An indicator for use in monitoring and determining axial deflection or positioning of a coupling, e.g., of the flexible diaphragm type, wherein a pair of suitably configured indicia such as stepped edge decals are located on opposite ends of the coupling torque tube or spacing member adjacent each coupling hub. Initially each coupling guard ring covers a portion of the indicia, while leaving the remainder exposed. This is indicative of the normal nondeflected position of the diaphragm or similar flexible coupling component. As the shaft rotates, a stroboscope is employed to flash a light frequency corresponding to the rotational speed of the shaft and in the event there is axial misalignment the indicia will appear to deviate from their normal nondeflected position such that more or less of the indicia will be seen as the torque tube or spacing member is observed with the strobe light applied to it. |
