For the aerospace industry, high-precision roughness measurement of the surface quality of gear teeth is a key requirement for ensuring dimensional accuracy, wear resistance, and longevity. With its new development, Liebherr-Verzahntechnik GmbH enables roughness measurements on gears using a skid-type probe and a free-moving probe.
Skid probes use a skid as a reference level and measure the microprofile of the surface relative to this. "They are lightweight, easy to handle, and sufficient for many standard applications," said a company spokesperson. "However, for particularly demanding applications,Äîsuch as in aerospace application, and for polishing processes,Äîmore extensive values must be recorded."
The free-moving probe is fully mobile and, in addition to roughness, also detects other geometric features of the surface. Its mechanics are so lightweight and compact that it fits into small installation spaces and detects all relevant roughness characteristics.
,ÄúOur free-moving probe can be used from module 1.0 and in internal gears with diameters starting from 120 mm,,Äù explained Omar Sharif, Head of Measuring Technology.
Tooth and roughness measurements can be performed in a single set-up, with automatic probe change. The LHInspect software allows detailed configuration of the roughness measurement parameters and the roughness features to be examined.
