Abstract
The method and apparatus for correcting the dynamic balance of a rotating body, whereby the correction of the dynamic balance of a rotating body is achieved by fixing a correcting agent on the rotating body after the position of the dynamic unbalance and the amount of the dynamic unbalance in the rotating body are measured, are so constructed as to detect whether or not the correcting agent fixed on the rotating body is protruding from a prescribed configuration of the rotating body. Therefore, the method and the apparatus are capable of not only correcting a dynamic unbalance of a rotating body, but also detecting the protrusion of the correcting agent fixed on the rotating body.
Claims25
A method of correcting the dynamic balance of a rotatable body, comprising the steps of:
- (a) measuring the location and amount of a dynamic unbalance in the rotatable body;
- (b) applying a balancing composition to the rotatable body dependent on the measurement of the location and amount of the dynamic unbalance in the rotatable body;
- (c) determining the state of the dynamic balance of the rotatable body and detecting the existence of a protrusion of the balancing composition applied to the rotatable body beyond a predetermined dimension of the rotatable body by irradiating a beam of light in the direction of a tangential line of a predetermined outside configuration of the rotatable body while rotating the rotatable body;
- and
- (d) hardening the balancing composition applied to the rotatable body.
An apparatus for correcting the dynamic balance of a rotatable body, said apparatus comprising:
- a measuring part which measures the location and position of a dynamic unbalance of the rotatable body;
- an applying part which applies an amount of a balancing composition on the rotatable body dependent on the measurement taken by said measuring part;
- and
- a protrusion detecting part which detects the existence of the balancing composition on said rotatable body beyond a predetermined dimension of said rotatable body.

- (a) supporting the rotatable body such that the body may rotate about the rotation axis;
- and
- (c) detecting the existence of protrusion of the balancing composition beyond a predetermined dimension of the rotatable body by bringing a detecting member into close proximity of the rotatable body such that the detecting member will make contact with the balancing composition if a protrusion is detected while the rotatable body is rotated about the rotation axis.
A protrusion detecting apparatus for detecting the existence of protrusion of a balancing composition beyond a predetermined dimension of a rotatable body, the balancing composition having been placed on the rotatable body for correcting a dynamic balance of the rotatable body, said protrusion detecting device comprising:
- supporting means for supporting the rotatable body in such a manner as to permit its rotation round a rotation axis thereof;
- driving means for rotating said rotatable body round the axis;
- and
- detecting means for detecting the existence of protrusion of the balancing composition beyond the predetermined dimension of the rotatable body while said rotatable body is being rotated by the driving means.
