WebMar 11, 2024 · The extended tooth contact is the phenomenon of theoretical separation teeth contact under force. Due to the flexibility of the gear, the deformation of the gear pair increases as the applied force increases, resulting in earlier contact during engagement, and later separation during disengagement. Therefore, the load-dependent ETC … WebApr 2, 2009 · But in actual practice, extended tooth contact (ETC) occurs due to gear tooth deflection under load. Considering the effect of ETC, the mesh stiffness in the pre-mature and post-mature contact regions is gradually rather than abruptly varying with time, which would influence the parametric stability of the geared system significantly. ... creality vip mall https://balbusse.com
