The picture shows 3D digital model of real gear in the mesh with digital master pinion. The data for the gear were taken on CMM from real gears. A computer program does all of composite gear inspection. PC based software uses CMM data to build digital gear models. It meshes gears, applies loading, calculates contact pattern, contact pass and transmission error.
Special software makes also vibration and noise analyses.
Finally it evaluates the quality of the mesh. The computer program rotates digital models of real gears as well as the real gear with a digital master. The all of inspection is happening inside a PC with no human interaction. Computer simulated mesh uses digitized surfaces. It calculates contact mapping with highest accuracy inside PC without any mechanical devices.
