Vertical Spur Gear Systems for Kaplan open-flume Turbines
This gear concept is especially engineered to fully meet the tough requirements of vertical water turbines. For example, the turbine shaft is hollow-bored so that the rotor blades can be adjusted from above using the gear system. The bell is of massive design with suitable fins and is attached directly to the housing. As a result, the weight of the generator is supported securely and the risk of critical vibration is minimized. A special wear-free seal system on the input shaft side prevents any lubricant from escaping from the gear system.

Advantages
Efficiency
Optimized efficiency is achieved through economical gearing and low-friction bearings.
Reliability
A fail-safe lubrication system, which is built directly on the transmission, ensures maximum opera-tional safety.
Adaptability
The tried-and-tested design can be adapted to existing machinery, allowing new gear systems to be supplied with the same connections without the need for further structural modifications.
Fast maintenance
The patented Eisenbeiss oil extraction system enables quick oil changes and minimizes downtime.
