METHOD FOR QUANTITATIVELY DETERMINING THE SIZE OF A SOFT ZONE AREA OF A PARTIALLY HARDENED WORKPIECE

METHOD FOR QUANTITATIVELY DETERMINING THE SIZE OF A SOFT ZONE AREA OF A PARTIALLY HARDENED WORKPIECE

The bolt (1) used to hold a planet wheel in an epicyclic gear train has a hardened center section (2) and soft ends (3). The workpiece hardness measurement system uses a multi-frequency eddy current measuring coil (4) which is passed along length of the bolt. Differences in the eddy currents enable...

description The bolt (1) used to hold a planet wheel in an epicyclic gear train has a hardened center section (2) and soft ends (3). The workpiece hardness measurement system uses a multi-frequency eddy current measuring coil (4) which is passed along length of the bolt. Differences in the eddy currents enable it to detect and measure the lengths (b) of the soft ends of the bolt.
