“…Additionally, there is potential to enhance fidelity of the simulation by considering more complex curves beyond simple sine shapes and defining different deviations across the teeth to better reflect real-world conditions. This may also help to improve dynamic models (Otipka et al, 2019) and (Prokop and Řehák, 2017) of geared transmission systems by providing more realistic transmission error waveforms, considering inevitable machining errors, as the input.…”

Transmission error (TE), a parameter influencing gears vibration and subsequent noise, is a subject addressed in many papers. However, most researchers consider ideal or modified involute while neglecting machining errors. This case study extends the author's previous work (Czakó et al., 2020) by incorporating tooth profile errors and investigating their impact on static transmission error (STE). Parametric geometry of 2D spur gears, including sine-shaped involute profiles, was generated directly within the Ansys Mechanical environment using APDL (Ansys Parametric Design Language), where all finite element analyses (FEA) were conducted. Various amplitudes corresponding to ISO 1328-1 accuracy grades 1-8, and wavelengths of sine functions modulated onto involutes, were simulated and compared in terms of resulting STE. The results underscore the importance of including profile deviations in models, mainly those common in industry, as they significantly influence transmission error.
