Shaft Alignment, Dynamic Balancing Techniques & Measuring Tools

Machines that have been precision aligned run longer and cost less to run. Alignment greatly affects the life of bearings, seals, shafts, and couplings. Also, unbalance causes fatigue and reduces the life of bearings, and can make looseness and resonance conditions far worse. This course will bring you knowledge and skills in using a vibration analyzer/balancer, or a simple sheet of graph paper and a protractor, and balance a machine, without even having to remove it from the plant. You will learn how to recognize unbalance and set up the balance job for a successful balance.
 

Reverse-dial method
 

This course will equip you with the knowledge and skills so that you can use a dial indicator tool or a laser alignment system to precisely align two components together. You will learn how to recognize misalignment and successfully set up the alignment job. After reviewing the important reasons for performing shaft alignment, there will be a discussion about the pre-alignment checks and corrections, including how to identify and correct soft foot. The operation of dial indicators, and the cover the rim-face method and reverse-dial method will also be discussed. The process will be demonstrated and discussed, as well as how calculations are performed.
 

Laser alignment systems will be discussed; the benefits, basic theory of operation, and tips and techniques for successful use. And finally, there will be a discussion on how to move the machine and deal with all the problems that you are bound to encounter at some stage. We will also review how to deal with thermal growth and how to approach a larger machine train.
