Bidirectional thermo-mechanical coupling in spur gears: Unveiling the nonlinear dynamics of tooth contact temperature

Key Points

• Tooth contact temperature is significantly influenced by thermo-mechanical coupling in spur gears.
• Observations indicate varying friction levels alter temperature dynamics during gear operation.
• Analyses reveal nonlinear behaviors associated with tooth interactions under different loading conditions.
• These findings may lead to enhanced efficiency and durability in gear system designs.
