Shaft alignment systems specially developed for alignment of wind turbines.
Correct shaft alignment ensures that the rotating shafts of connected machines are perfectly aligned in relation to each other during operation. Misalignment can occur in horizontal or vertical planes and can result in excessive vibration, premature bearing and seal failures, and energy loss in rotating machinery.
Laser shaft alignment tools use precision laser technology to measure the relative position of two rotating shafts. Unlike dial indicators or straightedges, laser shaft alignment tools offer fast, highly accurate, and repeatable results. Advanced alignment systems can also measure thermal growth and dynamic machine movement. The system generates full documentation of the results, which is often a requirement.
A laser shaft alignment tool typically consists of two measuring units with suitable brackets, a display unit, and alignment software that guides the user through the alignment process.
There are two main types of shaft misalignment:
In practice, a mix of both angular and offset misalignment is the most common. The shaft alignment tool helps you determine what the problem is and correct it.
If misalignment is not corrected, it can lead to serious problems such as increased vibration, damaged bearings and couplings, and unplanned downtime. You can read more about typical symptoms in our article 5 symptoms of shaft misalignment.
To correct shaft misalignment, you should follow a clear step-by-step method to get accurate and lasting results. It begins with pre-alignment checks. This includes inspection and cleaning of the mounting surfaces and replacing old shims. Next, you do a rough alignment and soft foot check. Once ready, the measurement process is carried out using laser measurement equipment that collects precise alignment data. Based on these results, the necessary corrections are made, typically by adding or removing shims and adjusting the machine’s position horizontally or vertically. After the adjustments, a verification step ensures that the alignment is within the required tolerances.
If the alignment problem still cannot be resolved, a dynamic measurement may be required to determine whether external forces – such as pipe strain or thermal growth – are affecting the machine.
When machines are properly aligned, they consume less energy, as there is minimal friction. This not only reduces operating costs but also contributes to more sustainable operations.
Proper shaft alignment also extends the life of mechanical components such as bearings, seals, and couplings by minimizing unnecessary wear. As a result, equipment becomes more reliable, and the risk of unexpected breakdowns becomes much less likely. It also improves workplace safety by reducing vibration-related issues.
In the long run, aligned machines require fewer repairs and allow for longer maintenance intervals. This means lower overall maintenance costs.
If you want to increase the efficiency and lifespan of your machines, make precision shaft alignment a part of your regular maintenance program.
