Project drive technology
sector
Drive technology, renewable energies
Problem
In the low-temperature range in particular, problems were occurring with the sealing rings formerly used in solar parks.
project
Development of new shaft sealing rings for optimal material resilience even in an extended temperature range.
application
Use in solar parks with huge temperature differences and changes in weather.
requirement
Material needs to withstand the extended temperature range with 100% reliability. Test carried out solely using the lubricants provided by the customer.
result
- Development of new shaft sealing rings with an application-specific design with multiple sealing and dust lips
- The requirement to counteract possible dirt between the flange and the transmission is met not only thanks to a second radial dust lip, but primarily also thanks to an additional axial dust lip
advantage
Huge temperature range withstood with 100% reliability.
