Wind power industry

Alignment gets things spinning

There are many applications for the EasyLaser® systems in the wind power generation industry. The fact is that Easy-Laser® is one of the world’s largest suppliers of laser based measurement systems to the wind power industry. This applies to, for example, systems for the alignment of gearboxes and generators, both in production and out in the field during continuous maintenance work.

Another large application is the system for measuring flatness on tower flanges. For manufacturers of vanes, we also supply equipment for measuring and aligning the centre line of the jigs, as well as their squareness. Several of the measurement systems have been especially adapted for the companies’ specific machines. This type of work is carried out quickly thanks to our own development department and modern workshops.

Measurement of flatness on tower flanges

The measurement of flatness/twist on circular planes such as flanges is also based on the use of three reference points, situated at intervals of 120° around the circle. Decide the number of measurement points and which three will be the reference points on which the laser plane will rest. All measurement results displayed are now relative to the three selected reference points/laser plane. It is possible to measure both inner and outer circles on the flange (ID/OD), with up to 300 measuring points. You can then display the graph in the EasyLink (Version 2.2) program, and also work further with the measurement values to test different settings; best fit to centre, best fit around zero, best fit all positive/all negative, best fit absolute values etc.

Evaluate directly in real 3D

New Easy-Laser® E910 and E915 flange measurement systems offer a new and more effective way of working. You can see the result as a 3D image in the display unit immediately after measuring and then evaluate the result. This can also be done directly on site without having to stop to go to a PC with separate analysis programs, which was the case previously. This makes production much more efficient. Bluetooth® detectors enable you to work wirelessly and with more freedom.

Shaft alignment

When it comes to wind power generation, we are talking about the alignment of generators and gearboxes. Large forces are in action in a wind turbine. The safety of the maintenance technicians is therefore of the utmost importance. With the Easy-Laser® shaft alignment system the generator and gearbox can be aligned with the coupling dismounted and the brake locked.
