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.

Gear skiving used to be a gear cutting method that was difficult to control due to its complex kinematics, but it now offers a genuine alternative to shaping or broaching. The synergy between machines, tools and processes provided by Liebherr-Verzahntechnik GmbH’s Skiving³ technology package makes it possible to efficiently and flexibly machine an extremely wide variety of workpieces, including in small batch sizes. Skiving³ therefore crucially boosts productivity, quality and cost-effectiveness levels not just in series production, but in contract gear manufacturing as well.

Julia Stachel and Laura Scheiber completed their training as industrial mechanics at Liebherr-Verzahntechnik GmbH at the beginning of 2024. During their training period, they spent four weeks at the Liebherr plant in Yongchuan, China in August 2023. Here they explain what made them choose China, their experience there and what it is like to suddenly have lots of people wanting to take a photo with you!

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.

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.

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.

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.

Liebherr has been offering specialist seminars for the gearing industry all over the world for over 20 years. The gear seminars are designed as a learning and networking platform for users, where Liebherr experts and speakers from universities and from the industry discuss practical topics and specific issues relating to gear technology. At the same time, they offer participants the opportunity to share their experiences.
