Set the initial value for coupling alignment to 0; it should not be 0 when the disc rotates 360°
Thread Content
RT, what I want to ask is: when the initial value is set to 0, after rotating the disk 360°, it occasionally shows a value other than 0 – it deviates by 1–2 tracks. What could be the reason for this? Is it allowed for this situation to occur in practice? What impact will it have on the measurement results?
When using a gauge to adjust the timing, both the stiffness of the bracket and gravity can cause the phenomenon you mentioned to occur.
Set the initial value for coupling alignment to 0; if the rotation of 360° does not result in a value of 0, it indicates that true alignment has not been achieved yet. Factors such as the stiffness of the supports, gravity, and the bearings also need to be taken into consideration
During alignment, both couplings must rotate simultaneously, and the alignment point (the point indicated by the dial indicator) must be synchronized. In such a situation, if the problem you mentioned occurs, factors such as the rigid deflection of the dial indicator holder and gravity can be taken into consideration.
In practice, one to two threads are generally fine unless extremely high precision is required; after all, it’s not possible to ensure that you return to the original position after rotating 360 degrees, as human operation introduces systematic errors.
The shaft of the magnetometer base has moved, or the watch mount is not properly secured to the shaft; the watch mount lacks stiffness and bends, and the two shafts rotate out of sync, resulting in an angular deviation. Try using a laser alignment tool; it’s quite reliable. Mechanical type; when requirements are not high, an error of 1-2 units is still acceptable
To align the two half-couplings, they need to rotate together; one full rotation does not bring them back to their original position. Gravity and the strength of the watch case must also be taken into account. For important equipment, it is still recommended to use a laser alignment tool for alignment
