Reverse Double Dial Alignment (A8306)
About this class
Learn how?to use the reverse double dial alignment procedure to determine and correct misalignment as well as how to take dial indicator readings.
Prerequisites
This lesson is designed for participants familiar with precision measuring instruments, specifically dial indicators, and the principles of reverse double dial alignment. A basic understanding of the principles and practices of predictive maintenance is also required.
Description
This lesson shows how to use the reverse double dial alignment procedure to determine and correct misalignment as well as how to take dial indicator readings. The lesson also teaches how to calculate the necessary vertical and horizontal adjustments and how to verify the results. Emphasis is on good record keeping, the importance of accurately reading the dial indicators, and performing the calculations correctly to ensure that proper alignment is achieved.
Objectives
Measure bracket sag and other dimensions necessary to calculate misalignment. Mount an alignment rig correctly on two shafts. Take a set of sweep readings. Determine if vertical misalignment exists. Shim a machine to correct vertical misalignment. Determine if horizontal misalignment exists. Calculate the distance to move a machine to correct horizontal misalignment. Verify that equipment is aligned within specifications.
