Maintenance departments periodically schedule maintenance checks on their belt- or chain-driven equipment in order to confirm that a good alignment exists between the pulleys or sprockets, especially if evidence of premature wear on the belts or sprocket teeth is detected.
For this task a Dotline Laser, Sheavemaster or Sheavemaster Greenline laser pulley alignment tool is ideal. It indicates misalignment in all three degrees of freedom (axial offset, horizontal angularity and twist angle) instantly.
Always mount your laser pulley alignment tool on the smaller pulley and the targets on the larger one, for maximum resolution. Ensure that the mounting surfaces (pulley faces) are free of dirt or rust, and don’t forget to verify the proper tension of the belts (or chains) after the alignment.
