Alignment device
Abstract
Abstract A device for ascertaining axial and/or radial misalignment between the flanges of the power outlet or driving shaft of a large engine or heavy machine and the input or driven shaft of a massive accessory drive, i. e., a speed increaser or the like, with the flanges, not being intended to be mated one to the other directly but being rotatably connected by a high speed gear-type coupling, or the like. The device includes a pair of pointed rods which are suitable supported inwardly thereof, the points of the rods being urged outwardly against the driving and driven shafts so as to engage the respective rotating axes thereof, and at least a pair of measuring instruments that respectively have plungers which, when depressed, actuate meter movements having dials calibrated in mils. The measuring instruments are suitably supported at opposite ends of the main body of the device so that the respective plungers thereof may engage the face portions of the flanges of the driving shaft and the driven shaft. The device is intended to be manually rotated about its longitudinal axis which causes the plungers to rotate in unison about the respective face portions of the flanges of the driving shaft and the driven shaft for sensing the quadrants of these flanges that are misaligned and indicating the magnitude of misalignment on the respective dials thereof.
