Introduction of a new bevel gear measurement standard

Since many years bevel gear metrologists have sought for convenient bevel gear measurement standards to ensure traceability for those measurements for a reliable determination of the geometrical gear properties. ecently the PTB and the University of Bremen published a new patent for a bevel gear measurement standard. One standard body together with an appropriate software enables the calculation of various bevel gear look-like datasets. This feature significantly differs from cylindrical gear measurement standards, where one standard is assigned to one specific gear parameter set. This paper describes the concept, which offers an unusual flexibility. Initial results will be presented.
