作为优选的实施方式，输出轴50上设置有法兰盘51，法兰盘51上设置有第二通孔511，第二通孔511的数目为三个，第二传动轮40上还设置有三个第二传动轴42，第二传动轴42与第二通孔511相对应，第二传动轴42安装于第二通孔511。As a preferred embodiment, the
旋转架70上还设置有第三传动轴73，第三传动轴73与凸台72连接，第三传动轴73与凸台72的轴心不在同一轴线上，第三传动轴73以输入轴10为圆心做圆形轨迹的运动。A
输出轴50的底端上还设置有插槽，第三传动轴73插置于插槽，第三传动轴73可以在插槽内旋转，插槽的主要作用是为了使第三传动轴73更稳定，同时在旋转架70的底部设置的环形凸起75，底座61上设置与环形凸起75相适配的环形凹槽612，这些结构设置使得整个减速器旋转时更加稳固。The bottom end of the
如图7-10所示，为减速器的多个实施例简图，第二传动轮40与外壳60的轨道之间的啮合是摆线针齿轮组传动，当行星传动轮30数目为一个时，第三传动轴73以输入轴10为圆心做圆形轨迹的运动，第一传动轴71设置在旋转架70上，行星传动轮30与第二传动轮40的内齿啮合运动。As shown in Figures 7-10, which are schematic diagrams of various embodiments of the reducer, the engagement between the
当行星传动轮30数目为两个，与行星传动轮30相对应的第一传动轴71数目为两个，第三传动轴73以输入轴10为圆心做圆形轨迹的运动，两个行星传动轮是对称设置，两个第一传动轴71设置在上述圆形轨迹的两个动点上， 且两个第一传动轴71设置在旋转架70上，两个第一传动轴71与圆形轨迹的直径之间所形成的夹角相等，两个行星传动轮30在本实施例中可以增加第二传动轮40的均衡性，防止第二传动轮40在高速运动时出现抖动现象。When the number of the
当外部采用OTR活齿传动系时，由于第二传动轮40得到有效运行限位，故该减速器内部的旋转架70可以省略，此时第二传动轮40与外壳60的轨道之间的啮合是活齿传动，行星传动轮30没有传动轴连接，当行星传动轮30数目为一个时，行星传动轮30与第一传动轮20外啮合，同时行星传动轮30与第二传动轮40内啮合，这样整个减速器的成本就会降低。When the OTR movable gear train is externally used, since the
当行星传动轮30数目为两个，两个行星传动轮30分别设置于第一传动轮20两侧，行星传动轮30与第一传动轮20外啮合，行星传动轮30与第二传动轮40内啮合，这也是一个实施方式，此外，行星传动轮30的数目并不只两个，还可以为三个或四个，还包括别的实施例，这里不再列举。When the number of the
本申请以行星传动轮30与第一传动轮20的啮合所在的第一平面与第二传动轮40上的内外两面的啮合所在的第二平面都在同一平面上作为优先考虑的技术方案，但若第一平面与第二平面不在同一平面，在轴向上设置也可行，也在本申请保护范围内。In the present application, the second plane in which the first plane where the
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。The above embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention belong to the present invention.
