| Zusammenfassung | Gear evaluation strategies for testing the surface geometry of involute gears arecommonly carried out according to the standard ISO1328-1 (Ref.1) and VDI/ VDE guidelines aiming for the determination of helix, profile (Ref.2) and pitchdeviations (Ref.3). These deviations refer to single helix, profile line, and pointwise inspections of specific gear teeth, which is sufficient in most cases and has been demonstrated by international intercomparisons (Refs.4, 5). The deviations on the gear flanks are caused by manufacturing defects due to various error sources. Therefore, identifying these error sources is essential for the improvement of manufacturing processes. Two different types of defects can occur during the manufacturing process (Refs. 6, 7). First, systematic defects caused by the positioning of the tool, tool wear, or other sources. This results in the same, reoccurring deviation on each tooth. Therefore, the associated systematic manufacturing defect can be specified, if only single teeth are tested. Second, individual defects caused by changing conditions during the manufacturing process like temperature gradients, tool vibrations, spindle positioning errors and other drifting effects. Individual manufacturing defects can occur on any tooth and can only be accurately evaluated if all teeth are tested (e.g. Ref. 7). In order to characterize different sources of defects properly, measurements should refer to a common reference coordinate system, and an error separation method has to be applied. However, error separation is most efficiently achieved when all measurements have taken place in the same reference coordinate system. A common reference system would also lead to a more accurate determination of the deviations. So far, this approach has not been established in gear metrology. As well as evaluation of profile, helix and pitch deviations, harmonic analysis of measured 2D trace data is routinely used by some industries to control gear noise (Refs. 8–10) and characterize machine tool performance (Refs. 11, 12). Evaluation of 3D surface measurement data has not been investigated. |
