Claims

[Claims for Utility Model Registration] 1. A rotating device consisting of a rotating shaft 1 and rotating bodies 2, 3, and 4 attached to the rotating shaft 1 and rotating integrally with the rotating shaft 1, including the rotating shaft 1 or the rotating body 2. , 3 and 4 are formed with female screw holes 6 extending from their outer peripheral surfaces toward the center,
A rotational balance correction mechanism for a rotating device, characterized in that a male screw 7 is screwed into the female screw hole 6, and the rotational balance is corrected by screwing the male screw in and out. 2. The rotating device according to claim 1, wherein the rotating body is collars 2 and 3 fixed to the outer periphery of a rotating shaft, and a rotating grindstone 4 fixed to the outer periphery of the collars 2 and 3. Rotation balance correction mechanism. 3. A rotational balance correction mechanism for a rotating device according to claim 1 or 2, in which a locking prevention mechanism 8 is provided between the inner bottom surface of the female threaded hole 6 and the inner end of the male thread 7. . 4. The rotational balance correction mechanism for a rotating device according to claim 3, wherein the locking prevention mechanism is a spring that biases the male screw 7 in one direction.
