Standard gear units

FLENDER gear units are used in a wide range of industries, offering optimum performance and high configuration flexibility.

Reliable gear units

Modern drive systems must combine reliability, resilience and maximum efficiency to ensure high plant availability and minimise operating costs. FLENDER gear units are synonymous with durability and efficiency, and the modular design allows precise adaptation to the specific requirements of each industrial application.

An aerator is an impeller in the biological part of a wastewater treatment plant. It agitates the surface of the water, enriching it with oxygen, which activates bacteria, enabling the removal of biodegradable components from the wastewater.

The rotor is mounted on the gear unit output shaft, which is extended vertically downwards at some distance from the gear unit itself. In order to prevent contamination of the treated water with gear oil, FLENDER gear units have been designed with an output shaft equipped with an oil retaining tube and a shaft seal, which are not in contact with the shaft and are not subject to wear. The axial and lateral forces resulting from the process are absorbed by the extremely robust output shafts and output bearings.

The drive units used in paper production and finishing plants vary widely in type and size. In most cases, this depends not only on the size of the plant, but above all on the type of paper. More than 1,300 complete paper machine drives installed worldwide.

Specification

Application

from mechanical pulp production, pulp production and recovered paper recycling to drying sections, glazing rolls, M.G. cylinders, coating machines, calenders and waste water treatment plants

Specification

Variants

single pinion drives, central drives, ring wheel load sharing gear units

Application

milling mills, with power requirements of up to 30 MW, are among the largest driven machines. They grind minerals (ores or cement clinker) by impact and friction until the material is pulverised

tube mills, which can be up to 15 m in diameter and up to 20 m long, are installed horizontally

Product range

FLENDER gear units are drive solutions which, thanks to their design, can be adapted to the specific requirements of various industries. Optimised tooth geometry and a modular design ensure high efficiency and durability, while various mounting options allow flexible integration into industrial systems.

The range includes helical and helical-bevel gear units with high efficiency and low energy losses, ideal for conveyor systems, mills and crushers. Specialised models for aerators and lifting mechanisms are distinguished by robust shafts and durable seals.

For industries such as paper, cement or mining, longer-life gear units designed for harsh environments are available. Their robust design and mounting flexibility allow efficient integration into drive systems.

FAQ

We use advanced diagnostic techniques such as:
• Vibration analysis,
• Thermal imaging,
• Oil analysis,
• Acoustic diagnostics.

Each of these methods allows for the technical condition of the gear unit to be accurately assessed and for appropriate remedial action to be proposed.

We have access to full documentation and are able to supply both spare parts and complete replacement gear units for older FLENDER models. We also offer verification in the case of other manufacturers.
