Method and the device for non-destructive measurement of a carburized layer thickness and surface life of the gear teeth

摘要

how is such that the length of a toothed wheel space between two adjacent teeth (so-called.notch) is measured in one cycle measuring layer thickness at the bottom of the wru0119bu (b), the layer thickness on the surface side of one tooth (a) and surface hardness on the surface side (c) of the second tooth pointing to test points, perpendicular to the surface of the test, a set of three eh sensor measuring different frequency excitation.one of which is measured on the surface of the layer thickness nawu0119glanej lateral tooth, the second layer thickness at the bottom of the nawu0119glanej wru0119bu and third hardness on lateral tooth.the device is monolityczna housing reflects the geometry considered toothed wheel, in particular, the space between two adjacent teeth (wru0119bu) in which is placed a single eddy current sensors with different excitation frequencies.with each sensor is positioned perpendicular to the surface of the casting corresponding to the surface on the cog section considered by this sensor.
