Project planning

Thanks to their remarkable material features, girth gears made of ADI** can have less than half the weight of girth gears made of conventional materials that offer the same performance and safety. Project planning for girth gears by SEW-EURODRIVE is therefore an important requirement for creating customer benefits. The high degree of segmentation ensures that individual customer requirements can be met in an ideal way.

Applications

Example: mill / application size examples

– Power rating: up to approx. 15 MW

– Diameter: up to approx. 16 m

– Assembly: flange

– Speed of rotation: high (10 to 20 min-1)

Example: rotary kiln / application size examples

– Power rating: up to approx. 1 MW

– Diameter: up to approx. 9 m

– Assembly: leaf springs

– Speed of rotation: low (1 to 2 min-1)

Possible scope of delivery
