Purpose of the Study:

• To develop a methodology for generating precise gear models with an original, adjusted tooth profile.
• To analyze the contact pattern and stress distribution in gears with a modified circular-arc tooth profile based on Novikov engagement.
• To validate the numerical model through finite element method (FEM) analysis.

Main Methods:

• Solid modeling using enveloping generation and AutoCAD scripting for automated material removal simulation.
• Creation of gear models with a circular-arc tooth profile, adjusting parameters from Novikov engagement standards.
• Finite element method (FEM) analysis using ANSYS software to simulate loaded gearbox conditions.

Main Results:

• Precise gear models with an adjusted circular-arc tooth profile were successfully generated.
• Contact pattern analysis revealed the distribution of forces on the modified gear teeth.
• The stress state of the gear transmission was determined, highlighting the impact of the adjusted profile.

Conclusions:
