Gear technology and automation systems

Magazine 2020

Gear skiving is over 100 years old and has recently been experiencing a renaissance as a flexible and economical alternative to other gear cutting methods. However, this complex process frequently presents great challenges to users. In addition to Skiving3, a “complete package” consisting of machine, tool and technology, Liebherr now also offers skiving tools for suppliers and contract gear manufacturers – and the appropriate consultation, if desired.

In August 2019, trainees Fabian Altenried and Julia Fetzer participated in the Liebherr Summer Program at Liebherr Gear Technology Inc. / Liebherr Automation Systems Co. (LGT / LAU) in Saline, near Detroit. There, they ran the PLC programming course for pupils of the robotics course from the local high school, which was offered for the first time, and got to know the work routine at the Liebherr site. Fabian reports on his experience here:

Liebherr is embracing technological change towards alternative drives and has developed a modular automation system solution for the assembly of battery packs for electric cars – from small batch manufacturing to fully automated mass production. Advantages: Liebherr automation is system-compatible and offers process reliability, fast cycle times and flexibility.

Until now, Liebherr has provided Bin Picking solutions with software supplied by a partner. Now the company offers its exclusive software package with new features that can also be integrated into systems from other manufacturers. Liebherr’s combined expertise in software development and industrial application also makes LHRobotics an interesting product for integrators.

How can we ensure maximum manufacturing productivity? What is the best automation system for our wide variety of parts? Which partner can reliably put our plans and requirements into practice? These are the kinds of questions that every manufacturing company aiming to increase its productivity has to ask. Kordel Antriebstechnik GmbH, based in the Westphalian town of Dülmen, found the right solution for its gearbox production with a pallet handling system from Liebherr.

Close to production, with high cleanliness and air conditioning standards: The two new measuring rooms of Liebherr-Verzahntechnik GmbH at the Ettlingen site are used for quality control during the production of Liebherr gear cutting tools and for contract manufacturing.

A visit to the HMC Gears plant in Indiana kicked off an extensive project which resulted in the creation of a unique solution for exceptional demands: With the LC 4000, Liebherr forges new paths in large-scale gear cutting production and unites diverse machining methods in one highly efficient machine for the American gear specialist.

Clamping units for gears with short delivery times at low costs – due to the high level of individualization of clamping devices, these demands were often diffi cult to reconcile. That’s now a thing of the past. The segment clamping arbor SECLA from Liebherr is an innovative, inexpensive standard solution with short delivery times for a maximum application range in gear manufacturing machining.

Karl-Heinz Klöble is responsible for putting large gear cutting machines into service in China. We spoke to him about his experiences there and what fascinates and motivates him in his unusual job – and why he’s too busy to retire yet.

What does the name LHOpenConnect stand for? How can an open data structure help the user? Which software services does Liebherr-Verzahntechnik GmbH offer? Over the past few years, the company has gradually built up an application architecture that focuses not only on the machine, but on the entire process, which means it can support production in many different ways. Thanks to its modular structure, customers can select the tools which best complement their own specific production environment.
