JPS54150551A - Multi-knuckle mechanism - Google Patents

Abstract

PURPOSE: To provide a multi-knuckle mechanism, whereby high speed operation is made capable in a small size and a light weight, as well as with an application capable of small powered motor, by a constitution so made as to enable the load smaller applied to the motor.

CONSTITUTION: Now with a motor 2, set in place to a fixed bench 1, rotating, a shaft 14 is rotated through a pulley 5, a belt 11 and a pulley 7. And if a motor 3, arranged in place on a rotary shaft of the shaft 14, rotates, a shaft 15 is rotated through a pulley 7, belt 12 and a pulley 8. Further with a motor 4, arranged in place on a rotary shaft of the shaft 15, rotating, a shaft 16 at the point end is rotated through a pulley 9, belt 13 and a pulley 10. Thus the shaft 16 is made positioning at high speed by the sum (or difference) of the motors 2 to 4. Though the above example is of constitution with the shaft in three stages, a consitution with the shaft in two stages and multi-stage more than three stages may be also capable. In this way, the applied load to the motor can be made small thus capable of presenting a high speed mechanism small in size and light in weight.
