Title: Herbert Sommerfeld: Innovator in Steel Rolling Bearing Technology
Introduction
Herbert Sommerfeld is a notable inventor based in Ahrensburg, Germany. He has made significant contributions to the field of engineering, particularly in the production of steel rolling bearing rings. His innovative methods have paved the way for advancements in manufacturing processes.
Latest Patents
Sommerfeld holds a patent for a method for producing steel rolling bearing rings. This method involves starting from a hot-rolled tube with a spheroidized structure. The process includes hot-cutting rings of the same continuous length while supplying a lubricant. After cooling, these rings undergo further processing. The hot-cutting occurs at a temperature below the transformation temperature of the rolling bearing steel used but above 720°C. The subsequent cooling takes place in static air. The result is a green or soft ring of a rolling bearing with narrow tolerances achieved through an optimally timed multistage machining operation, primarily involving turning.
