Gear Contour Analysis

Manufacturing of high precision gears requires stringent quality control, in order to obtain the best operational conditions and energy efficiency. Surface defects on the gears may lead to negative impact on the gear mesh quality. Moreover, during the service time, wear and tear takes places, creating surface defects such as dents and cracks in the gears that may result in decreased power transmission efficiency and potential mechanical failure. An accurate and quantifiable tool for surface inspection is in need. Unlike a touch probe technique, the Nanovea Profilometer performs 3D contour analysis of the sample without touching, making it possible to precisely scan samples with a complex shape, such as gears of different geometry.
