Title: Innovations of Johannes Wozniak
Introduction
Johannes Wozniak is a notable inventor based in Lippstadt, Germany. He has made significant contributions to the field of engineering, particularly in the thermomechanical treatment of seamless rings and bearing rings for large roller bearings. With a total of 7 patents to his name, Wozniak's work has had a considerable impact on manufacturing processes.
Latest Patents
One of Wozniak's latest patents is a method for the thermomechanical treatment of seamless rings produced on radial-axial ring rolling machines. This innovative method involves inserting a ring blank into the ring rolling machine at temperatures ranging from 900°C to 1150°C. The rings are rolled to an outer diameter between 0.2 m and 10 m through a hot forming process. Following the rolling, the hot rings are quickly cooled down through a controlled process, ensuring they reach temperatures below 400°C without secondary heating. The device used in this process includes a dipping basin filled with cooling liquid and pressure nozzles for targeted application of the cooling liquid onto the ring surfaces. Additionally, Wozniak has developed a method for making a bearing ring for large roller bearings, which involves hardening the annular race by heating and quenching.
