The Evaluation of Form Deviations During Teeth Manufacturing of Gear Rings

The aim of research is to perform the analysis of geometrical form of internal and external teeth of gear rings where external teeth are involute splines. These gear rings are applied in aircraft engineering in planetary gear trains. The authors present a general manufacturing process of gear rings and the measurement results of form deviations. The analysis of manufacturing errors of gear rings is presented - starting with first manufacturing operations and ending with the final product. The influence of these errors on design features of the manufactured product is also shown.
