Short summary
A nonlinear dynamic model of the noncircular face gear (NFG) was established. A semi-analytical approach, based on HBM and discrete Fourier transformation, is utilized to obtain the periodic responses. The results show that an increase in the eccentric ratio, input velocity and error amplitude will cause the non-rattle, unilateral rattle and bilateral rattle state in succession, and a jump phenomenon will appear when the state of the gears is transformed from unilateral to bilateral rattle.
