Alignment analyzer with graphical alignment tolerance display
First Claim
1. An alignment analyzer for facilitating the alignment of at least one machine set including first and second rotatable shafts connected respectively to first and second machines employing an alignment fixture for measuring a pair of offsets at a plurality of shaft rotational positions to establish a measured data set, said alignment analyzer comprising:
- a display device capable of displaying a graphical representation in a coordinate system having a first coordinate representing offset misalignment and a second coordinate representing angular misalignment; and
elements operating to calculate, based on the measured offset data set, the amount of offset misalignment, if any, and the amount of angular misalignment, if any, of the shafts in at least one plane, and to display combined offset and angular misalignment as a point in the coordinate system on said display device, said point being positioned with respect to the first coordinate based on the calculated amount of offset misalignment and being positioned with respect to the second coordinate based upon the calculated amount of angular misalignment.

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.
