ABSTRACT:
An assembly for providing alignment growth measurements for coupled shafts includes laser alignment measurement equipment and a mounting assembly for attaching the laser alignment measurement equipment to bearing housings of cooperating coupled shafts. The mounting assembly includes a bracket for attaching directly to the bearing housing. A first mounting disk is attached directly to the bracket. A second mounting disk is attached to the first mounting disk and is universally pivotally adjustable about a center pivot ball between the mounting disks. Tilt-adjusting screws are placed at equally spaced quadrantal positions to effect the pivoting of the second mounting disk. A cylindrical insert is attached to the second mounting disk and receives a detachable end cap. The end cap is adapted to receive the laser measuring assembly. Accurate measurement data is provided by a plurality of pairs of cooperating tooling balls. An outside micrometer is used to measure the gap. To gather the information required for determining alignment, the laser equipment is initially zeroed before beginning the thermal cycle and the gaps between cooperating tooling balls measured. Following the end of the thermal cycle, the laser equipment is re-zeroed by pivotally adjusting the mount assembly. The change in gaps between cooperating tooling balls is measured and alignment growth information calculated.
