Shaft/coupling misalignment is responsible for over half of all excessive vibration in machines. The resulting premature bearing and seal wear has a significant effect on machine life, production availability, and ultimately, your plant’s profitability. Precise and consistent alignment of all your rotating equipment will help you reduce maintenance costs and unscheduled downtime, increase process quality, and extend machine life. This course teaches alignment principles (applicable to all methods and machinery) in practical, easy to understand terms and also provides hands-on experience performing precision alignment.
Reverse dial indicator or laser alignment courses are offered depending on the needs of the client. Subject coverage is similar for both versions and each includes a full overview of all current alignment practices.
Learn the Fundamentals of Precision Alignment
Learn what precision alignment is and why it is so important. Seemingly complex, technical topics are presented in workable, “nuts-and-bolts” language. The common alignment methods are examined, and their relative benefits and limitations are compared. The basic steps for properly setting up an alignment project, ensuring accurate readings, and collecting and interpreting data are presented. Understanding these processes, craftsmen and technicians can achieve desired precision alignment tolerances in a timely and repeatable manner.
Learn Alignment Calculations that Save Time and Eliminate Errors
Alignment calculations are simplified into step-by-step instructions for use with graphical methods or computer programs. Learning the graphical approach reinforces basic alignment concepts and helps the participant “see” the misalignment and the adjustments necessary to correct it. Specially designed graph paper and forms are provided that facilitate accurate results, allowing for offsets that may be required due to machine thermal growth and other environmental factors.
Align Machines Using the Reverse Indicator or Laser Methods
Extensive hands-on alignment training strengthens understanding of the methods and concepts presented in the course. Exercises include the proper placement of shims, soft foot compensation, techniques for machine moves, and handling shaft problems. Alignment tolerances and the elements of an effective alignment program are stressed: enabling your technicians to make the right moves the first time.
