Laser Shaft Alignment

The term 'Offset' in shaft alignment refers to the

• gap between shaft centers.

• soft foot movement on the movable machine.

• axial movement between coupling hub.

• distance between the front foot and back foot of the movable machine.

Which one of the following shaft alignment methods is a faster method that provides alignment up to 0.001mm tolerance?

• Straight edge method.

• Laser shaft alignment method.

• Reverse dial indicator method.

• Rim and face dial indicator method.

The standard tolerance of shaft alignment is determined by the rotational speed.

• True

• False

Laser shaft alignment system requires a minimum of 4 measurement points to do shaft alignment.

• True

• False

Which one of the following items is NOT needed when using the laser shaft alignment system?

• Reflector.

• Transducer.

• Dial indicator.

• Measuring tape.

Which one of the following statements is FALSE for the laser shaft alignment system?

• The key dimensions of the machine must be entered.

• The stationary and movable machines must be identified.

• The soft foot of the movable machine must be corrected.

• The centering of laser beam is not necessary before alignment.

What is the maximum number of shims to be added in order to avoid soft foot of the movable machine?

• 2

• 3

• 4

• 5

'Live' adjustment to correct shaft misalignment is NOT possible with laser shaft alignment system.

• True

• False

The laser beam of the laser shaft alignment system is NOT affected by gravity.

• True

• False

Which one of the following practices is recommended when a large diameter coupling blocks the laser beam from the transducer?

• Fabricate a larger bracket to mount the transducers.

• Add one more set of transducer and reflector onto the same shaft.

• Remove the coupling hubs. before mounting the transducer.

• Remove a coupling bolt to allow the laser beam to pass through the bolt hole.
