Performance analysis of generated hypoid gear based on measured tooth flank form data

• A performance analysis method for generated face mill hypoid gears is developed.
• The tooth flank form of the generated face mill hypoid gear sets is measured.
• Performance of the gear sets is analyzed using measured data.
• Transmission error of the gear sets is measured by experiment.
• Measured results of transmission error corroborate the analyzed results.

A method for predicting and analyzing the tooth contact pattern, vibration, and strength of a generated hypoid gear is needed to achieve a low-noise design and adequate quality control. However, it is not easy to analyze the performance of a generated hypoid gear because the tooth flank form is complicated and has a significant influence on the overall performance. In order to solve this problem, in this research, a method for analyzing one of the gear dynamics excitations and contact condition of a generated hypoid gear that considers the measured tooth flank form is proposed. The contact pattern and transmission error are measured experimentally and are compared with the analysis results. It is confirmed that the result from the proposed analysis method agrees with the experimental result.
