Schaumburg, Illinois. For more than 50 years the annual WZL Gear Conference in Aachen, Germany, has been the basis for the exchange of experiences and close cooperation between the members of the WZL Gear Research Circle. The WZL Gear Conference takes place for two days which are exlusively devoted to the latest research on gear design, manufacturing, and testing. Seven years ago, WZL started to present exclusive content of the Aachen conference in the United States. This 4th conference is hosted by Reishauer and provides the opportunity for American companies to get in touch with WZL and learn about current research activities.
