The drive train of a WTG not only ensures a high energy yield: during its operation, it is exposed to energies that are just as strong – the axial forces of the rotor. Generally, these are safely absorbed by the main bearing. But even the life of a main bearing is limited.

In the event of a bearing failure, the resulting bearing play pushes the rotor and main shaft axially towards the gearbox. The position of the gearbox can move by several millimeters. The entire force is now applied to the next point of contact – the planetary gear bearing, which cannot withstand such a force in the long run. The consequence: expensive bearing damage in the gearbox as well as an interruption in the operation of the WTG.

In order to prevent major damage to the gearbox, the position of the gearbox must be continuously monitored. To achieve this, we install sensors directly on the two gearbox mountings seated inside the structure-borne noise insulation. These sensors register any changes in the position of the gearbox and convey these via the WTG controls to the remote monitoring system. In the event of a change in position, the WTG is automatically stopped. The gearbox thus remains undamaged and by inspecting the situation on site, the damage to the main bearing can be identifi ed. Generally, the bearing will have to be replaced. The costs for this are, however, considerably lower than those of also replacing the gearbox.
