Centering and alignment
Thread Content
As the title suggests, there is a photo showing the alignment of a chiller (the motor is equipped with sliding bearings). Please offer your guidance and discuss this matter. Wrong, wrong approach!
That’s fine, is there any problem? The spacing is a bit too large; if it is, a ‘fake shaft’ can be fabricated as a supplementary measuring aid. For reference.
The bearing shells need to be aligned using three indicators. Why is there only one gauge on the axial side?
First: two axial gauges. Second: Define the magnetic field lines clearly. Third: Synchronous rotation. Fourth: The axial scale should preferably be marked on the back side of the motor’s counterweight, at the same outer diameter.
This is the conventional alignment; it is necessary to consider stress-free alignment of the chiller.
A laser alignment instrument can be used; it is fast and provides accurate calculations.
Three tables are required for alignment in order to ensure the accuracy of the data.
We generally use a laser alignment tool for alignment
