Abstract

An alignment analyzer for facilitating the alignment of a machine set including co-rotatable in-line shafts includes a display device on which separate offset misalignment and angle misalignment components are displayed as a single point in an x-y coordinate system. The coordinates of the point are the individual misalignment components. Also displayed on the display device are curves representing "acceptable" and "excellent" tolerance ranges. The displayed point and the curves together indicate whether the combined offset and angular misalignment is within or without the "acceptable" tolerance range, and whether the combined offset and misalignment is within or without the "excellent" tolerance range. Also disclosed is a method whereby the amounts of offset and angular misalignment in a given plane are computationally combined to determine a combined misalignment amount for that plane, and then compared either to a value representing a tolerance limit for "acceptable" alignment, to a value representing a tolerance limit for "excellent" alignment, or to both values.
