The Swabian manufacturer of transmission and drivesolutionsSPN Schwaben Präzision Fritz Hopf GmbH manufactures gearboxes, gears, and drive systems according to individualcustomer requirements. The company uses various machinesLiebherr-Verzahntechnik GmbH and can therefore rely on innovativemachine and tool technology as well as reliable contacts.
Liebherr-Verzahntechnik GmbH is taking the plunge into artificial intelligence (AI) with its latest version of LHRobotics.Vision bin picking software. Filtering out irrelevant image data enables faster and more accurate detection of unsorted workpieces when removing them from containers.
In electric vehicles, the meshing of the gears can cause disruptive gearbox noise excitations. It is therefore becoming increasingly important for automotive manufacturers and suppliers of electric motors to identify and eliminate the causes of unwanted noise at an early stage. With the LHProcessMonitoring software, Liebherr-Verzahntechnik GmbH has developed a tool that detects deviations during gear production. This saves costs and reduces rejects – and is therefore also of interest to manufacturers of conventional gearboxes.
Pongi Gear Experts Co., Ltd. has represented Liebherr-Verzahntechnik GmbH in Taiwan for many years. In 2022, it incorporated the Kempten company‘s bin picking software into its portfolio and set up its own demonstration and training facility for intelligent automation. Potential customers can evaluate the smart and intuitive system on a fully equipped cell with a camera, robot and simulation tool.
Sustainability goals and increasing raw material prices are making the recycling of batteries from electric vehicles an increasingly pressing issue for the automotive industry. To recover the valuable raw materials and components from the battery packs, they must be disassembled and sorted at the end of their service life. Automated processes provide a basis for economic dismantling while minimizing the hazards to employees from high-voltage equipment. Liebherr-Verzahntechnik GmbH uses its tried and tested automation technology for this and is working with research and industry to develop scalable, flexible solutions for the automotive and recycling sectors.
PHS 1500 Allround increases productivity at Linde Hydraulics by 30%
For the manufacturing of valves and valve kits, Linde Hydraulics GmbH & Co. KG invested in a production plant at the Ballenstedt site with five 5-axis machining centers from Grob, which are interlinked via the PHS 1500 Allround pallet handling system from Liebherr-Verzahntechnik GmbH. This enabled the company to increase the output of this manufacturing line by 30%. The planning was quite a challenge: due to the high demand, not only did additional machines have to be integrated, but an alternative location for the plant in the historic production halls also had to be found during the project.
Assignments abroad for trainees
The opportunity to gain experience abroad and work in Europe, the USA or Asia has been an integral part of training at Liebherr-Verzahntechnik GmbH since 2000. After a temporary interruption due to Corona, the program is once again enjoying great popularity. The young people taking part in the assignment not only experience enriching stays abroad but are also well-prepared for international service assignments.
Detecting micro-deviations on gear geometries at an early stage to eliminate increased noise emissions
In electric vehicles, the meshing of the gears can cause disruptive gearbox noise excitations. It is therefore becoming increasingly important for automotive manufacturers and suppliers of electric motors to identify and eliminate the causes of unwanted noise at an early stage. With the LHProcessMonitoring software, Liebherr-Verzahntechnik GmbH has developed a tool that detects deviations during gear production.

The revised Liebherr gear shaping machine with new features
Gear shaping is a robust and universal process for manufacturing gears – due to the geometries of some gears, no other machining methods are capable of producing the teeth. In order to offer even more versatility in this area, Liebherr-Verzahntechnik GmbH has fundamentally revised and developed its LS 500 E gear shaping machine. A shaping head featuring an electronic helical guide and an interface for an optional chamfering device are now included as standard.
50 years of Liebherr Brazil
Liebherr Brasil Ltda is celebrating its 50th anniversary in 2024. Excavators, cranes, truck mixers and slewing bearings are just some of the products manufactured for the South American market at the site in Guaratinguetá, Brazil. The sales and service activities of the group are also gathered together here. Liebherr-Verzahntechnik GmbH also has 15 employees at the site.
High-precision measuring machines for small and large gears
The Liebherr WGT series of gear measuring machines are used in gear manufacturing for a wide range of industries: from the smallest aerospace applications to large gearbox components for wind turbines, tower cranes or commercial vehicles, where some of the gears weigh tons. With the optimized WGT 1200, Liebherr-Verzahntechnik GmbH provides high-precision measurement even for huge workpieces up to a diameter of 1400 mm and a weight of 5 tons.
Helping out the Slovenian automotive supplier KLS after the flood disaster
Following the flood disaster in Slovenia in August 2023, Liebherr-Verzahntechnik GmbH provided active assistance for the automotive supplier KLS d.o.o. With commitment, expertise and minimal bureaucracy, the team of engineers performed what seemed an impossible task in just 1,200 work-hours: all of the Slovenian company‘s gear cutting machines – initially thought to be damaged beyond repair – were back up and running before Christmas.
Recycling of high-voltage batteries used for electromobility
In 2023, Liebherr-Verzahntechnik GmbH was awarded the Best of Industry Award in the Robotics category. The company received the award for its solution for the automated disassembly of battery packs from electric vehicles.
