The enclosed pitch curve of logarithmic spiral of non-circular gear tooth profile is generated in CAXA via the gear meshing theory and the conversion method of tooth profile for the enclosed pitch curve of non-circular gear tooth profile generation problems

then its three dimensional model is got in Pro/E.According to the tooth profile

some characteristics of the non-circular gear tooth profile could be analyzed which would be help for designing and investigation of the enclosed pitch curve of logarithmic spiral of non-circular gear tooth profile.
