多杆分插机构的工作效率低，传动比的具体变化规律（传动比曲线有两次不等幅波动），其在蔬菜钵苗移植中需要，难以使用具有非圆齿轮和单行星架的行星齿轮系来实现。为了解决这个问题，我们提出了一种非圆齿轮副，它包括一个不完整的非圆齿轮，齿条，部分非圆齿轮，椭圆齿轮。分析了TUA齿轮副的结构特点和工作原理。根据非圆TUA齿轮节曲线的角位移关系，推导出相应的节曲线方程。分析了圆心角α和偏心距k对TUA齿轮副节曲线形状、角位移和传动比的影响。根据设计要求，将TUA齿轮副应用于蔬菜取苗机构。最后，通过SPM试验验证了新型非圆TUA齿轮传动机构的可行性。
The operation effectiveness of multi-bar transplanting mechanisms is low, and the specific changing law of the transmission ratio (the curve of the transmission ratio has twice unequal amplitude [TUA] fluctuation.), which is needed in vegetable pot seedling transplanting, is difficult to fulfill using a planetary gear train with noncircular gears and a single-planet carrier. To address this problem, we propose a noncircular gear pair that comprises an incomplete noncircular gear, rack, partial noncircular gear, and elliptical gear. The structural characteristics and the working principle of the TUA gear pair were analyzed. The pitch curve equation of the noncircular TUA gears was derived from the relationship of the angular displacement of the corresponding pitch curves. The influence of central angle α and eccentricity k on the shape of the pitch curve, angular displacement, and transmission ratio of the TUA gear pair was analyzed. The TUA gear pair was applied to a proposed vegetable seedling pickup mechanism (SPM) considering the design requirements. Finally, the feasibility of the new noncircular TUA gear transmission mechanism was verified by an SPM test.
