Gear Seminar in Brazil

In November 2024 Liebherr Brasil LTDA held one of its renowned Gear Seminars on gear technology in Guaratinguetá, Brazil. Industry experts were in the spotlight as their presentations focused on grinding, soft machining and measuring technologies. The program provided the wide range of participants with well-grounded technical knowledge and practical know-how, and showcased the expertise and services available at the Brazilian site. The accompanying program offered space for knowledge sharing and direct networking.

01Perfectly combined, highly versatile automation
Liebherr-Verzahntechnik GmbH has expanded and increased the adaptability of its production of sophisticated machined parts for Airbus Aerostructures with an intelligent automation concept. At the Varel site in northern Germany, two pallet handling systems (PHS), a robot cell and a tool handling system (THS) work together seamlessly to supply three machining centers and other connected system components with the parts they need at all times.

03Gear cutting and grinding from a single source
Liebherr-Verzahntechnik GmbH is continuing the systematic development of its platform strategy with the redesign of its machine platform for workpieces up to two metres in diameter. The new series encompasses all relevant gear technologies and is aimed at manufacturers of large gears, particularly in the mechanical engineering, marine propulsion, construction machinery and wind power industries. The lineup begins with hobbing and profile grinding machines designed for this size range – making it possible, for the first time, to perform precision hard machining on large workpieces.

04Rotary loading system (RLS) enhanced
Liebherr-Verzahntechnik GmbH have revised and further developed their rotary loading system (RLS) for automated and order-specific machine loading. Offering an additional load category for transportation weights up to 2,000 kilograms, greater storage density and wider interference diameters, the automation specialist is able to meet current manufacturing requirements. The new version will be presented at EMO 2025 in Hanover (Germany).

Rooted in all company departments

Liebherr combines sustainability and quality

Sustainability at Liebherr-Verzahntechnik GmbH is firmly rooted in all processes. Policies to conserve resources, increase energy efficiency and boost the circular economy are interconnected and incorporated directly into the products.

Monitoring the energy consumption of machines and workpieces

LHEnergyInfo: Quantifying sustainability

The new LHEnergyInfo app from Liebherr-Verzahntechnik GmbH measures and displays energy consumption in production in detail and in real time. As an integral part of the LHWebPlatform, it marks another step forward in the company‘s digitalization strategy.

Liebherr apprentices show their commitment to the Allgäu protective forest

6,000 trees for a training that prioritizes sustainability

Sustainability has long played an important role at Liebherr-Verzahntechnik GmbH – and that is also true for the training program. Since 2011, trainees have been working with the Kempten Office for Food, Agriculture, and Forestry to support the reforestation of the protective forest in the Allgäu region. Head of Training Matthias Fendt and trainees Felix Martin and Lukas Mittermayer report on last year‘s campaign.

Interdisciplinary training project in automation

Apprentices build mini gantry loader all by themselves

As part of an interdisciplinary training project, apprentices at Liebherr- Verzahntechnik GmbH have single-handedly designed, built and programmed a small-scale gantry loader. The aim of the task was to create a functional model, which replicated real processes in automation systems and could also be used as a practical learning object and for demonstrations. This was largely achieved by a project team of apprentices and dual-program students working autonomously.

Efficiency gains in twist-free generating grinding

Cost-effective optimization of tooth flanks

By advancing twist-free generating grinding, Liebherr-Verzahntechnik GmbH is elevating efficiency and quality in hard-fine machining to the next level. The machining times when using dressable grinding worms have been reduced to almost the same level as conventional methods – even with asymmetrical gear teeth. At the same time, optimized shift methods enable fine grinding or polishing to be integrated into a single machining step.

Hard-fine machining I – a cost effective process for internal gears and splines

Hard skiving: An alternative to grinding or honing

The hard skiving process opens up new possibilities in hard-fine machining internal gears and splines, which, when processes like grinding or honing are used, are difficult, unproductive or impossible to achieve. It can even out hardening distortion in a targeted fashion, stands out for its high flexibility, long tool life and economic efficiency, and can be used by simply changing the tool on the Liebherr-Verzahntechnik GmbH gear skiving machines.

Ilmberger expands its production with the LC 400 M gear hobbing machine

Powerful machine, powerful partners

Ilmberger Maschinen- und Zahnradfabrik GmbH has boosted its capacity for manufacturing cylindrical gears up to 400 millimeters in diameter by investing in the Liebherr LC 400 M gear hobbing machine. This efficient, compact, and adaptable solution perfectly aligns with the company‘s long-term customer commitments. And they were impressed not only by the technology, but also by Liebherr’s communication and service across the board.
