Advantages
- Modular construction system = Multi-purpose use of the housings and internal components
- Optimum load distribution between the planetary gears, among other things owing to high manufacturing accuracy and Finite-Element-calculation method (FEM calculation) of the planetary carrier
- Three or four planetary gears
Designs
- Output shaft as hollow or solid shaft
- Hollow shaft for shrink disk or with involute splines
- Solid shaft with parallel key or involute splines
- Input shaft with parallel key
- Input and output shaft sealed by means of radial shaft seals; can be combined with primary refillable labyrinth
- Input shaft with reinforced bearing
- Bearing of main planetary gear stage in standard or reinforced design
- Output can be combined with a short or long drive shaft and mounted pinion for use as gear unit in a slewing gear drive
Examples of Application
- Roller press drives
- Slewing gear drives
- Bucket wheel drives
- Apron conveyor drives
- Separator drives
- Agitator drives
- Travelling gear drives
- Steel band rolling mill drives
- Rotary kiln drive
