Practical Balancing and Shaft Alignment

Why Balance?

All rotating components experience significant quality and performance improvements if balanced. Balancing is the process of minimizing vibration, noise and bearing wear of rotating bodies. It is accomplished by reducing the centrifugal forces by aligning the principal inertia axis with the geometric axis of rotation through the adding or removing of material.

BALANCING WORKSHOP

……………………………………………………………………………………………………

COURSE OVERVIEW

This course covers single- and two-plane balancing techniques for both rigid and flexible rotors. It includes both field balancing and shop (balancing machine) balancing. Topics such as pre-balance checks, influence coefficients, balance quality and tolerances, residual unbalance testing and case histories are included. The workshops and demonstrations, scheduled throughout the training course, are used to illustrate theory and applications.

A PRACTICAL APPROACH TO SHAFT ALIGNMENT

……………………………………………………………………………………………………

COURSE OVERVIEW

This course will discuss the importance of alignment, how to: correct soft foot, check runout, align two pieces of rotating machinery using dial indicators, and to review all the currently used alignment equipment and techniques (e.g. lasers and electromechanical systems).  Material from other courses on vibration analysis and anti-friction bearings are usually interjected to supplement the content and assist the attendee in understanding how alignment affects overall machinery performance.

WHY ALIGN?

Understanding and practicing the fundamentals of shaft alignment is the first step in reducing unnecessary vibration, reducing maintenance costs, and increasing machine uptime. Misaligned rotating machinery has caused, and will continue to cause, a tremendous financial loss to every industry worldwide.

TOPICS INCLUDE:

• Alignment methods and accuracies of each

• Equipment installation “tips and pointer”

• Soft foot condition and how to correct it

• Coupling types and alignment requirements of each

• Dial indicator method of alignment

o Tool set up for dial indicator method

o Bar sag calculations and offsets

o Calculations for shim requirements and machine offsets
