DESIGN AND ANALYSIS OF PRODUCT-INTEGRATED GUIDE MECHANISM DRIVEN BY A NON-CIRCULAR GEAR

초록

For the purpose of optimizing the motion characteristics of the guide bar mechanism and enable the guide bar to perform uniform-speed reciprocating motion within a certain stroke range, a guide mechanism driven by non-circular gear is proposed. The transmission ratio of non-circular gear is constructed by the Fourier series equation. In order to facilitate the control of the transmission ratio of non-circular gear train, a method of designing non-circular gear train by constructing the transmission ratio equation using Fourier series equations is proposed. By combining Fourier series equations with non-circular gear transmission characteristics, a transmission ratio equation is constructed using Fourier series equations. Based on gear transmission characteristics, the pitch curve equations and transmission characteristic equations of driving and driven non-circular gears are constructed. For the sake of facilitating the selection of various design parameters, the effects of Fourier parameters and on the transmission ratio curve are analyzed. The guide mechanism can achieve an approximately constant speed motion law, verifying the feasibility of the non-circular gear constructed by the Fourier series equation of the transmission ratio. © 2025, Politechnica University of Bucharest.
