Gear technology and automation systems

Evotion 2021 | Magazine

The digital transformation, with its opportunities and risks, is a ubiquitous topic which is also being intensively addressed by Liebherr-Verzahntechnik GmbH. Michael Messer and Peter Wiedemann, General Managers for Production and Sales, view digitalization as a strategic challenge which must be implemented with sense of proportion and with a focus on customer benefit.

“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).

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.

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.

Mastering challenges together with the customer

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.

Chamfer measurement integrated into gear measurement

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.

Liebherr’s used equipment program goes international

The Reman used equipment program provides a second lease of life for older, high-quality machines. Since 2016, older machines have been refurbished at locations in Germany and the USA. Now the Reman program is also being launched at the Liebherr site in Brazil.

Distinguished in the “User Experience” category

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.

PHS 1500 Allround enables flexible individual part manufacturing

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.

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.

The ideal process for every need

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.
