WZL Gear Research Circle


The WZL Gear Research Circle is an association of the leading companies in powertrain technology. Since 1956, we are working together with our members to develop new technologies within the framework of collaborative research to establish them at an early stage in industrial practice in order to secure a technological lead for our member companies and, thus, a leading position in international competition.

The WZL Gear Research Circle is the only one of its kind in Europe to conduct intensive research work in the fields of powertrain and gear design, gear production, gear measuring technology and the investigation of the operational behavior of powertrains and gears. A special characteristic of this work is the holistic approach to gear and powertrain technology, from design, manufacturing and measurement technology to application behavior. The consistent treatment of basic and practice-oriented tasks throughout the entire development and process chain in a research institution is unique in this form.
By taking into account all these relevant areas of transmission technology, synergy effects can be exploited and integrated solutions to problems can be offered, which are strongly tailored to the needs of the member companies of the transmission group. Together with our partners, we develop bilateral solutions for specific tasks. At the same time, we carry out research projects with industry associations (VDW/FWF, FVA, AGMA,...). Further research topics are dealt with within the framework of publicly funded projects. These include, for example, research projects of the DFG, BMBF, AiF, BriteEuram, Craft, etc. In addition, the financial resources of the transmission group allow us to address interesting topics at short notice.

A permanently installed platform for a lively exchange of experiences and a close cooperation of the WZL Gear Research Circle is the annual Gear Conference in Aachen. On two days, the latest results from the field of transmission technology will be presented to the member companies by the employees of the WZL gear department. The presentations will be rounded off by panel discussions and specialist lectures, in which current drive technology issues will be discussed from the point of view of industrial users, with the inclusion of the members of the gear group.
