Perf
ect alignment of machiner
y shafts is cr
ucial to prevent premature
bearing failure, shaft fatigue, sealing problems and
vibrations. It
further reduces the
risk of
over
-heating and excessive energ
y
consumption. The SKF
Shaft Alignment T
ool TMEA
2 offers an easy
and accurate way of adjusting two units of rotating machinery so that
the shafts of the units are
in a straight line.

The TMEA 2 system uses two measuring units both provided with a
laser diode and a
positioning detector
. As
the shafts are rotated
through 180°
any parallel misali
gnment or angula
r misalig
nment
causes the two laser lines to deflect from their
initial relative positio
n.
The measurements from the two positioning detectors automatically
enter the logic circuitry inside
the display unit, which calculates the
misalignment of the shafts and advises on corrective alignments of
the machine
feet.
After a straightforward measuring procedure, the tool immediately
displays the misalignment of the shafts
and the necessary
corrective
adjustments of the feet of the machine. Since the calculations are
done in real
time the progress of
the alignment can be
follo
wed live.
