INTRODUCTION
Perfect alignment of machinery shafts is crucial to prevent premature
bearing failure, shaft fatigue, sealing problems and vibrations. It
further reduces the risk of over-heating and excessive energy
consumption. The SKF Shaft Alignment Tool 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.
1.1
Principle of operation
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 misalignment or angular misalignment
causes the two laser lines to deflect from their initial relative position.
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 followed live.
