| Abstract: | To address the issue of seedling precision affected by transmission errors resulting from tooth backlash in the seedling pickup process, this study presented a novel solution by introducing a design method for a noncircular superimposed gear (NCSG). The influence of the different numbers of NCSG slices on meshing line length and contact ratio was analyzed. The NCSG was manufactured using wire‐cutting technology, and a transmission ratio measurement experiment was performed. In comparison with theoretical data, simulated data, and experimental data, it was found that the three were basically consistent. Furthermore, the NCSG was applied in the seedling pickup mechanism of the planetary gear train. The observed seedling pickup trajectory matched the simulated trajectory. To validate the performance of the mechanism prototype, a seedling pickup experiment was conducted on the seedling pickup mechanism of the NCSG planetary gear train. The success rate of seedling pickup is over 93%, demonstrating the mechanism's effectiveness. [ABSTRACT FROM AUTHOR] |
