Checking perpendicularity between face and centerline of a shaft 2




The face to be checked is the pink shaft bottom.

Turn the shaft several revolutions while keeping a continuous contact between the shaft and the brown pin (for example by setting the base inclined). Get max and min values (E1 and E2) shown by the indicator.

Non-perpendicularity P = (E1-E2)/2A

A: center distance of indicator and the brown pin.
