Laser alignment system Easy-Laser® Wind

shaftturbinefor rotating machinery

Easy-Laser Wind shaft alignment systems are developed for precise alignment of wind turbine drive trains. They enable alignment of the gearbox and generator even with the coupling removed and the rotor locked, and are intended for use during installation and for ongoing field maintenance, making them suitable for service companies.


Overview

• Bracket kits allow alignment of gearbox and generator with the coupling removed and rotor locked, meeting safety requirements from many turbine manufacturers.
• Systems support both initial installation and recurring maintenance in the field and fit multiple powertrain models from major turbine OEMs.
• Measuring units and display can be supplied together with bracket kits, or the installation kit can be delivered as a mechanical bracket kit only if the user already owns measuring units and display.

Systems for shaft alignment with locked rotor

• System for Vestas tubines: This shaft alignment system consists of three different kits (sold separately): one general installation kit, one supplement service kit for use on smaller turbines, plus one upgrade kit. The installation kit can be delivered without the measuring units and display unit etc. (then called Mechanical bracket kit), if you already own those. For use with both E and XT series measuring units.
• System for Siemens Gamesa turbines: This solution includes a kit with display unit and measuring units (E-series) and brackets to measure with the coupling in place, as well as a bracket kit (for both E and XT series) for measurement with the coupling removed. The kits are sold separately or as a package.

Shaft alignment with rotating shaft

• When aligning with the coupling in place the shaft must be able to rotate (for example via servo drive) and be safely stopped with the brake.
• The EasyTurn measurement program is included in all Easy-Laser systems and requires only minimal shaft rotation to determine alignment condition.
• Standard rotating-shaft systems include Easy-Laser XT660 Shaft SG1 (version with brackets for Siemens Gamesa) and Easy-Laser XT660 Shaft WMB (version with brackets for multiple brands and models).
