Laser Alignment
Misalignment is the deviation of the relative shaft position from the collinear axis of rotation when equipment is running at normal operating conditions.
Types of misalignment.
- Offset Misalignment
- Angular Misalignment
- Combination Misalignment – Offset and Angular
Factors that may cause misalignment?
- Premature bearing, seal, shaft and coupling failure.
- Loose foundation bolts.
- Excessive oil leakage at bearing seals.
- High radial and axial vibrations.
- Loose or broken coupling bolts.
- High casing temperatures near bearings.
- Loose anchoring bolts.
- Excessive grease inside coupling guard.
Laser Alignment Frequently Asked Questions
Yes. This type of coupling can only absorb a small amount of misalignment. (Maximum 4 degrees).
No. Always check the alignment especially on two pole motors (3000K).
No. As this unit is coupled to the pipes and fixed to the base frame distortion will influence the alignment. Check the alignment prior to installation.
Yess it does. Misalignment generates heat and forces to the bearings and coupling. Turning the driven unit requires more torque and power consumption will increase.
