Zusammenfassung:A support rail for a swing gear includes a first flange having a first surface configured to engage a substantially horizontal top face of the swing gear, a second flange positioned opposite the first flange, and a column portion intersecting the first flange and the second flange such that the column portion is approximately perpendicular to the first and second flanges. The column portion includes a second surface configured to engage a substantially vertical inner surface of the swing gear. The first surface and the second surface are configured to substantially inhibit a rotation of the support rail relative to the swing gear by engaging the top face and the inner surface simultaneously. 种用于摆动齿轮的支承轨道包括第凸缘、第二凸缘以及柱部分,所述第凸缘具有配置成接合摆动齿轮的基本上水平的顶面的第表面,所述第二凸缘定位成与第凸缘相对,且所述柱部分与第凸缘和第二凸缘相交,以使得所述柱部分大致垂直于第凸缘和第二凸缘。所述柱部分包括第二表面,该第二表面配置成接合摆动齿轮的基本上竖直的内表面。第表面和第二表面配置成通过同时接合顶面和内表面来基本上抑制支承轨道相对于摆动齿轮的转动。
