行星机构及行星减速器
摘要：
本发明实施例提出一种行星机构，包括：第一输入轴；第二输入轴，与所述第一输入轴同轴设置，并可转动地连接于所述第一输入轴；第一中心轮，固定在所述第一输入轴上；第二中心轮，固定在所述第二输入轴上；行星架，能够绕所述第一输入轴和所述第二输入轴转动；第二行星轮，与所述第二中心轮相互啮合；第一行星轮，与所述第一中心轮相互啮合；第一行星轮与第二行星轮啮合；以及输出齿轮，与所述行星架同轴固定。本申请实施例提出的同轴式行星机构不仅能够达到现有NGW型行星减速器的效果，同时在设计时还无需要考虑诸多限制条件。
摘要（英）：

The embodiment of the invention provides a planetary mechanism. The planetary mechanism comprises a first input shaft, a second input shaft which is coaxial with the first input shaft and connected to the first input shaft in a rotary mode, a first center wheel fixed to the first input shaft, a second center wheel fixed to the second input shaft, a planet carrier capable of rotating around the first input shaft and the second input shaft, a second planet wheel engaging with the second center wheel, a first planet wheel engaging with the first center wheel and the second planet wheel, and an output gear fixed to the planet carrier coaxially. According to the coaxial type planetary mechanism, the effect of an existing NGW type planetary reducer can be realized, and limiting conditions do not need to be considered during designing.
