Wenzel GearTec GmbH, a successful manufacturer of gear inspection machines, has been part of Liebherr-Verzahntechnik GmbH since May 2019. The Karlsruhe-based company has specialised in the measurement of gears, gear cutting tools and other rotationally symmetrical workpieces since 2004 and has an innovative product range that perfectly complements Liebherr's own.
Half a century of Liebherr-Verzahntechnik GmbH means 50 years of commitment to the machinery and plant engineering industry. Gear technology originated in the technology of the revolving tower crane. Hans Liebherr wanted to buy a gear hobbing machine for gear manufacturing, but could not find what he wanted – so he simply built it himself. It’s a typical Liebherr story, since many sectors in the company group have emerged in this or in a similar way. Taking things into one’s own hands: an attitude that can still be found at Liebherr today.
Bauer Gear Motor operates two new LC 180 gear hobbing machines at its facility in Slovakia, producing gearing for all facilities. These machines are characterised by their operational versatility, given that they are used to produce around 180 different components in a very wide range of different sizes.
“The fire pump is the heart of every fire truck”, explains Michael Schöftner, Head of Mechanical Production at Rosenbauer International AG, the global leader for fire service equipment. The equipment has to withstand enormous loads in cases of operation. Rosenbauer relies on an automation solution for pump manufacturing from Liebherr. The rotary loading system RLS 800 from the Kempten-based automation experts has been deployed in Leonding near Linz for around two years now.
The demand for high quality gear teeth in areas such as electric mobility, for example, come with great challenges. Liebherr is working on the development of solutions for economic manufacturing
For the mobility of the future, we need solutions today. Sometimes this means starting from scratch. With a new production line, new processes and new machines.
The aircraft propulsion systems of today are wonders of technology. Since air travel is rapidly growing in demand around the world, the production technology employed until now needs to be modernised.
What challenges does Industry 4.0 present to companies and their apprentices? Liebherr is already working on the measures necessary for overcoming the technical obstacles of the future in order to train its own professionals.
It starts with a blank. But how does the workpiece get onto the line or into the machine? Depending on the state it is delivered in, this task can quickly become very complex. Reliable 3D object detection systems optically capture and evaluate data. Liebherr works with a variety of 3D vision systems to match the requirements and smoothly handles the supply of every randomly stored part with process precision.
Simply order from the catalogue and two days later the new shaping tool will arrive: Liebherr makes the process as straightforward as this for customers and offers a broad range of stock tools available for immediate delivery. New: Instead of cutting material ASP2030 with a titanium nitride (TIN) coating, stock tools are now made as standard from ASP2052 with Alcrona Pro.
The first LK 500 skiving machine is in use at the Italian gear specialists SIAP. An innovative investment that will increase both productivity and quality.
Liebherr has met the needs of automation customers with the PHS Allround: The compact class for universal users has been in great demand. Alongside the current PHS 1500 Allround version, Liebherr has announced two more sizes - the 800 and 3000.
