Gear Tooth Contact Marking Measurement By Image Processing 852274
Tooth contact marking of gears is an important quality
characteristic that affects tooth strength and gear noise. Tooth
contact marking measurement is generally done by painting the tooth
surfaces of two meshed gears, rotating the gears and visually
observing contact marks. Since it requires much working hours and
experience to judge such a measurement, a method of measuring
contact tooth markers by image processing has been developed.
In this measurement method, the tooth surfaces of rotating gears
are continuously observed by a TV camera, and the images are stored
in an image memory device. Such quantities as the tooth surface
size and tooth surface brightness level are set as initial
settings, and the set values are compared with the observed images
by a microcomputer to give the results of the measurement.
