeve 6, which is caused by external motive power, is transmitted to the body 14 of a chuck and a scroll plate 16 through internal gears 9, 10 engaged with a planet gear 8 supported on the eccentric part 7 of the sleeve 6. When the chuck body 14 is secured by a brake 12 and the sleeve 6 is rotated, the internal gear 10 is rotated because the internal gears 9, 10 differ from each other in the number of teeth. As a result, the scroll plate 16 is rotated to move jaws 19 to chuck a workpiece. When the brake 12 is released, the internal gears 9, 10 are rotated together to transmit torque to the workpiece. According to  this constitution, the opening or closing of the claws and the movement of the workpiece can be alternatively performed by a single motive power source. This results in simplifying the construction and control of the chuck.
