Laser Shaft Alignment Flashcards
what is the disadvantage of a duel beam shaft alignment laser?
it requires 2 cables
how many location readings must be taken to complete an alignment?
3, 45 degrees apart
what is an inclinometer?
it is a tool used to make sure the angular positions are correct
what planes do we calculate alignment tolerances in?
vertical and horizontal
what is the main safety consideration for visible laser beams?
do not look into the beam
when using a piano wire in the horizontal plane, a millwright must use the proper:
weight
wire size
sag chart
what is the advantage of using lasers for alignment?
eliminate bar sag
can cut through smoke and fog
which shaft is the laser transmitter mounted on?
the fixed machine
how does coincidence level work?
use a series of mirrors and a split bubble to confirm level
what are the four key laser components?
transmitter
reflector
mounting brackets
control unit
which part of the laser system performs misalignment calculations?
the microprocessor control unit
why should you shield laser alignment systems from strong heat sources?
the heat can cause the beam to wander and cause distortion of the laser head
what are three advantages of laser bore alignment over piano wire?
saves time
no bar sag
wind has no effect
