一种新型类偏心圆非圆齿轮设计及其应用

为了克服偏心圆非圆齿轮传动能够满足的非匀速传动要求有限的缺陷，提出了一种新型类偏心圆非圆齿轮，为方便该类偏心圆非圆齿轮的计算，采用切线极坐标方式推导了其节曲线方程，同时建立了该类偏心圆非圆齿轮节曲线的凹凸性判断和弧长计算模型；编写了类偏心圆非圆齿轮辅助设计及运动仿真软件，对其传动特性进行了分析和总结。将该类偏心圆非圆齿轮用于驱动卧式枕形包装机横封机构，通过比较发现，该类偏心圆非圆齿轮比一般的偏心圆非圆齿轮能够更好地满足横封工艺要求。

Design and Applications of Generalized Eccentric Noncircular Gears

In order to improve the eccentric noncircular gear design flexibility to meet the requirements of more transmission characteristics, the generalized eccentric noncircular gear pitch curves were constructed based on the derivation of the tangent polar coordinates of eccentric curves. In order to facilitate the machining and design of this kind of noncircular gears, the convexity of the curves of the gears was deduced and the arc length formula was derived. This new generalized eccentric noncircular gear was used to drive the transverse seal mechanisms of horizontal pillow packing machines, which may meet the requirements better of horizontal sealing processes compared with conventional eccentric noncircular gears.
