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, chains, or sprocket teeth is detected.
Visual Pulley Alignment
D90, 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.
Digital Pulley Alignment
If you need accountability and documentation of the alignment, then the Easy-Laser XT190 will be the tool you need. The XT190 can be connected to your phone/tablet via the Easy-Laser XT Alignment App or can also be added to your existing Easy-Laser® XT440, XT660, and XT770 shaft alignment systems. Both interfaces will provide a visual representation of the misalignment, the capability of entering tolerances, and a PDF report for documentation purposes.
3 Quick Tips for Precision Alignment
- 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.
- Don’t forget to verify the proper tension of the belts (or chains) after the alignment.
