FLENDER Planetary gear unit series for horizontal and vertical installation
This series includes more than 27 sizes. The gear units comprise two or three planetary gear stages which can be combined with different primary gear stages. Primary gear stages can either be helical or bevel gear stages or a combination of bevel and helical gear stage.
Operating range
Feature | Values | Unit |
|---|
Power rating | 30 up to 13,000 | kW |

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
