METHOD TO MEASURE MISALIGNMENT OF SHAFTS Russian patent published in 2013 - IPC G01B5/24 G01B5/25 

FIELD: measurement equipment.

SUBSTANCE: meter, for instance, vernier callipers, is installed with metering legs on some surfaces of shafts (or a shaft clearance), then the vernier callipers are moved with metering legs onto opposite surfaces (sides) of shafts (or a shaft clearance), and the first readings of the meter are algebraically summed by the available method with the second readings, afterwards the doubled misalignment value is produced. A correcting value is introduced, which is equal to the sum of radii (or a shaft clearance) by the available method, metering legs are installed onto maximum distant surfaces of shafts, for instance, in the vertical position, and the vertical misalignment is determined, vernier callipers are rotated between these surfaces, the extreme misalignment is determined, and in the horizontal position - horizontal misalignment. After a specified time of operation of the mechanism, and also after a certain time of operation of the rolling stock they repeatedly measure misalignment in one spatial position of metered surfaces, and by difference of the first and repeated measurements they identify the total value of the wear, the clearance, the bearing and the shaft.

EFFECT: simplified process of measurement of misalignment and provision of capability to do measurements in hard-to-access places.
