Spur Gears for PIT Turbines

Developed specifically for pit turbines, these gears are of robust and compact design and are around 99% efficient. This is achieved by optimized gearing for the specific application, low-friction bearings and precisely measured amounts of lubricating oil. In combination with a gear system support halfway along the shaft, an intelligent fin design ensures that forces from the turbine are transferred directly to the foundations. This prevents bending stresses in the housing and guarantees excellent tooth meshing even at maximum load.

Advantages

Efficiency

Optimized efficiency is achieved through economical gearing and low-friction bearings.

Reliability

A fail-safe lubrication system mounted on the gear unit itself ensures maximum operating reliability.

Adaptability

Our tried-and-tested design can be adapted to existing systems as required. This means that gear systems can be supplied with the same connections without the need for further structural modifica-tions.

Fast maintenance

The patented Eisenbeiss oil extraction system enables quick oil changes and minimizes downtime.

Applications

Hydropower
