PURPOSE:To achieve a higher workability eliminating the eccentricity of a thin cylinder, by forming a step on a jig body to be fitted into the end of the thin cylinder while a projection is extended to the inner diameter of the jig body from the slit surface thereof. CONSTITUTION:A step 8 is provided on a jig body 6 to be fitted into the end of a thin cylinder. A projection 9 is extended to the inner diameter of the jig body 6 from the surface of a slit 7 thereof 6 and the slitted part thereof are put together with a bolt 10. On the other hand, a balance weight 11 is arranged on the inner surface of the body 6. In addition, the other diameter of the step 8 can be somewhat increased with the width of the slit 7 is adjustable by a screw 10. With such an arrangement, the thin cylinder can be prevented from coming off which rotating on a dynamic balancing machine. Moreover, very limited variance in the inner diameter of the thin cylinder will cause negligibly limited errors in the unbalance regardless of slight increase or decrease in the outerdiameter of the equipment. This eliminates the eccentricity of the thin cylinder thereby achieving a higher workability. |
