2 Days:

Question
Is the correct alignment of rotating equipment a critical reliability factor in your plant? Would improved or refreshed skills in reverse dial shaft alignment methods help with maintenance team confidence and performance?

Who should attend?

Plant mechanics, millwrights and maintenance engineers are responsible for the health and reliability of rotating equipment. In this course, participants will learn how to accurately align direct coupled machine shafts.

The course begins with the fundamental principles behind shaft to shaft alignment and concludes with students conducting a series of alignment exercises using conventional alignment tools. The two methods; straight edge alignment, and reverse dial (cross-dialing) alignment will be covered. This two-day course is taught hands-on with standard alignment tools, demonstration models, and simulation software.

 

Learn How To:

 

WHY ALIGN?

Objective: List consequences from failure to align

Activity: Identify machine components that have failed due to misalignment

align6_500
Make a notable contribution to coupling, bearing and seal life! Minimize vibration and energy consumption!

 

ALIGNMENT THEORY

Objective: Describe the common types of shaft misalignment

Activity: Identify parallel offset and angularity

align15_500
Use simple alignment math and graphs! Take thermal offset into account!

 

PREPARING FOR ALIGNMENT

Objective: List steps to prepare for a shaft re-alignment

Activity: Use feeler gauges and dial indicators to test for irregular machine status

align9_500
Review recent maintenance records for valuable clues and begin safe lockout procedures!

 

MEASURING SOFT FOOT

Objective: Detect and correct soft foot conditions

Activity: Use magnetic base with dial indicator

soft_foot_b
Learn when and when not to correct foot!

 

DETECTING RUNOUT

Objective: Detect shaft and coupling runout conditions

Activity: Use magnetic base with dial indicator

coupling_runout
Can you proceed with alignment when there is shaft/coupling runout

 

STRAIGHT EDGE TECHNIQUES

Objective:Use basic tools to achieve rough alignment

Activity: Complete a hands-on rough alignment using straight edge techniques

align17_500
Put feeler gauges, vernier calipers and straight edges to good use to achieve initial roughed-in shimming and horizontal alignment!

 

REVERSE DIAL TECHNIQUES

Objective:Demonstrate correct reverse dial alignment routines

Activity: Complete two computer simulated and two hands-on alignment jobs using reverse dial techniques

align101_500
Setup brackets and indicators, correct for bar sag, take accurate measurements and make vertical and horizontal moves!

 

HORIZONTAL AND VERTICAL MOVES

Objective:Shim and make horizontal moves

Activity:Use shims and dials for both horizontal and vertical moves

horiz_move
Do you shim for vertical moves first, or make horizontal moves first?

 

INTRO TO ALTERNATIVE TECHNIQUES

Objective:List advantages of rim and face dialing and laser alignment
