Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To make the structure of a disk rotary driving mechanism relatively simple with-out using balancing balls by constituting an automatic aliging mecha nism of balancing members freely rotatably supported at the center axis pro vided for a chucking pulley. SOLUTION: The shaft center of the center axis 13 of a chucking pulley 6 is roughly coincides with the rotary shaft 3 of a rotary driving means when the pulley 6 is attracted to a disk turntable 5 to become one body with the disk turntable 5 and the pulley is rotated together with the turntable in accordance with the rotation of the turntable 5. However an automatic aligning mechanism 7 performs an aligning action by allowing balancing members 12 to move to such a position as to cancel the imbalance in weight while combined rotary bodies have when the revolving speed of the rotary driving means exceeds a critical speed, at the revolving speed in which a shaft runout is to be generated, the speed is far from the critical speed.  For that reason, even when the revolving speed of the driving means does not reach the intrinsic critical speed, it is made possible to generate the pull-in phenomenon of the balancing members 12 by the resonance of such a vibration system.

Filed: 1978-03-10
Abstract: PURPOSE: To make possible the adjustment of instrument errors occurring depending upon the positions of the object being measured on the platform with a simple construction and obtain a robust measuring instrument by providing parallelogram deflection link and adjusting the height thereof.  
     CONSTITUTION: The load of the object being measured is transmitted to a moving beam 11 via stand. The load in the perpendicular direction of the object being measured and the moment of the magnitude corresponding to the position of the object being measured on a platform 17 are transmitted to this movable beam 11. Out of those the load in the perpendicular direction is transmitted to a load detecting member 8 via arm 10 and load fulcrum 9. On the other hand, the moment is absorbed by parallelogram deflection link 12. At this time, a difference in the magnitude of the load deteced by the load detecting member 8 occurs according to the position of the object being measured on the platform 17. This enables the instrumental errors thereof to be readily adjusted by adjusting the height of the parallelogram, i.e., the height of both flexible members 18, 18'.
