Advantages
Highly segmented girth gears, segments
1.
Easy casting
The design of the feeders and the use of heat sinks guarantee a seamless casting quality even
with critical segments
2.
Convenient handLing
-
The handling of the individual segments and component groups is simpli²ed both in the factory
and at the construction site
-
No need for special transportation arrangements: segmented girth gears can be transported in
standard containers
3.
Optimized quaLity assurance
- The minimized size brings also cost advantages when it comes to the scrapping of blanks
- Flawless blanks can be used without additional welding or oversizing
4.
Precise pitch accuracy
-
The segmented girth gears from SEW-EURODRIVE guarantee the initial pitch accuracy of ISO 8
(AGMA 9)
- Because of the high pitch accuracy, the vibrations of the girth gears are kept to a minimum
5.
Easy repLacement
If a segment is damaged, it can be exchanged without dismantling the whole ring
6.
Reduced weight
- ADI** has an over-average contact fatigue strength due to its cold work hardening Features
-
These features combined with an appropriate girth gear size enable a compact and lighter
design compared to the traditional solution
-
The low weight is important for the handling and the assembly of the girth gear as well as the
achievable circumferential velocity
7.
±ncreased service Life
With the correct dimensioning, load and lubrication, an ADI** girth gear is nearly wear-free
8.
Shorter deLivery time
The small segments allow for fast production and short delivery times
