Gear solutions for e-mobility

Gear solutions for e-mobility

New drive technologies in electric mobility are changing the requirements for gears and therefore also for the quality of the tooth flank surfaces. Manufacturers of gears have to adapt their manufacturing process accordingly. It’s good to be able to rely on a technology partner with expertise covering the entire range of production processes and technologies, which enables them to find suitable solutions even for special challenges.

Two become one

Liebherr-Verzahntechnik GmbH has refined its inspection software for gears and combined two steps into one: Chamfer measurement is now integrated into gear measurement. Initial default evaluation ranges ensure process reliability and maximum precision of the measurement results. In addition, the simplified data input and improved layout representation of the measuring protocol ensure usability.

Innovative automation solutions for e-mobility

In the course of the mobility transition, electric and hybrid drives will gradually replace the traditional combustion engine. The battery is a key element in electrification: More and more manufacturers are starting their own production of battery systems and are looking for suitable solutions to do so. Liebherr has looked into the processes extensively and offers system-capable, modular concepts for the automated assembly of battery packs.

Design award for LHStation and LHMobile

Design award for LHStation and LHMobile

Award for Liebherr-Verzahntechnik GmbH: The operating concept of LHStation and LHMobile won over the international jury in the “User Experience (UX)” category at the iF Design Awards 2021. Having nearly 10,000 entries from 52 countries to choose from, the jurors awarded this sought-after hallmark of excellence.

From a pencil sketch to high-tech automation

From a pencil sketch to high-tech automation

Hetec GmbH, the Hessian machining technology specialist and supplier for tool, mold, and machine construction, has automated its production using the pallet handling system PHS 1500 Allround. The company almost exclusively manufactures individual parts and small series with long spindle running times and does not seem like a typical automation customer at first glance. Nonetheless, a flexible automation system was the right solution. In this case, the secret to the system’s success is its integration into a well-thought-out system layout with three identical Grob G751 5-axis machining centers and the powerful Procam master computer. This combination enables the company to achieve optimal machining flexibility.

Gear skiving tools: a question of trust

Gear skiving tools: a question of trust

Gear skiving is considerably more productive than gear shaping and more flexible than broaching, but it also has its pitfalls. Minimal errors in tool design can be decisive for the success or failure of the manufacturing process. Comprehensive competence is required here, so that the user can be confident that his processes will work and that highest-quality components will be produced.

Liebherr Academy goes digital

Everyone's talking about digital learning – Liebherr shows how it’s done: Training courses on all topics connected with gear technology are now taking place in the form of interactive Live Online Training. Participants can tune in from anywhere and can also be trained virtually on the modern, fully equipped machines in Liebherr’s new Machine Training Center (MTC) if required. The new training catalog provides a comprehensive overview of all the training courses offered.

CNC chamfering with ChamferCut or FlexChamfer

CNC chamfering with ChamferCut or FlexChamfer

Chamfering gears prevents the edges of the teeth from becoming brittle during heat treatment and reduces transportation and installation damage. Multiple processes can be chosen for this.

Bin picking made easy

“Bin picking” is among the most difficult disciplines in automation. Adjusting the parameters for reliable recognition and gripping of complex objects is demanding and requires expertise. LHRobotics.Vision, a software by Liebherr-Verzahntechnik GmbH from Kempten, now makes bin picking much easier for users through Artificial Intelligence (AI).

Making mistakes is not an option

Making mistakes is not an option

For the serial production of planet carriers for gearboxes for commercial vehicles, the American gearbox manufacturer Allison Transmission has shifted to the gear skiving method. With Skiving³, Liebherr was able to implement several special requests within a short time due to good coordination between machine, tool and technology, significantly increasing the tool life and productivity.

Girls and technology – that’s a match!

Girls and technology – that’s a match!

Even though the proportion of women in technical professions is increasing, they are still under-represented in many companies. That’s not the case within Liebherr: for over 30 years, the company has been cooperating with the Maria Ward girls’ secondary school in Kempten. The vocational orientation project “MuT – Mädchen und Technik [Girls and Technology]” aims to increase interest of young women in technical professions at an early stage. We discussed this project from different perspectives.

SECLA – one for (almost) all

SECLA – one for (almost) all

Easy operation combined with maximum flexibility and short setup times – these are the features of the clamping arbor SECLA, which Liebherr has been successfully using in its own gear cutting machines for many years. Anyone who buys a SECLA from Liebherr also benefits from the company being a solution provider: from manufacturing to after-sales service, Liebherr offers everything from one source.

Liebherr automates the assembly of pluggable module connectors

Plug connections for electrical contacting of modules in the battery pack offer several advantages. However, until now it was only possible to assemble them manually – an obstacle for large batch sizes. Liebherr, together with KOSTAL Kontakt Systeme GmbH, has developed an innovative solution for the automation of the plugging process.

Liebherr is now offering tool grinding machines made by Seiwa, in order to expand the product portfolio for customers.

Automated line inputs and outputs

Automated line inputs and outputs

Due to the electrification of automotive fleets, there is no doubt among experts that growth in combustion technology will come to a halt. This will result in increased cost pressure on the current production capacities. A simple retrofitting solution by Liebherr for automated raw part input and finished part removal helps to make full use of productivity reserves.

From gear cutting to complete machining

From gear cutting to complete machining

Conventional turning and milling machines can perform gear cutting, albeit with limited productivity and accuracy. But are gear cutting machines also able to turn and mill? With Liebherr machines, upstream and downstream processes can be integrated. The LHGearTec programming and user interface, together with the Siemens control system, enables a continuous simulation and programming of all machining steps.
