Siemens Flender HD - Flender is a leading international manufacturer of mechanical and electrical components for power transmission equipment with locations in Bocholt Germany and Elgin IL USA. They offer a diversified product ranging from individual components and also complete drive system for your Marine Gear and Vertical Mill Drives for the Cement, Coal and Minerals and Mining Applications.
Heavy Duty Vertical Mill Drives
- Made out of nodular graphite cast iron (GGG)
- Stiffnees and stress were optimized by finite element calculations
- Standardized with variable cast patterns (two gear unit size - one housing)
- Identical Planetary stages are used for the Flender Vertical Mill Gear units type KMPP:
- Higher availability of raw materials
- Identical parts will be manufactured in bigger lots
- Hydrodynamic Thrust Bearing
- Hydrostatic Thrust Bearing
KMPP Advantages
- More compact and smaller in diameter
- Gearbox design complete with slide bearings
- High Input Speed => smaller Motor
- Coupling Seeve is very long => less relatively movement
- Cyndrical coupling sleeve removable from the top of the gearbox
- Adjustment of the bevel gear by wedge shoe from the outside
- Readjusted of the tooth contact pattern of the bevel gear with wedge shoe under the mill (from Flender Supervisor)
- Flange and planetary carrier in one-piece
- Outer Gearbox Diameter can be smaller
- Direct Pressure oil to each Bearing and Gears
- For bigger dimension, slide bearing can turn faster
- Slide bearing in the planetary stages improve an equal load distribution by the hydrodynamic lubricating film
- Damping - Not sensitive against shock loads
- Life time - no life time limitation
- Delivery time - complete repaired bearing time approx. 3 month
- Emergency repairing - normally emergency repairing is possible at side
Marine Gearboxes
- Power ranges from 1200 HP to 60,000 HP
- Transmission ratios from 1.5 to 12.1
- Propeller thrust bearings are built into the gearbox
- One motor or one engine drive
- Twin motor or twin engine drive
- Generator gearboxes
- Gearboxes for Dredgers
- Customized solutions
- One stop shop for motors, gearboxes, couplings and control systems
Jack-Up Gearboxes
- 440 KIP - P2PA 21 gearbox ABS approved and supplied
- 550 KIP – Under design
- 1000 KIP – P2PA 28 design complete
- Depending on market requirements smaller sizes can be developed
