Scanning Measurement and Evaluation of Gear Tooth Root and Bottom Profiles

Tooth root and bottom profiles of cylindrical gears affect bending fatigue life, but it is hard to measure them with conventional gear measuring machines (GMMs), because GMMs are normally customized to measure only gear working flanks. We try to develop a new type of GMM by installing an extra 3D sc...

Summary:Tooth root and bottom profiles of cylindrical gears affect bending fatigue life, but it is hard to measure them with conventional gear measuring machines (GMMs), because GMMs are normally customized to measure only gear working flanks. We try to develop a new type of GMM by installing an extra 3D scanning probe and control software to measure tooth root and bottom profiles. To be able to measure in various directions, a 3D scanning probe instead of a single directional scanning probe has been attached to a GMM developed, which has servo and linear driving motors generating less heat. Discrete point measurement and scanning measurement of tooth root and bottom profiles of cylindrical gears is described and evaluation of measured results is discussed.
