Optimum profile modifications for the minimization of dynamic transmission error

Robust design of vibro-impacting geared systems with uncertain tooth profile modifications via bifurcation tracking

“…Such modifications consist in an intentional removal of material from the tooth flanks so that the tooth profile differs from the theoretical perfect involute. Their effect on both the static and dynamic responses of geared systems are well known [14,20,30,19]. Most studies aim at minimizing the fluctuations of the transmission error to mitigate the dynamic response.…”

“…This is traditionally carried out by optimizing the tooth profile modifications through static computations [36,3,5,12]. Very few studies carry out dynamic analyses to define the best TPM, which often lead to different optimal solutions [24,10,30]. Such works try to minimize the peak-to-peak (𝐷𝑇𝐸 𝑃 𝑃 ) or the the root mean square values (𝐷𝑇𝐸 𝑅𝑀𝑆 ) of the dynamic transmission error.…”

Mesh stiffness calculation of helical gears with profile modification

“…Profile modification causes a lot of changes to gear pairs, such as engagement situation [1], tooth stress [2], and transmission error [2–4]. Researchers conducted many studies to figure out the influence of profile modification on gear characteristics.…”

“…Ozturk et al . [3] studied the dynamic transmission error and loaded static transmission error of a spur gear pair with profile modification using different models. The result showed that profile modification can be used to reduce dynamic transmission error.…”
