The invention relates to a two-stage planetary reducing mechanism which comprises a center transmission assembly and a two-stage planetary transmission assembly. The center transmission assembly comprises a main shaft, a first-stage sun gear and a second-stage sun gear, the first-stage planetary transmission assembly comprises a planet carrier connected to the main shaft in a sleeving mode, a planet shaft arranged on the planet carrier in a penetrating mode and parallel to the main shaft, a first-stage planet wheel located at one end of the planet shaft and meshed with the first-stage sun wheel, a first-stage gear ring meshed with the first-stage planet wheel, and a second-stage planet wheel located at the other end of the planet shaft and meshed with the second-stage sun wheel. And the second-stage gear ring is meshed with the second-stage planet wheel. The first-stage gear ring and the second-stage gear ring are arranged in a surrounding mode with the main shaft as the center. The invention further provides a wheel comprising the two-stage planetary reducing mechanism. The two-stage planetary reducer has the beneficial effects that the coaxial and different-speed two-stage planetary structure design is adopted, and the purposes of prolonging the service life, reducing the equipment cost and the like are achieved.

    本发明涉及一种两级行星减速机构,包括:中心传动组件和两级行星传动组件。中心传动组件包括:主轴,以及分别位于主轴上的一级太阳轮和二级太阳轮。一级行星传动组件包括:套接在主轴上的行星架、穿设在行星架上且平行于主轴设置的行星轴、位于行星轴的一端且啮合一级太阳轮的一级行星轮、啮合一级行星轮的一级齿环、位于行星轴的另一端且啮合二级太阳轮的二级行星轮、以及啮合二级行星轮的二级齿环。一级齿环和二级齿环均以主轴为中心环绕设置。本发明还提供一种包含该两级行星减速机构的轮子。本发明的有益效果为:采用同轴不同速的两级行星结构设计,达到延长使用寿命短和降低设备成本等目的。
