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.

With the PHS 10000 Pro pallet handling system from Liebherr-Verzahntechnik GmbH, the machine tool manufacturer GROB in Mindelheim has automated its in-house production of machine components on two 4-axis machining centers and thus increased productivity by around 45%. The challenge here was not only to manage large parts weighing tons, but also a series of additional constraints that required highly individual solutions, as well as project planning where not a single day‘s work could be delayed.

Liebherr-Verzahntechnik GmbH now provides its customers with the most important drive and actuator data from a machine – its "digital fingerprint” – as a service to simplify and accelerate machine diagnostics. This makes condition monitoring easier and reduces maintenance costs.

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.

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.

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.

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.

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.
