Compound motion characteristics analysis of eccentric herringbone curve-face gear pair

다국어 초록 (Multilingual Abstract)

To simplify compound gear transmission, this paper proposed a novel compound motion mechanism with an eccentric herringbone curve-face gear-pair, which combines a rotation motion and a linear motion to simplify complex mechanical transmissions. A compound transmission model of the pair was established based on the motion principle of the constant-diameter cam. Then we analyzed the impacts of variable eccentric distances on the axial displacement and axial forces of the non-circular herringbone gear. By utilizing SolidWorks and automatic dynamic analysis of mechanical systems, ADAMS, a simulation model for simulating the compound motion of the gear pair, was provided. Experiments were carried out by dividing the gear pair into two eccentric helical curve-face gear with opposite hands. The results implied that maximum axial displacement deviations from the experiment and simulation model are 1.8 % and 5.7 %, compared to the theoretical value, which verified the accuracy of the theoretical analysis.
